DALL·E Flow is an interactive workflow for generating high-definition images from a text prompt. It leverages DALL·E-Mega, GLID-3 XL, and Stable Diffusion to generate image candidates, and then calls CLIP-as-service to rank the candidates w.r.t. the prompt.
DALL·E Flow is an interactive workflow for generating high-definition images from a text prompt. Itt leverages DALL·E-Mega, GLID-3 XL, and Stable Diffusion to generate image candidates, and then calls CLIP-as-service to rank the candidates w.r.t. the prompt.
The preferred candidate is fed to GLID-3 XL for diffusion, which often enriches the texture and background. Finally, the candidate is upscaled to 1024x1024 via SwinIR.

# Documenting a model
# Utilizing the @auto_docstring Decorator
The `@auto_docstring` decorator in Transformers generates consistent docstrings for model classes and their methods. It reduces boilerplate by automatically including standard argument descriptions while also allowing overrides to add new or custom arguments. [Contributing a new model](./modular_transformers) is easier because you don't need to manually add the standard docstrings, and only focus on documenting new arguments.
The `@auto_docstring` decorator in the Hugging Face Transformers library helps generate docstrings for model classes and their methods, which will be used to build the documentation for the library. It aims to improve consistency and reduce boilerplate by automatically including standard argument descriptions and allowing for targeted overrides and additions.
This guide describes how to use the `@auto_docstring` decorator and how it works.
---
## @auto_docstring
## 📜 How it Works
Start by importing the decorator in the modeling file (`modular_model.py` or `modeling_model.py`).
The `@auto_docstring` decorator constructs docstrings by:
1. **Signature Inspection:** It inspects the signature (arguments, types, defaults) of the decorated class's `__init__` method or the decorated function.
2. **Centralized Docstring Fetching:** It retrieves predefined docstrings for common arguments (e.g., `input_ids`, `attention_mask`) from internal library sources (like `ModelArgs` or `ImageProcessorArgs` in `utils/args_doc.py`).
3. **Overriding or Adding Arguments Descriptions:**
* **Direct Docstring Block:** It incorporates custom docstring content from an `r""" """` (or `""" """`) block below the method signature or within the `__init__` docstring. This is for documenting new arguments or overriding standard descriptions.
* **Decorator Arguments (`custom_args`):** A `custom_args` docstring block can be passed to the decorator to provide docstrings for specific arguments directly in the decorator call. This can be used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file.
4. **Adding Classes and Functions Introduction:**
* **`custom_intro` argument:** Allows prepending a custom introductory paragraph to a class or function docstring.
* **Automatic Introduction Generation:** For model classes with standard naming patterns (like `ModelForCausalLM`) or belonging to a pipeline, the decorator automatically generates an appropriate introductory paragraph using `ClassDocstring` in `utils/args_doc.py` as the source.
5. **Templating:** The decorator uses a templating system, allowing predefined docstrings to include dynamic information deduced from the `auto_modules` of the library, such as `{{processor_class}}` or `{{config_class}}`.
6. **Deducing Relevant Examples:** The decorator attempts to find appropriate usage examples based on the model's task or pipeline compatibility. It extracts checkpoint information from the model's configuration class to provide concrete examples with real model identifiers.
7. **Adding Return Value Documentation:** For methods like `forward`, the decorator can automatically generate the "Returns" section based on the method's return type annotation. For example, for a method returning a `ModelOutput` subclass, it will extracts field descriptions from that class's docstring to create a comprehensive return value description. A custom `Returns` section can also be manually specified in the function docstring block.
8. **Unrolling Kwargs Typed With Unpack Operator:** For specific methods (defined in `UNROLL_KWARGS_METHODS`) or classes (defined in `UNROLL_KWARGS_CLASSES`), the decorator processes `**kwargs` parameters that are typed with `Unpack[KwargsTypedDict]`. It extracts the documentation from the TypedDict and adds each parameter to the function's docstring. Currently, this functionality is only supported for `FastImageProcessorKwargs`.

## Documenting arguments
### ✍️ Documenting Arguments: Approach & Priority
There are some rules for documenting different types of arguments and they're listed below.
- Standard arguments (`input_ids`, `attention_mask`, `pixel_values`, etc.) are defined and retrieved from `args_doc.py`. It is the single source of truth for standard arguments and should not be redefined locally if an argument's description and shape is the same as an argument in `args_doc.py`.
If a standard argument behaves differently in your model, then you can override it locally in a `r""" """` block. This local definition has a higher priority. For example, the `labels` argument is often customized per model and typically requires overriding.
- New or custom arguments should be documented within an `r""" """` block after the signature if it is a function or in the `__init__` method's docstring if it is a class.
```py
argument_name (`type`, *optional*, defaults to `X`):
Description of the argument.
Explain its purpose, expected shape/type if complex, and default behavior.
This can span multiple lines.
```
1. **Standard Arguments (e.g., `input_ids`, `attention_mask`, `pixel_values`, `encoder_hidden_states` etc.):**
* `@auto_docstring` retrieves descriptions from a central source. Do not redefine these locally if their description and shape are the same as in `args_doc.py`.
2. **New or Custom Arguments:**
* **Primary Method:** Document these within an `r""" """` docstring block following the signature (for functions) or in the `__init__` method's docstring (for class parameters).
* **Format:**
```
argument_name (`type`, *optional*, defaults to `X`):
Description of the argument.
Explain its purpose, expected shape/type if complex, and default behavior.
This can span multiple lines.
```
* Include `type` in backticks.
* Add *optional* if the argument is not required or has a default value.
* Add "defaults to X" if it has a default value. You don't need to add "defaults to `None`" if the default value is `None`.
* Add "*optional*" if the argument is not required (has a default value).
* Add "defaults to `X`" if it has a default value (no need to specify "defaults to `None`" if the default value is `None`).
These arguments can also be passed to `@auto_docstring` as a `custom_args` argument. It is used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file.
3. **Overriding Standard Arguments:**
* If a standard argument behaves differently (e.g., different expected shape, model-specific behavior), provide its complete description in the local `r""" """` docstring. This local definition takes precedence.
* The `labels` argument is often customized per model and typically requires a specific docstring.
```py
class MyModel(PreTrainedModel):
# ...
@auto_docstring(
custom_intro="""
This is a custom introduction for the function.
"""
custom_args=r"""
common_arg_1 (`torch.Tensor`, *optional*, defaults to `default_value`):
Description of common_arg_1
"""
)
```
4. **Using Decorator Arguments for Overrides or New Arguments (`custom_args`):**
* New or custom arguments docstrings can also be passed to `@auto_docstring` as a `custom_args` argument. This can be used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file.
## Checking the docstrings
---
Transformers includes a utility script to validate the docstrings when you open a Pull Request which triggers CI (continuous integration) checks. The script checks for the following criteria.
### Usage with [modular files](./modular_transformers)
* Ensures `@auto_docstring` is applied to relevant mode classes and public methods.
* Ensures arguments are complete and consistent. It checks that documented arguments exist in the signature and verifies whether the types and default values in the docstring match the signature. Arguments that aren't known standard arguments or if they lack a local description are flagged.
* Reminds you to complete placeholders like `<fill_type>` and `<fill_docstring>`.
* Ensures docstrings are formatted according to the expected docstring style.
When working with modular files, follow these guidelines for applying the `@auto_docstring` decorator:
You can run this check locally - before committing - by running the following command.
- **For standalone models in modular files:**
Apply the `@auto_docstring` decorator just as you would in regular modeling files.
- **For models inheriting from other library models:**
- When inheriting from a parent model, decorators (including `@auto_docstring`) are automatically carried over to the generated modeling file without needing to add them in your modular file.
- If you need to modify the `@auto_docstring` behavior, apply the customized decorator in your modular file, making sure to *include all other decorators* that were present on the original function/class.
> **Warning**: When overriding any decorator in a modular file, you must include ALL decorators that were applied to that function/class in the parent model. If you only override some decorators, the others won't be included in the generated modeling file.
**Note**: The `check_auto_docstrings` tool doesn't check modular files directly, but it will check (and modify when using `--fix_and_overwrite`) the generated modeling files. If issues are found in the generated files, you'll need to update your modular files accordingly.
---
## ✅ Checking Your Docstrings with `check_auto_docstrings`
The library includes a utility script to validate docstrings. This check is typically run during Continuous Integration (CI).
#### What it Checks:
* **Decorator Presence:** Ensures `@auto_docstring` is applied to relevant model classes and public methods. (TODO)
* **Argument Completeness & Consistency:**
* Flags arguments in the signature that are not known standard arguments and lack a local description.
* Ensures documented arguments exist in the signature. (TODO)
* Verifies that types and default values in the docstring match the signature. (TODO)
* **Placeholder Detection:** Reminds you to complete placeholders like `<fill_type>` or `<fill_docstring>`.
* **Formatting:** Adherence to the expected docstring style.
#### Running the Check Locally:
Run this check locally before committing. The common command is:
```bash
make fix-copies
```
`make fix-copies` runs several other checks as well. If you don't need those checks, run the command below to only perform docstring and auto-docstring checks.
Alternatively, to only perform docstrings and auto-docstring checks, you can use:
```bash
python utils/check_docstrings.py # to only check files included in the diff without fixing them
# python utils/check_docstrings.py --fix_and_overwrite # to fix and overwrite the files in the diff
# python utils/check_docstrings.py --fix_and_overwrite --check_all # to fix and overwrite all files
# Or: python utils/check_docstrings.py --fix_and_overwrite # to fix and overwrite the files in the diff
# Or: python utils/check_docstrings.py --fix_and_overwrite --check_all # to fix and overwrite all files
```
## modular_model.py files
#### Workflow with the Checker:
When working with modular files (`modular_model.py`), follow the guidelines below for applying `@auto_docstring`.
1. Add `@auto_docstring(...)` to the class or method.
2. For new, custom, or overridden arguments, add descriptions in an `r""" """` block.
3. Run `make fix-copies` (or the `check_docstrings.py` utility).
* For unrecognized arguments lacking documentation, the utility will create placeholder entries.
4. Manually edit these placeholders with accurate types and descriptions.
5. Re-run the check to ensure all issues are resolved.
- For standalone models in modular files, apply `@auto_docstring` like you would in a `modeling_model.py` file.
- For models that inherit from other library models, `@auto_docstring` is automatically carried over to the generated modeling file. You don't need to add `@auto_docstring` in your modular file.
---
If you need to modify the `@auto_docstring` behavior, apply the customized decorator in your modular file. Make sure to **include all other decorators** that are present in the original function or class.
## 🔑 Key Takeaways & Best Practices
> [!WARNING]
> When overriding any decorator in a modular file, you must include **all** decorators that were applied to that function or class in the parent model. If you only override some decorators, the others won't be included in the generated modeling file.
## How it works
The `@auto_docstring` decorator automatically generates docstrings by:
1. Inspecting the signature (arguments, types, defaults) of the decorated class' `__init__` method or the decorated function.
2. Retrieving the predefined docstrings for common arguments (`input_ids`, `attention_mask`, etc.) from internal library sources like [`ModelArgs`], [`ImageProcessorArgs`], and the `args_doc.py` file.
3. Adding argument descriptions in one of two ways as shown below.
| method | description | usage |
|---|---|---|
| `r""" """` | add custom docstring content directly to a method signature or within the `__init__` docstring | document new arguments or override standard descriptions |
| `custom_args` | add custom docstrings for specific arguments directly in `@auto_docstring` | define docstring for new arguments once if they're repeated in multiple places in the modeling file |
4. Adding class and function descriptions. For model classes with standard naming patterns, like `ModelForCausalLM`, or if it belongs to a pipeline, `@auto_docstring` automatically generates the appropriate descriptions with `ClassDocstring` from `args_doc.py`.
`@auto_docstring` also accepts the `custom_intro` argument to describe a class or function.
5. Using a templating system to allow predefined docstrings to include dynamic information from Transformers' [auto_modules](https://github.com/huggingface/transformers/tree/main/src/transformers/models/auto) such as `{{processor_class}}` and `{{config_class}}`.
6. Finding appropriate usage examples based on the model's task or pipeline compatibility. It extracts checkpoint information form the model's configuration class to provide concrete examples with real model identifiers.
7. Adding return values to the docstring. For methods like `forward`, the decorator automatically generates the `Returns` field in the docstring based on the method's return type annotation.
For example, if a method returns a [`~transformers.utils.ModelOutput`] subclass, `@auto_docstring` extracts the field descriptions from the class' docstring to create a comprehensive return value description. You can also manually specifiy a custom `Returns` field in a functions docstring.
8. Unrolling kwargs typed with the unpack operator. For specific methods (defined in `UNROLL_KWARGS_METHODS`) or classes (defined in `UNROLL_KWARGS_CLASSES`), the decorator processes `**kwargs` parameters that are typed with `Unpack[KwargsTypedDict]`. It extracts the documentations from the `TypedDict` and adds each parameter to the function's docstring.
Currently only supported for [`FastImageProcessorKwargs`].
## Best practices
Follow the best practices below to help maintain consistent and informative documentation for Transformers!
* Use `@auto_docstring` for new PyTorch model classes ([`PreTrainedModel`] subclasses) and their primary methods like `forward` or `get_text_features`.
* For classes, `@auto_docstring` retrieves parameter descriptions from the `__init__` method's docstring.
* Rely on standard docstrings and do not redefine common arguments unless their behavior is different in your model.
* Use `@auto_docstring` for new PyTorch model classes (`PreTrainedModel` subclasses) and their primary for methods (e.g., `forward`, `get_text_features` etc.).
* For classes, the `__init__` method's docstring is the main source for parameter descriptions when using `@auto_docstring` on the class.
* Rely on standard docstrings; do not redefine common arguments unless their behavior is different in your specific model.
* Document new or custom arguments clearly.
* Run `check_docstrings` locally and iteratively.
By following these guidelines, you help maintain consistent and informative documentation for the Hugging Face Transformers library 🤗.

2. The cache grows dynamically as more tokens are processed. The sequence length dimension (`seq_len`) increases with each new token.
3. The cache maintains a count of seen tokens through `self._seen_tokens`. This is updated when the first layer processes a new token.
The example below demonstrates how to create a generation loop with [`DynamicCache`]. As discussed, the attention mask is a concatenation of past and current token values and `1` is added to the cache position for the next token.

# AIMv2
## Overview
The AIMv2 model was proposed in [Multimodal Autoregressive Pre-training of Large Vision Encoders](https://arxiv.org/abs/2411.14402) by Enrico Fini, Mustafa Shukor, Xiujun Li, Philipp Dufter, Michal Klein, David Haldimann, Sai Aitharaju, Victor Guilherme Turrisi da Costa, Louis Béthune, Zhe Gan, Alexander T Toshev, Marcin Eichner, Moin Nabi, Yinfei Yang, Joshua M. Susskind, Alaaeldin El-Nouby.
The abstract from the paper is the following:
*We introduce a novel method for pre-training of large-scale vision encoders. Building on recent advancements in autoregressive pre-training of vision models, we extend this framework to a multimodal setting, i.e., images and text. In this paper, we present AIMV2, a family of generalist vision encoders characterized by a straightforward pre-training process, scalability, and remarkable performance across a range of downstream tasks. This is achieved by pairing the vision encoder with a multimodal decoder that autoregressively generates raw image patches and text tokens. Our encoders excel not only in multimodal evaluations but also in vision benchmarks such as localization, grounding, and classification. Notably, our AIMV2-3B encoder achieves 89.5% accuracy on ImageNet-1k with a frozen trunk. Furthermore, AIMV2 consistently outperforms state-of-the-art contrastive models (e.g., CLIP, SigLIP) in multimodal image understanding across diverse settings.*

## Usage Example
Here is an example of Image Feature Extraction using specific checkpoints on resized images and native resolution images:
```python
import requests
from PIL import Image
from transformers import AutoImageProcessor, AutoModel
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
processor = AutoImageProcessor.from_pretrained("apple/aimv2-large-patch14-native")
model = AutoModel.from_pretrained("apple/aimv2-large-patch14-native")
inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
```
Here is an example of a checkpoint performing zero-shot classification:
```python
import requests
from PIL import Image
from transformers import AutoProcessor, AutoModel
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
text = ["Picture of a dog.", "Picture of a cat.", "Picture of a horse."]
processor = AutoProcessor.from_pretrained("apple/aimv2-large-patch14-224-lit")
model = AutoModel.from_pretrained("apple/aimv2-large-patch14-224-lit")
inputs = processor(
images=image,
text=text,
add_special_tokens=True,
truncation=True,
padding=True,
return_tensors="pt",
)
outputs = model(**inputs)
probs = outputs.logits_per_image.softmax(dim=-1)

# BigBirdPegasus
[BigBirdPegasus](https://huggingface.co/papers/2007.14062) is an encoder-decoder (sequence-to-sequence) transformer model for long-input summarization. It extends the [BigBird](./big_bird) architecture with an additional pretraining objective borrowed from [Pegasus](./pegasus) called gap sequence generation (GSG). Whole sentences are masked and the model has to fill in the gaps in the document. BigBirdPegasus's ability to keep track of long contexts makes it effective at summarizing lengthy inputs, surpassing the performance of base Pegasus models.

The BigBird model was proposed in [Big Bird: Transformers for Longer Sequences](https://huggingface.co/papers/2007.14062) by
Zaheer, Manzil and Guruganesh, Guru and Dubey, Kumar Avinava and Ainslie, Joshua and Alberti, Chris and Ontanon,
Santiago and Pham, Philip and Ravula, Anirudh and Wang, Qifan and Yang, Li and others. BigBird, is a sparse-attention
based transformer which extends Transformer based models, such as BERT to much longer sequences. In addition to sparse
attention, BigBird also applies global attention as well as random attention to the input sequence. Theoretically, it
has been shown that applying sparse, global, and random attention approximates full attention, while being
computationally much more efficient for longer sequences. As a consequence of the capability to handle longer context,
BigBird has shown improved performance on various long document NLP tasks, such as question answering and
summarization, compared to BERT or RoBERTa.
The example below demonstrates how to summarize text with [`Pipeline`], [`AutoModel`], and from the command line.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*Transformers-based models, such as BERT, have been one of the most successful deep learning models for NLP.
Unfortunately, one of their core limitations is the quadratic dependency (mainly in terms of memory) on the sequence
length due to their full attention mechanism. To remedy this, we propose, BigBird, a sparse attention mechanism that
reduces this quadratic dependency to linear. We show that BigBird is a universal approximator of sequence functions and
is Turing complete, thereby preserving these properties of the quadratic, full attention model. Along the way, our
theoretical analysis reveals some of the benefits of having O(1) global tokens (such as CLS), that attend to the entire
sequence as part of the sparse attention mechanism. The proposed sparse attention can handle sequences of length up to
8x of what was previously possible using similar hardware. As a consequence of the capability to handle longer context,
BigBird drastically improves performance on various NLP tasks such as question answering and summarization. We also
propose novel applications to genomics data.*

## Notes
- BigBirdPegasus also uses the [`PegasusTokenizer`].
- Inputs should be padded on the right because BigBird uses absolute position embeddings.
- BigBirdPegasus supports `original_full` and `block_sparse` attention. If the input sequence length is less than 1024, it is recommended to use `original_full` since sparse patterns don't offer much benefit for smaller inputs.
- The current implementation uses window size of 3 blocks and 2 global blocks, only supports the ITC-implementation, and doesn't support `num_random_blocks=0`.
- The sequence length must be divisible by the block size.
- For an in-detail explanation on how BigBird's attention works, see [this blog post](https://huggingface.co/blog/big-bird).
- BigBird comes with 2 implementations: **original_full** & **block_sparse**. For the sequence length < 1024, using
**original_full** is advised as there is no benefit in using **block_sparse** attention.
- The code currently uses window size of 3 blocks and 2 global blocks.
- Sequence length must be divisible by block size.
- Current implementation supports only **ITC**.
- Current implementation doesn't support **num_random_blocks = 0**.
- BigBirdPegasus uses the [PegasusTokenizer](https://github.com/huggingface/transformers/blob/main/src/transformers/models/pegasus/tokenization_pegasus.py).
- BigBird is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.

# DeBERTa-v2
[DeBERTa-v2](https://huggingface.co/papers/2006.03654) improves on the original [DeBERTa](./deberta) architecture by using a SentencePiece-based tokenizer and a new vocabulary size of 128K. It also adds an additional convolutional layer within the first transformer layer to better learn local dependencies of input tokens. Finally, the position projection and content projection matrices are shared in the attention layer to reduce the number of parameters.

## Overview
The DeBERTa model was proposed in [DeBERTa: Decoding-enhanced BERT with Disentangled Attention](https://huggingface.co/papers/2006.03654) by Pengcheng He, Xiaodong Liu, Jianfeng Gao, Weizhu Chen It is based on Google's
BERT model released in 2018 and Facebook's RoBERTa model released in 2019.
It builds on RoBERTa with disentangled attention and enhanced mask decoder training with half of the data used in
RoBERTa.
The abstract from the paper is the following:
*Recent progress in pre-trained neural language models has significantly improved the performance of many natural
language processing (NLP) tasks. In this paper we propose a new model architecture DeBERTa (Decoding-enhanced BERT with
disentangled attention) that improves the BERT and RoBERTa models using two novel techniques. The first is the
disentangled attention mechanism, where each word is represented using two vectors that encode its content and
position, respectively, and the attention weights among words are computed using disentangled matrices on their
contents and relative positions. Second, an enhanced mask decoder is used to replace the output softmax layer to
predict the masked tokens for model pretraining. We show that these two techniques significantly improve the efficiency
of model pretraining and performance of downstream tasks. Compared to RoBERTa-Large, a DeBERTa model trained on half of
the training data performs consistently better on a wide range of NLP tasks, achieving improvements on MNLI by +0.9%
(90.2% vs. 91.1%), on SQuAD v2.0 by +2.3% (88.4% vs. 90.7%) and RACE by +3.6% (83.2% vs. 86.8%). The DeBERTa code and
pre-trained models will be made publicly available at https://github.com/microsoft/DeBERTa.*

The following information is visible directly on the [original implementation
repository](https://github.com/microsoft/DeBERTa). DeBERTa v2 is the second version of the DeBERTa model. It includes
the 1.5B model used for the SuperGLUE single-model submission and achieving 89.9, versus human baseline 89.8. You can
find more details about this submission in the authors'
[blog](https://www.microsoft.com/en-us/research/blog/microsoft-deberta-surpasses-human-performance-on-the-superglue-benchmark/)
The example below demonstrates how to classify text with [`Pipeline`] or the [`AutoModel`] class.
New in v2:
<hfoptions id="usage">
<hfoption id="Pipeline">
- **Vocabulary** In v2 the tokenizer is changed to use a new vocabulary of size 128K built from the training data.
Instead of a GPT2-based tokenizer, the tokenizer is now
[sentencepiece-based](https://github.com/google/sentencepiece) tokenizer.
- **nGiE(nGram Induced Input Encoding)** The DeBERTa-v2 model uses an additional convolution layer aside with the first
transformer layer to better learn the local dependency of input tokens.
- **Sharing position projection matrix with content projection matrix in attention layer** Based on previous
experiments, this can save parameters without affecting the performance.
- **Apply bucket to encode relative positions** The DeBERTa-v2 model uses log bucket to encode relative positions
similar to T5.
- **900M model & 1.5B model** Two additional model sizes are available: 900M and 1.5B, which significantly improves the
performance of downstream tasks.

# DeepSeek-V2
## Overview
The DeepSeek-V2 model was proposed in [DeepSeek-V2: A Strong, Economical, and Efficient Mixture-of-Experts Language Model](https://arxiv.org/abs/2405.04434) by DeepSeek-AI Team.
The abstract from the paper is the following:
We present DeepSeek-V2, a strong Mixture-of-Experts (MoE) language model characterized by economical training and efficient inference. It comprises 236B total parameters, of which 21B are activated for each token, and supports a context length of 128K tokens. DeepSeek-V2 adopts innovative architectures including Multi-head Latent Attention (MLA) and DeepSeekMoE. MLA guarantees efficient inference through significantly compressing the Key-Value (KV) cache into a latent vector, while DeepSeekMoE enables training strong models at an economical cost through sparse computation. Compared with DeepSeek 67B, DeepSeek-V2 achieves significantly stronger performance, and meanwhile saves 42.5% of training costs, reduces the KV cache by 93.3%, and boosts the maximum generation throughput to 5.76 times. We pretrain DeepSeek-V2 on a high-quality and multi-source corpus consisting of 8.1T tokens, and further perform Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL) to fully unlock its potential. Evaluation results show that, even with only 21B activated parameters, DeepSeek-V2 and its chat versions still achieve top-tier performance among open-source models.
This model was contributed by [VladOS95-cyber](https://github.com/VladOS95-cyber).
The original code can be found [here](https://huggingface.co/deepseek-ai/DeepSeek-V2).
### Usage tips
The model uses Multi-head Latent Attention (MLA) and DeepSeekMoE architectures for efficient inference and cost-effective training. It employs an auxiliary-loss-free strategy for load balancing and multi-token prediction training objective. The model can be used for various language tasks after being pre-trained on 14.8 trillion tokens and going through Supervised Fine-Tuning and Reinforcement Learning stages.

## Overview
Dia is an opensource text-to-speech (TTS) model (1.6B parameters) developed by [Nari Labs](https://huggingface.co/nari-labs).
It can generate highly realistic dialogue from transcript including nonverbal communications such as laughter and coughing.
Furthermore, emotion and tone control is also possible via audio conditioning (voice cloning).
**Model Architecture:**
Dia is an encoder-decoder transformer based on the original transformer architecture. However, some more modern features such as
rotational positional embeddings (RoPE) are also included. For its text portion (encoder), a byte tokenizer is utilized while
for the audio portion (decoder), a pretrained codec model [DAC](./dac.md) is used - DAC encodes speech into discrete codebook

# Doge
## Overview
Doge is a series of small language models based on the [Doge](https://github.com/SmallDoges/small-doge) architecture, aiming to combine the advantages of state-space and self-attention algorithms, calculate dynamic masks from cached value states using the zero-order hold method, and solve the problem of existing mainstream language models getting lost in context. It uses the `wsd_scheduler` scheduler to pre-train on the `smollm-corpus`, and can continue training on new datasets or add sparse activation feedforward networks from stable stage checkpoints.
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/refs%2Fpr%2F426/transformers/model_doc/doge_architecture.png" alt="drawing" width="600"/>
As shown in the figure below, the sequence transformation part of the Doge architecture uses `Dynamic Mask Attention`, which can be understood as using self-attention related to value states during training, and using state-space without past state decay during inference, to solve the problem of existing Transformers or SSMs getting lost in long text. The state transformation part of Doge uses `Cross Domain Mixture of Experts`, which consists of dense linear layers and sparse embedding layers, and can additionally increase sparse parameters to continue training from dense weight checkpoints without retraining the entire model, thereby reducing the cost of continuous iteration of the model. In addition, Doge also uses `RMSNorm` and `Residual` with learnable parameters to adapt the gradient range of deep models.

# dots.llm1
## Overview
The `dots.llm1` model was proposed in [dots.llm1 technical report](https://www.arxiv.org/pdf/2506.05767) by rednote-hilab team.
The abstract from the report is the following:
*Mixture of Experts (MoE) models have emerged as a promising paradigm for scaling language models efficiently by activating only a subset of parameters for each input token. In this report, we present dots.llm1, a large-scale MoE model that activates 14B parameters out of a total of 142B parameters, delivering performance on par with state-of-the-art models while reducing training and inference costs. Leveraging our meticulously crafted and efficient data processing pipeline, dots.llm1 achieves performance comparable to Qwen2.5-72B after pretraining on high-quality corpus and post-training to fully unlock its capabilities. Notably, no synthetic data is used during pretraining. To foster further research, we open-source intermediate training checkpoints spanning the entire training process, providing valuable insights into the learning dynamics of large language models.*

# EoMT

</div>
## Overview
The Encoder-only Mask Transformer (EoMT) model was introduced in the CVPR 2025 Highlight Paper [Your ViT is Secretly an Image Segmentation Model](https://www.tue-mps.org/eomt) by Tommie Kerssies, Niccolò Cavagnero, Alexander Hermans, Narges Norouzi, Giuseppe Averta, Bastian Leibe, Gijs Dubbelman, and Daan de Geus.
EoMT reveals Vision Transformers can perform image segmentation efficiently without task-specific components.
The abstract from the paper is the following:
*Vision Transformers (ViTs) have shown remarkable performance and scalability across various computer vision tasks. To apply single-scale ViTs to image segmentation, existing methods adopt a convolutional adapter to generate multi-scale features, a pixel decoder to fuse these features, and a Transformer decoder that uses the fused features to make predictions. In this paper, we show that the inductive biases introduced by these task-specific components can instead be learned by the ViT itself, given sufficiently large models and extensive pre-training. Based on these findings, we introduce the Encoder-only Mask Transformer (EoMT), which repurposes the plain ViT architecture to conduct image segmentation. With large-scale models and pre-training, EoMT obtains a segmentation accuracy similar to state-of-the-art models that use task-specific components. At the same time, EoMT is significantly faster than these methods due to its architectural simplicity, e.g., up to 4x faster with ViT-L. Across a range of model sizes, EoMT demonstrates an optimal balance between segmentation accuracy and prediction speed, suggesting that compute resources are better spent on scaling the ViT itself rather than adding architectural complexity.*
This model was contributed by [Yaswanth Gali](https://huggingface.co/yaswanthgali).
The original code can be found [here](https://github.com/tue-mps/eomt).
## Architecture Info
The `EoMT` model uses a DINOv2-pretrained Vision Transformer with **register tokens** as its backbone. EoMT simplifies the segmentation pipeline by relying solely on the encoder, eliminating the need for task-specific decoders commonly used in prior approaches.
Architecturally, EoMT introduces a small set of **learned queries** and a lightweight **mask prediction module**. These queries are injected into the final encoder blocks, enabling **joint attention** between image patches and object queries. During training, **masked attention** is applied to constrain each query to focus on its corresponding region—effectively mimicking cross-attention. This constraint is gradually phased out via a **mask annealing strategy**, allowing for **efficient, decoder-free inference** without compromising segmentation performance.
<div style="text-align: center;">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/eomt_architecture.png"
alt="drawing" width="500"/>
</div>
The model supports semantic, instance, and panoptic segmentation using a unified architecture and task-specific post-processing.
## Usage Examples
Use the Hugging Face implementation of EoMT for inference with pre-trained models.
### Semantic Segmentation
The EoMT model performs semantic segmentation using sliding-window inference. The input image is resized such that the shorter side matches the target input size, then it is split into overlapping crops. Each crop is then passed through the model. After inference, the predicted logits from each crop are stitched back together and rescaled to the original image size to get the final segmentation mask.
> **Note:**
> If you want to use a custom target size for **semantic segmentation**, specify it in the following format:
> `{"shortest_edge": 512}`
> Notice that `longest_edge` is not provided here — this is intentional. For semantic segmentation, images are typically **scaled so that the shortest edge is greater than or equal to the target size** hence longest_edge is not necessary.
```python
import matplotlib.pyplot as plt
import requests
import torch
from PIL import Image
from transformers import EomtForUniversalSegmentation, AutoImageProcessor
model_id = "tue-mps/ade20k_semantic_eomt_large_512"
processor = AutoImageProcessor.from_pretrained(model_id)
model = EomtForUniversalSegmentation.from_pretrained(model_id)
image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw)
inputs = processor(
images=image,
return_tensors="pt",
)
with torch.inference_mode():
outputs = model(**inputs)
# Prepare the original image size in the format (height, width)
target_sizes = [(image.height, image.width)]
# Post-process the model outputs to get final segmentation prediction
preds = processor.post_process_semantic_segmentation(
outputs,
target_sizes=target_sizes,
)
# Visualize the segmentation mask
plt.imshow(preds[0])
plt.axis("off")
plt.title("Semantic Segmentation")
plt.show()
```
### Instance Segmentation
The EoMT model performs instance segmentation using padded inference. The input image is resized so that the longer side matches the target input size, and the shorter side is zero-padded to form a square. The resulting mask and class logits are combined through post-processing (adapted from Mask2Former) to produce a unified instance segmentation map, along with segment metadata like segment id, class labels and confidence scores.
> **Note:**
> To use a custom target size, specify the size as a dictionary in the following format:
> `{"shortest_edge": 512, "longest_edge": 512}`
> For both instance and panoptic segmentation, input images will be **scaled and padded** to this target size.
```python
import matplotlib.pyplot as plt
import requests
import torch
from PIL import Image
from transformers import EomtForUniversalSegmentation, AutoImageProcessor
model_id = "tue-mps/coco_instance_eomt_large_640"
processor = AutoImageProcessor.from_pretrained(model_id)
model = EomtForUniversalSegmentation.from_pretrained(model_id)
image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw)
inputs = processor(
images=image,
return_tensors="pt",
)
with torch.inference_mode():
outputs = model(**inputs)
# Prepare the original image size in the format (height, width)
target_sizes = [(image.height, image.width)]
# Post-process the model outputs to get final segmentation prediction
preds = processor.post_process_instance_segmentation(
outputs,
target_sizes=target_sizes,
)
# Visualize the segmentation mask
plt.imshow(preds[0]["segmentation"])
plt.axis("off")
plt.title("Instance Segmentation")
plt.show()
```
### Panoptic Segmentation
The EoMT model performs panoptic segmentation using the same padded inference strategy as in instance segmentation. After padding and normalization, the model predicts both thing (instances) and stuff (amorphous regions) classes. The resulting mask and class logits are combined through post-processing (adapted from Mask2Former) to produce a unified panoptic segmentation map, along with segment metadata like segment id, class labels and confidence scores.
```python
import matplotlib.pyplot as plt
import requests
import torch
from PIL import Image
from transformers import EomtForUniversalSegmentation, AutoImageProcessor
model_id = "tue-mps/coco_panoptic_eomt_large_640"
processor = AutoImageProcessor.from_pretrained(model_id)
model = EomtForUniversalSegmentation.from_pretrained(model_id)
image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw)
inputs = processor(
images=image,
return_tensors="pt",
)
with torch.inference_mode():
outputs = model(**inputs)
# Prepare the original image size in the format (height, width)
target_sizes = [(image.height, image.width)]
# Post-process the model outputs to get final segmentation prediction
preds = processor.post_process_panoptic_segmentation(
outputs,
target_sizes=target_sizes,
)
# Visualize the panoptic segmentation mask
plt.imshow(preds[0]["segmentation"])
plt.axis("off")
plt.title("Panoptic Segmentation")
plt.show()
```

# Gemma3n
## Overview
Gemma3n is a multimodal model with pretrained and instruction-tuned variants, available in E4B and E2B sizes. While
large portions of the language model architecture are shared with prior Gemma releases, there are many new additions in
this model, including [Alternating Updates][altup] (AltUp), [Learned Augmented Residual Layer][laurel] (LAuReL),
[MatFormer][matformer], Per-Layer Embeddings (PLE), [Activation Sparsity with Statistical Top-k][spark-transformer], and KV cache sharing. The language model uses
a similar attention pattern to [Gemma 3](./gemma3.md) with alternating 4 local sliding window self-attention layers for
every global self-attention layer with a maximum context length of 32k tokens. Gemma 3n introduces
[MobileNet v5][mobilenetv5] as the vision encoder, using a default resolution of 768x768 pixels, and adds a newly
trained audio encoder based on the [Universal Speech Model][usm] (USM) architecture.
The instruction-tuned variant was post-trained with knowledge distillation and reinforcement learning.
You can find all the original Gemma 3n checkpoints under the [Gemma 3n][gemma3n-collection] release.
> [!TIP]

## Notes
- Use [`Gemma3nForConditionalGeneration`] for image-audio-and-text, image-and-text, image-and-audio, audio-and-text,
image-only and audio-only inputs.
- Gemma 3n supports multiple images per input, but make sure the images are correctly batched before passing them to
the processor. Each batch should be a list of one or more images.
```py
url_cow = "https://media.istockphoto.com/id/1192867753/photo/cow-in-berchida-beach-siniscola.jpg?s=612x612&w=0&k=20&c=v0hjjniwsMNfJSuKWZuIn8pssmD5h5bSN1peBd1CmH4="
url_cat = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
messages =[
{
"role": "system",
"content": [
{"type": "text", "text": "You are a helpful assistant."}
]
},
{
"role": "user",
"content": [
{"type": "image", "url": url_cow},
{"type": "image", "url": url_cat},
{"type": "text", "text": "Which image is cuter?"},
]
},
]
```
- Text passed to the processor should have a `<image_soft_token>` token wherever an image should be inserted.
- Gemma 3n accept at most one target audio clip per input, though multiple audio clips can be provided in few-shot
prompts, for example.
- Text passed to the processor should have a `<audio_soft_token>` token wherever an audio clip should be inserted.
- The processor has its own [`~ProcessorMixin.apply_chat_template`] method to convert chat messages to model inputs.

was pre-trained on 15T of high-quality data, including substantial reasoning-type synthetic data. This lays the
foundation for subsequent reinforcement learning extensions. In the post-training stage, we employed human preference
alignment for dialogue scenarios. Additionally, using techniques like rejection sampling and reinforcement learning, we
enhanced the models performance in instruction following, engineering code, and function calling, thus strengthening
the atomic capabilities required for agent tasks. GLM-4-32B-0414 achieves good results in engineering code, Artifact
generation, function calling, search-based Q&A, and report generation. In particular, on several benchmarks, such as
code generation or specific Q&A tasks, GLM-4-32B-Base-0414 achieves comparable performance with those larger models like
GPT-4o and DeepSeek-V3-0324 (671B).
**GLM-Z1-32B-0414** is a reasoning model with deep thinking capabilities. This was developed based on GLM-4-32B-0414
through cold start, extended reinforcement learning, and further training on tasks including mathematics, code, and
logic. Compared to the base model, GLM-Z1-32B-0414 significantly improves mathematical abilities and the capability to
solve complex tasks. During training, we also introduced general reinforcement learning based on pairwise ranking
feedback, which enhances the model's general capabilities.
**GLM-Z1-Rumination-32B-0414** is a deep reasoning model with rumination capabilities (against OpenAI's Deep Research).
Unlike typical deep thinking models, the rumination model is capable of deeper and longer thinking to solve more
open-ended and complex problems (e.g., writing a comparative analysis of AI development in two cities and their future
development plans). Z1-Rumination is trained through scaling end-to-end reinforcement learning with responses graded by
the ground truth answers or rubrics and can make use of search tools during its deep thinking process to handle complex
tasks. The model shows significant improvements in research-style writing and complex tasks.
Finally, **GLM-Z1-9B-0414** is a surprise. We employed all the aforementioned techniques to train a small model (9B).
GLM-Z1-9B-0414 exhibits excellent capabilities in mathematical reasoning and general tasks. Its overall performance is
top-ranked among all open-source models of the same size. Especially in resource-constrained scenarios, this model
achieves an excellent balance between efficiency and effectiveness, providing a powerful option for users seeking
lightweight deployment.
To be released with the official model launch.

# GLM-4.1V
## Overview
**GLM-4.1V-9B-Thinking** is a bilingual vision-language model optimized for reasoning, built on GLM-4-9B. It introduces
a "thinking paradigm" with reinforcement learning, achieving state-of-the-art results among 10B-class models and
rivaling 72B-scale models. It supports 64k context, 4K resolution, and arbitrary aspect ratios, with an open-source base
model for further research. You can check our paper [here](https://huggingface.co/papers/2507.01006). and below is a abstract.
*We present GLM-4.1V-Thinking, a vision-language model (VLM) designed to advance general-purpose multimodal understanding
and reasoning. In this report, we share our key findings in the development of the reasoning-centric training framework.
We first develop a capable vision foundation model with significant potential through large-scale pre-training, which
arguably sets the upper bound for the final performance. We then propose Reinforcement Learning with Curriculum
Sampling (RLCS) to unlock the full potential of the model, leading to comprehensive capability enhancement across a
diverse range of tasks, including STEM problem solving, video understanding, content recognition, coding, grounding,
GUI-based agents, and long document understanding. We open-source GLM-4.1V-9B-Thinking, which achieves state-of-the-art
performance among models of comparable size. In a comprehensive evaluation across 28 public benchmarks, our model
outperforms Qwen2.5-VL-7B on nearly all tasks and achieves comparable or even superior performance on 18 benchmarks
relative to the significantly larger Qwen2.5-VL-72B. Notably, GLM-4.1V-9B-Thinking also demonstrates competitive or
superior performance compared to closed-source models such as GPT-4o on challenging tasks including long document
understanding and STEM reasoning, further underscoring its strong capabilities. Code, models and more information
are released at https://github.com/THUDM/GLM-4.1V-Thinking.*

# LED
[Longformer-Encoder-Decoder (LED)](https://huggingface.co/papers/2004.05150) is an encoder-decoder transformer model for sequence-to-sequence tasks like summarization. It extends [Longformer](.longformer), an encoder-only model designed to handle long inputs, by adding a decoder layer. The decoder uses full self-attention on the encoded tokens and previously decoded locations. Because of Longformer's linear self-attention mechanism, LED is more efficient than standard encoder-decoder models when processing long sequences.

The LED model was proposed in [Longformer: The Long-Document Transformer](https://huggingface.co/papers/2004.05150) by Iz
Beltagy, Matthew E. Peters, Arman Cohan.
The example below demonstrates how to summarize text with [`Pipeline`], [`AutoModel`], and from the command line.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*Transformer-based models are unable to process long sequences due to their self-attention operation, which scales
quadratically with the sequence length. To address this limitation, we introduce the Longformer with an attention
mechanism that scales linearly with sequence length, making it easy to process documents of thousands of tokens or
longer. Longformer's attention mechanism is a drop-in replacement for the standard self-attention and combines a local
windowed attention with a task motivated global attention. Following prior work on long-sequence transformers, we
evaluate Longformer on character-level language modeling and achieve state-of-the-art results on text8 and enwik8. In
contrast to most prior work, we also pretrain Longformer and finetune it on a variety of downstream tasks. Our
pretrained Longformer consistently outperforms RoBERTa on long document tasks and sets new state-of-the-art results on
WikiHop and TriviaQA. We finally introduce the Longformer-Encoder-Decoder (LED), a Longformer variant for supporting
long document generative sequence-to-sequence tasks, and demonstrate its effectiveness on the arXiv summarization
dataset.*

pipeline("""Plants are among the most remarkable and essential life forms on Earth, possessing a unique ability to produce their own food through a process known as photosynthesis. This complex biochemical process is fundamental not only to plant life but to virtually all life on the planet.
Through photosynthesis, plants capture energy from sunlight using a green pigment called chlorophyll, which is located in specialized cell structures called chloroplasts. In the presence of light, plants absorb carbon dioxide from the atmosphere through small pores in their leaves called stomata, and take in water from the soil through their root systems.
These ingredients are then transformed into glucose, a type of sugar that serves as a source of chemical energy, and oxygen, which is released as a byproduct into the atmosphere. The glucose produced during photosynthesis is not just used immediately; plants also store it as starch or convert it into other organic compounds like cellulose, which is essential for building their cellular structure.
This energy reserve allows them to grow, develop leaves, produce flowers, bear fruit, and carry out various physiological processes throughout their lifecycle.""")

- [`LEDForConditionalGeneration`] is an extension of
[`BartForConditionalGeneration`] exchanging the traditional *self-attention* layer with
*Longformer*'s *chunked self-attention* layer. [`LEDTokenizer`] is an alias of
[`BartTokenizer`].
- LED works very well on long-range *sequence-to-sequence* tasks where the `input_ids` largely exceed a length of
1024 tokens.
- LED pads the `input_ids` to be a multiple of `config.attention_window` if required. Therefore a small speed-up is
gained, when [`LEDTokenizer`] is used with the `pad_to_multiple_of` argument.
- LED makes use of *global attention* by means of the `global_attention_mask` (see
[`LongformerModel`]). For summarization, it is advised to put *global attention* only on the first
`<s>` token. For question answering, it is advised to put *global attention* on all tokens of the question.
- To fine-tune LED on all 16384, *gradient checkpointing* can be enabled in case training leads to out-of-memory (OOM)
errors. This can be done by executing `model.gradient_checkpointing_enable()`.
Moreover, the `use_cache=False`
flag can be used to disable the caching mechanism to save memory.
- LED is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.

## Notes
- [`LEDForConditionalGeneration`] is an extension of [`BartForConditionalGeneration`] exchanging the traditional self-attention layer with Longformer's chunked self-attention layer. [`LEDTokenizer`] is an alias of [`BartTokenizer`].
- LED pads the `input_ids` to be a multiple of `config.attention_window` if required. A small speedup is gained when [`LEDTokenizer`] is used with the `pad_to_multiple_of` argument.
- LED works best on long-range sequence-to-sequence tasks where the `input_ids` are significantly longer than 1024 tokens.
- LED uses global attention by means of the `global_attention_mask` (see [`LongformerModel`]). For summarization, it is advised to put global attention only on the first `<s>` token. For question answering, it is advised to put global attention on all tokens of the question.
- To fine-tune LED on all 16384 parameters, gradient checkpointing can be enabled in case training leads to out-of-memory (OOM) errors. Enable gradient checkpointing by adding `model.gradient_checkpointing_enable()` and setting `use_cache=False` to disable the caching mechanism to save memory.
- Inputs should be padded on the right because LED uses absolute position embeddings.

# LFM2
## Overview
[LFM2](https://www.liquid.ai/blog/liquid-foundation-models-v2-our-second-series-of-generative-ai-models) represents a new generation of Liquid Foundation Models developed by [Liquid AI](https://liquid.ai/), specifically designed for edge AI and on-device deployment.
The models are available in three sizes (350M, 700M, and 1.2B parameters) and are engineered to run efficiently on CPU, GPU, and NPU hardware, making them particularly well-suited for applications requiring low latency, offline operation, and privacy.
## Architecture
The architecture consists of 16 blocks total: 10 double-gated short-range convolution blocks and 6 blocks of grouped query attention. This design stems from the concept of dynamical systems, where linear operations are modulated by input-dependent gates, allowing for "liquid" dynamics that can adapt in real-time. The short convolutions are particularly optimized for embedded SoC CPUs, making them ideal for devices that require fast, local inference without relying on cloud connectivity.
The key architectural innovation of LFM2 lies in its systematic approach to balancing quality, latency, and memory efficiency through our STAR neural architecture search engine. Using STAR, Liquid AI optimized the models for real-world performance on embedded hardware, measuring actual peak memory usage and inference speed on Qualcomm Snapdragon processors. This results in models that achieve 2x faster decode and prefill performance compared to similar-sized models, while maintaining superior benchmark performance across knowledge, mathematics, instruction following, and multilingual tasks.
## Example
The following example shows how to generate an answer using the `AutoModelForCausalLM` class.
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
# Load model and tokenizer
model_id = "LiquidAI/LFM2-1.2B"
model = AutoModelForCausalLM.from_pretrained(
model_id,
device_map="auto",
torch_dtype="bfloat16",
)
tokenizer = AutoTokenizer.from_pretrained(model_id)
# Generate answer
prompt = "What is C. elegans?"
input_ids = tokenizer.apply_chat_template(
[{"role": "user", "content": prompt}],
add_generation_prompt=True,
return_tensors="pt",
tokenize=True,
)
output = model.generate(
input_ids,
do_sample=True,
temperature=0.3,
min_p=0.15,
repetition_penalty=1.05,
max_new_tokens=512,
)
print(tokenizer.decode(output[0], skip_special_tokens=False))

# LLaVA-NeXT
[LLaVANeXT](https://llava-vl.github.io/blog/2024-05-10-llava-next-stronger-llms/) improves on [Llava](./llava) by increasing the input image resolution by 4x more pixels and supporting 3 aspect ratios (up to 672x672, 336x1344, 1344x336) to better grasp visual details. It is also trained on an improved visual instruction tuning dataset covering more scenarios and applications to improve OCR and common sense reasoning.

You can find all the original LLaVANeXT checkpoints under the [LLaVA-NeXT](https://huggingface.co/collections/llava-hf/llava-next-65f75c4afac77fd37dbbe6cf) collection.
## Overview
> [!TIP]
> This model was contributed by [nielsr](https://huggingface.co/nielsr).
>
> Click on the LLaVANeXT models in the right sidebar for more examples of how to apply Llava-NeXT to different multimodal tasks.
The LLaVA-NeXT model was proposed in [LLaVA-NeXT: Improved reasoning, OCR, and world knowledge](https://llava-vl.github.io/blog/2024-01-30-llava-next/) by Haotian Liu, Chunyuan Li, Yuheng Li, Bo Li, Yuanhan Zhang, Sheng Shen, Yong Jae Lee. LLaVa-NeXT (also called LLaVa-1.6) improves upon [LLaVa](llava) by increasing the input image resolution and training on an improved visual instruction tuning dataset to improve OCR and common sense reasoning.
The example below demonstrates how to generate text based on an image with [`Pipeline`] or the [`AutoModel`] class.
The introduction from the blog is the following:
<hfoptions id="usage">
*In October 2023, we released LLaVA-1.5 with a simple and efficient design along with great performance on a benchmark suite of 12 datasets. It has since served as the foundation of many comprehensive studies of data, model, and capabilities of large multimodal models (LMM), and has enabled various new applications.
<hfoption id="Pipeline">
Today, we are thrilled to present LLaVA-NeXT, with improved reasoning, OCR, and world knowledge. LLaVA-NeXT even exceeds Gemini Pro on several benchmarks.
Compared with LLaVA-1.5, LLaVA-NeXT has several improvements:
Increasing the input image resolution to 4x more pixels. This allows it to grasp more visual details. It supports three aspect ratios, up to 672x672, 336x1344, 1344x336 resolution.
Better visual reasoning and OCR capability with an improved visual instruction tuning data mixture.
Better visual conversation for more scenarios, covering different applications. Better world knowledge and logical reasoning.
Efficient deployment and inference with SGLang.
Along with performance improvements, LLaVA-NeXT maintains the minimalist design and data efficiency of LLaVA-1.5. It re-uses the pretrained connector of LLaVA-1.5, and still uses less than 1M visual instruction tuning samples. The largest 34B variant finishes training in ~1 day with 32 A100s.*

<small> LLaVa-NeXT incorporates a higher input resolution by encoding various patches of the input image. Taken from the <a href="https://huggingface.co/papers/2310.03744">original paper.</a> </small>
This model was contributed by [nielsr](https://huggingface.co/nielsr).
The original code can be found [here](https://github.com/haotian-liu/LLaVA/tree/main).
## Usage tips
- We advise users to use `padding_side="left"` when computing batched generation as it leads to more accurate results. Simply make sure to call `processor.tokenizer.padding_side = "left"` before generating.
<Tip warning={true}>
- Llava-Next uses different number of patches for images and thus has to pad the inputs inside modeling code, aside from the padding done when processing the inputs. The default setting is "left-padding" if model is in `eval()` mode, otherwise "right-padding".
</Tip>
> [!NOTE]
> LLaVA models after release v4.46 will raise warnings about adding `processor.patch_size = {{patch_size}}`, `processor.num_additional_image_tokens = {{num_additional_image_tokens}}` and processor.vision_feature_select_strategy = {{vision_feature_select_strategy}}`. It is strongly recommended to add the attributes to the processor if you own the model checkpoint, or open a PR if it is not owned by you.
Adding these attributes means that LLaVA will try to infer the number of image tokens required per image and expand the text with as many `<image>` placeholders as there will be tokens. Usually it is around 500 tokens per image, so make sure that the text is not truncated as otherwise there will be failure when merging the embeddings.
The attributes can be obtained from model config, as `model.config.vision_config.patch_size` or `model.config.vision_feature_select_strategy`. The `num_additional_image_tokens` should be `1` if the vision backbone adds a CLS token or `0` if nothing extra is added to the vision patches.
### Formatting Prompts with Chat Templates
Each **checkpoint** is trained with a specific prompt format, depending on the underlying large language model backbone. To ensure correct formatting, use the processors `apply_chat_template` method.
**Important:**
- You must construct a conversation history — passing a plain string won't work.
- Each message should be a dictionary with `"role"` and `"content"` keys.
- The `"content"` should be a list of dictionaries for different modalities like `"text"` and `"image"`.
Heres an example of how to structure your input. We will use [llava-v1.6-mistral-7b-hf](https://huggingface.co/llava-hf/llava-v1.6-mistral-7b-hf) and a conversation history of text and image.

text_prompt = processor.apply_chat_template(conversation, add_generation_prompt=True)
# Note that the template simply formats your prompt, you still have to tokenize it and obtain pixel values for your images
print(text_prompt)

```

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to int4.
```python
import torch
import requests
from PIL import Image
from transformers import AutoModelForImageTextToText, AutoProcessor, BitsAndBytesConfig
quant_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_compute_dtype=torch.float16,
bnb_4bit_quant_type="nf4"
)
processor = AutoProcessor.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf")
model = AutoModelForImageTextToText.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf", quantization_config=quant_config, device_map="auto")

]
prompt = processor.apply_chat_template(conversation, add_generation_prompt=True)
inputs = processor(image, prompt, return_tensors="pt").to("cuda")
with torch.inference_mode():
output = model.generate(**inputs, max_new_tokens=100)
print(processor.decode(output[0], skip_special_tokens=True))
[llava-v1.6-vicuna-7b-hf](https://huggingface.co/llava-hf/llava-v1.6-vicuna-7b-hf) and [llava-v1.6-vicuna-13b-hf](https://huggingface.co/llava-hf/llava-v1.6-vicuna-13b-hf) require the following format:
```bash
"A chat between a curious human and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the human's questions. USER: <image>\nWhat is shown in this image? ASSISTANT:"
```
## Notes
* Different checkpoints (Mistral, Vicuna, etc.) require a specific prompt format depending on the underlying LLM. Always use [`~ProcessorMixin.apply_chat_template`] to ensure correct formatting. Refer to the [Templates](../chat_templating) guide for more details.
* Set `padding_side="left"` during batched generation for more accurate results.

processor.tokenizer.padding_side = "left"
[llava-v1.6-34b-hf](https://huggingface.co/llava-hf/llava-v1.6-34b-hf) requires the following format:
```bash
"<|im_start|>system\nAnswer the questions.<|im_end|><|im_start|>user\n<image>\nWhat is shown in this image?<|im_end|><|im_start|>assistant\n"
```
* LLaVA-NeXT uses different numbers of patches for images and pads the inputs inside the modeling code except when padding is done during processing. The default setting is *left-padding* if the model is in `eval()` mode, otherwise it is *right-padding*.
[llama3-llava-next-8b-hf](https://huggingface.co/llava-hf/llava-next-8b-hf) requires the following format:
* LLaVA models after v4.46 raises warnings about adding `processor.patch_size = {{patch_size}}`, `processor.num_additional_image_tokens = {{num_additional_image_tokens}}`, and `processor.vision_feature_select_strategy = {{vision_feature_select_strategy}}`. It is strongly recommended to add these attributes to the processor if you own the model checkpoint or open a PR if it isn't.
```bash
"<|start_header_id|>system<|end_header_id|>\n\nYou are a helpful language and vision assistant. You are able to understand the visual content that the user provides, and assist the user with a variety of tasks using natural language.<|eot_id|><|start_header_id|><|start_header_id|>user<|end_header_id|>\n\n<image>\nWhat is shown in this image?<|eot_id|><|start_header_id|>assistant<|end_header_id|>\n\n"
```
Adding these attributes means LLaVA will try to infer the number of image tokens required per image and expand the text with the same number of `<image>` token placeholders. There are usually ~500 tokens per image, so make sure the text is not truncated because it will cause a failure when merging the embeddings. The attributes can be found in `model.config.vision_config.patch_size` or `model.config.vision_feature_select_strategy`.
[llava-next-72b-hf](https://huggingface.co/llava-hf/llava-next-72b-hf) and [llava-next-110b-hf](https://huggingface.co/llava-hf/llava-next-110b-hf) require the following format:
The `num_additional_image_tokens` should be `1` if the vision backbone adds a `CLS` token or `0` if nothing extra is added.
```bash
"<|im_start|>system\nYou are a helpful assistant.<|im_end|>\n<|im_start|>user\n<image>\nWhat is shown in this image?<|im_end|>\n<|im_start|>assistant\n"
```
* The example below demonstrates inference with multiple input images.
🚀 **Bonus:** If you're using `transformers>=4.49.0`, you can also get a vectorized output from `apply_chat_template`. See the **Usage Examples** below for more details on how to use it.
## Usage example
### Single image inference
Here's how to load the model and perform inference in half-precision (`torch.float16`):
```python
from transformers import LlavaNextProcessor, LlavaNextForConditionalGeneration
import torch
from PIL import Image
import requests, torch
import requests
processor = LlavaNextProcessor.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf")
model = LlavaNextForConditionalGeneration.from_pretrained(
"llava-hf/llava-v1.6-mistral-7b-hf", torch_dtype=torch.float16
).to("cuda")
# Load multiple images
url1 = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/llava_next_ocr.png"
url2 = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/llava_next_comparison.png"
model = LlavaNextForConditionalGeneration.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf", torch_dtype=torch.float16)
model.to("cuda:0")
image1 = Image.open(requests.get(url1, stream=True).raw)
image2 = Image.open(requests.get(url2, stream=True).raw)
# prepare image and text prompt, using the appropriate prompt template
url = "https://github.com/haotian-liu/LLaVA/blob/1a91fc274d7c35a9b50b3cb29c4247ae5837ce39/images/llava_v1_5_radar.jpg?raw=true"
image = Image.open(requests.get(url, stream=True).raw)
conversation = [
{"role": "user", "content": [{"type": "image"}, {"type": "image"}, {"type": "text", "text": "Compare these two images and describe the differences."}]}
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "What is shown in this image?"},
],
},
]
prompt = processor.apply_chat_template(conversation, add_generation_prompt=True)
inputs = processor([image1, image2], prompt, return_tensors="pt").to("cuda")
inputs = processor(image, prompt, return_tensors="pt").to("cuda:0")
# autoregressively complete prompt
output = model.generate(**inputs, max_new_tokens=100)
print(processor.decode(output[0], skip_special_tokens=True))
```
### Multi image inference
LLaVa-Next can perform inference with multiple images as input, where images either belong to the same prompt or different prompts (in batched inference). Here is how you can do it:
```python
import requests
from PIL import Image
import torch
from transformers import AutoProcessor, AutoModelForImageTextToText
# Load the model in half-precision
model = AutoModelForImageTextToText.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf", torch_dtype=torch.float16, device_map="auto")
processor = AutoProcessor.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf")
# Get three different images
url = "https://www.ilankelman.org/stopsigns/australia.jpg"
image_stop = Image.open(requests.get(url, stream=True).raw)
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image_cats = Image.open(requests.get(url, stream=True).raw)
url = "https://huggingface.co/microsoft/kosmos-2-patch14-224/resolve/main/snowman.jpg"
image_snowman = Image.open(requests.get(url, stream=True).raw)
# Prepare a batch of two prompts, where the first one is a multi-turn conversation and the second is not
conversation_1 = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "What is shown in this image?"},
],
},
{
"role": "assistant",
"content": [
{"type": "text", "text": "There is a red stop sign in the image."},
],
},
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "What about this image? How many cats do you see?"},
],
},
]
conversation_2 = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "What is shown in this image?"},
],
},
]
prompt_1 = processor.apply_chat_template(conversation_1, add_generation_prompt=True)
prompt_2 = processor.apply_chat_template(conversation_2, add_generation_prompt=True)
prompts = [prompt_1, prompt_2]
# We can simply feed images in the order they have to be used in the text prompt
# Each "<image>" token uses one image leaving the next for the subsequent "<image>" tokens
inputs = processor(images=[image_stop, image_cats, image_snowman], text=prompts, padding=True, return_tensors="pt").to(model.device)
# Generate
generate_ids = model.generate(**inputs, max_new_tokens=30)
processor.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)
```
## Model optimization
### Quantization using Bitsandbytes
The model can be loaded in 8 or 4 bits, greatly reducing the memory requirements while maintaining the performance of the original model. First make sure to install bitsandbytes, `pip install bitsandbytes`, and to have access to a GPU/accelerator that is supported by the library.
<Tip>
bitsandbytes is being refactored to support multiple backends beyond CUDA. Currently, ROCm (AMD GPU) and Intel CPU implementations are mature, with Intel XPU in progress and Apple Silicon support expected by Q4/Q1. For installation instructions and the latest backend updates, visit [this link](https://huggingface.co/docs/bitsandbytes/main/en/installation#multi-backend).
We value your feedback to help identify bugs before the full release! Check out [these docs](https://huggingface.co/docs/bitsandbytes/main/en/non_cuda_backends) for more details and feedback links.
</Tip>
Simply change the snippet above with:
```python
from transformers import AutoModelForImageTextToText, BitsAndBytesConfig
# specify how to quantize the model
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.float16,
)
model = AutoModelForImageTextToText.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf", quantization_config=quantization_config, device_map="auto")
```
### Use Flash-Attention 2 to further speed-up generation
First make sure to install flash-attn. Refer to the [original repository of Flash Attention](https://github.com/Dao-AILab/flash-attention) regarding that package installation. Simply change the snippet above with:
```python
from transformers import AutoModelForImageTextToText
model = AutoModelForImageTextToText.from_pretrained(
model_id,
torch_dtype=torch.float16,
use_flash_attention_2=True
).to(0)
```

# MarianMT
[MarianMT](https://huggingface.co/papers/1804.00344) is a machine translation model trained with the Marian framework which is written in pure C++. The framework includes its own custom auto-differentiation engine and efficient meta-algorithms to train encoder-decoder models like BART.
All MarianMT models are transformer encoder-decoders with 6 layers in each component, use static sinusoidal positional embeddings, don't have a layernorm embedding, and the model starts generating with the prefix `pad_token_id` instead of `<s/>`.
You can find all the original MarianMT checkpoints under the [Language Technology Research Group at the University of Helsinki](https://huggingface.co/Helsinki-NLP/models?search=opus-mt) organization.

## Notes
## Overview
- MarianMT models are ~298MB on disk and there are more than 1000 models. Check this [list](https://huggingface.co/Helsinki-NLP) for supported language pairs. The language codes may be inconsistent. Two digit codes can be found [here](https://developers.google.com/admin-sdk/directory/v1/languages) while three digit codes may require further searching.
- Models that require BPE preprocessing are not supported.
- All model names use the following format: `Helsinki-NLP/opus-mt-{src}-{tgt}`. Language codes formatted like `es_AR` usually refer to the `code_{region}`. For example, `es_AR` refers to Spanish from Argentina.
- If a model can output multiple languages, prepend the desired output language to `src_txt` as shown below. New multilingual models from the [Tatoeba-Challenge](https://github.com/Helsinki-NLP/Tatoeba-Challenge) require 3 character language codes.
A framework for translation models, using the same models as BART. Translations should be similar, but not identical to output in the test set linked to in each model card.
This model was contributed by [sshleifer](https://huggingface.co/sshleifer).
## Implementation Notes
- Each model is about 298 MB on disk, there are more than 1,000 models.
- The list of supported language pairs can be found [here](https://huggingface.co/Helsinki-NLP).
- Models were originally trained by [Jörg Tiedemann](https://researchportal.helsinki.fi/en/persons/j%C3%B6rg-tiedemann) using the [Marian](https://marian-nmt.github.io/) C++ library, which supports fast training and translation.
- All models are transformer encoder-decoders with 6 layers in each component. Each model's performance is documented
in a model card.
- The 80 opus models that require BPE preprocessing are not supported.
- The modeling code is the same as [`BartForConditionalGeneration`] with a few minor modifications:
- static (sinusoid) positional embeddings (`MarianConfig.static_position_embeddings=True`)
- no layernorm_embedding (`MarianConfig.normalize_embedding=False`)
- the model starts generating with `pad_token_id` (which has 0 as a token_embedding) as the prefix (Bart uses
`<s/>`),
- Code to bulk convert models can be found in `convert_marian_to_pytorch.py`.
## Naming
- All model names use the following format: `Helsinki-NLP/opus-mt-{src}-{tgt}`
- The language codes used to name models are inconsistent. Two digit codes can usually be found [here](https://developers.google.com/admin-sdk/directory/v1/languages), three digit codes require googling "language
code {code}".
- Codes formatted like `es_AR` are usually `code_{region}`. That one is Spanish from Argentina.
- The models were converted in two stages. The first 1000 models use ISO-639-2 codes to identify languages, the second
group use a combination of ISO-639-5 codes and ISO-639-2 codes.
## Examples
- Since Marian models are smaller than many other translation models available in the library, they can be useful for
fine-tuning experiments and integration tests.
- [Fine-tune on GPU](https://github.com/huggingface/transformers/blob/master/examples/legacy/seq2seq/train_distil_marian_enro.sh)
## Multilingual Models
- All model names use the following format: `Helsinki-NLP/opus-mt-{src}-{tgt}`:
- If a model can output multiple languages, and you should specify a language code by prepending the desired output
language to the `src_text`.
- You can see a models's supported language codes in its model card, under target constituents, like in [opus-mt-en-roa](https://huggingface.co/Helsinki-NLP/opus-mt-en-roa).
- Note that if a model is only multilingual on the source side, like `Helsinki-NLP/opus-mt-roa-en`, no language
codes are required.
New multi-lingual models from the [Tatoeba-Challenge repo](https://github.com/Helsinki-NLP/Tatoeba-Challenge)
require 3 character language codes:
```python
>>> from transformers import MarianMTModel, MarianTokenizer
from transformers import MarianMTModel, MarianTokenizer
>>> src_text = [
... ">>fra<< this is a sentence in english that we want to translate to french",
... ">>por<< This should go to portuguese",
... ">>esp<< And this to Spanish",
... ]
# Model trained on multiple source languages → multiple target languages
# Example: multilingual to Arabic (arb)
model_name = "Helsinki-NLP/opus-mt-mul-mul" # Tatoeba Challenge model
tokenizer = MarianTokenizer.from_pretrained(model_name)
model = MarianMTModel.from_pretrained(model_name)
# Prepend the desired output language code (3-letter ISO 639-3)
src_texts = ["arb>> Hello, how are you today?"]
# Tokenize and translate
inputs = tokenizer(src_texts, return_tensors="pt", padding=True, truncation=True)
translated = model.generate(**inputs)
# Decode and print result
translated_texts = tokenizer.batch_decode(translated, skip_special_tokens=True)
print(translated_texts[0])
>>> model_name = "Helsinki-NLP/opus-mt-en-roa"
>>> tokenizer = MarianTokenizer.from_pretrained(model_name)
>>> print(tokenizer.supported_language_codes)
['>>zlm_Latn<<', '>>mfe<<', '>>hat<<', '>>pap<<', '>>ast<<', '>>cat<<', '>>ind<<', '>>glg<<', '>>wln<<', '>>spa<<', '>>fra<<', '>>ron<<', '>>por<<', '>>ita<<', '>>oci<<', '>>arg<<', '>>min<<']
>>> model = MarianMTModel.from_pretrained(model_name)
>>> translated = model.generate(**tokenizer(src_text, return_tensors="pt", padding=True))
>>> [tokenizer.decode(t, skip_special_tokens=True) for t in translated]
["c'est une phrase en anglais que nous voulons traduire en français",
'Isto deve ir para o português.',
'Y esto al español']
```
- Older multilingual models use 2 character language codes.
Here is the code to see all available pretrained models on the hub:
```python
from huggingface_hub import list_models
from transformers import MarianMTModel, MarianTokenizer
# Example: older multilingual model (like en → many)
model_name = "Helsinki-NLP/opus-mt-en-ROMANCE" # English → French, Spanish, Italian, etc.
tokenizer = MarianTokenizer.from_pretrained(model_name)
model = MarianMTModel.from_pretrained(model_name)
# Prepend the 2-letter ISO 639-1 target language code (older format)
src_texts = [">>fr<< Hello, how are you today?"]
# Tokenize and translate
inputs = tokenizer(src_texts, return_tensors="pt", padding=True, truncation=True)
translated = model.generate(**inputs)
# Decode and print result
translated_texts = tokenizer.batch_decode(translated, skip_special_tokens=True)
print(translated_texts[0])
model_list = list_models()
org = "Helsinki-NLP"
model_ids = [x.id for x in model_list if x.id.startswith(org)]
suffix = [x.split("/")[1] for x in model_ids]
old_style_multi_models = [f"{org}/{s}" for s in suffix if s != s.lower()]
```
## Old Style Multi-Lingual Models
These are the old style multi-lingual models ported from the OPUS-MT-Train repo: and the members of each language
group:
```python no-style
['Helsinki-NLP/opus-mt-NORTH_EU-NORTH_EU',

>>> tokenizer = MarianTokenizer.from_pretrained(model_name)
>>> model = MarianMTModel.from_pretrained(model_name)
>>> translated = model.generate(**tokenizer(src_text, return_tensors="pt", padding=True))
>>> tgt_text = [tokenizer.decode(t, skip_special_tokens=True) for t in translated]
["c'est une phrase en anglais que nous voulons traduire en français",
'Isto deve ir para o português.',
'Y esto al español']
```

# PEGASUS-X
[PEGASUS-X](https://huggingface.co/papers/2208.04347) is an encoder-decoder (sequence-to-sequence) transformer model for long-input summarization. It extends the [Pegasus](./pegasus) model with staggered block-local attention, global encoder tokens, and additional pretraining on long text sequences, enabling it to handle inputs of up to 16,000 tokens. PEGASUS-X matches the performance of much larger models while using fewer parameters.

The PEGASUS-X model was proposed in [Investigating Efficiently Extending Transformers for Long Input Summarization](https://huggingface.co/papers/2208.04347) by Jason Phang, Yao Zhao and Peter J. Liu.
The example below demonstrates how to summarize text with [`Pipeline`], [`AutoModel`], and from the command line.
PEGASUS-X (PEGASUS eXtended) extends the PEGASUS models for long input summarization through additional long input pretraining and using staggered block-local attention with global tokens in the encoder.

The abstract from the paper is the following:
```py
import torch
from transformers import pipeline
*While large pretrained Transformer models have proven highly capable at tackling natural language tasks, handling long sequence inputs continues to be a significant challenge. One such task is long input summarization, where inputs are longer than the maximum input context of most pretrained models. Through an extensive set of experiments, we investigate what model architectural changes and pretraining paradigms can most efficiently adapt a pretrained Transformer for long input summarization. We find that a staggered, block-local Transformer with global encoder tokens strikes a good balance of performance and efficiency, and that an additional pretraining phase on long sequences meaningfully improves downstream summarization performance. Based on our findings, we introduce PEGASUS-X, an extension of the PEGASUS model with additional long input pretraining to handle inputs of up to 16K tokens. PEGASUS-X achieves strong performance on long input summarization tasks comparable with much larger models while adding few additional parameters and not requiring model parallelism to train.*

# PerceptionLM
## Overview
The PerceptionLM model was proposed in [PerceptionLM: Open-Access Data and Models for Detailed Visual Understanding](https://ai.meta.com/research/publications/perceptionlm-open-access-data-and-models-for-detailed-visual-understanding/) by Jang Hyun Cho et al. It's a fully open, reproducible model for transparent research in image and video understanding. PLM consists of
a vision encoder with a small scale (<8B parameters) LLM decoder.
The abstract from the paper is the following:
*Vision-language models are integral to computer vision research, yet many high-performing models
remain closed-source, obscuring their data, design and training recipe. The research community
has responded by using distillation from black-box models to label training data, achieving strong
benchmark results, at the cost of measurable scientific progress. However, without knowing the details
of the teacher model and its data sources, scientific progress remains difficult to measure. In this
paper, we study building a Perception Language Model (PLM) in a fully open and reproducible
framework for transparent research in image and video understanding. We analyze standard training
pipelines without distillation from proprietary models and explore large-scale synthetic data to identify
critical data gaps, particularly in detailed video understanding. To bridge these gaps, we release 2.8M
human-labeled instances of fine-grained video question-answer pairs and spatio-temporally grounded
video captions. Additionally, we introduce PLMVideoBench, a suite for evaluating challenging video
understanding tasks focusing on the ability to reason about what”, where”, when”, and how of a
video. We make our work fully reproducible by providing data, training recipes, code & models.*

# SmolLM3
SmolLM3 is a fully open, compact language model designed for efficient deployment while maintaining strong performance. It uses a Transformer decoder architecture with Grouped Query Attention (GQA) to reduce the kv cache, and no RoPE, enabling improved performance on long-context tasks. It is trained using a multi-stage training approach on high-quality public datasets across web, code, and math domains. The model is multilingual and supports very large context lengths. The instruct variant is optimized for reasoning and tool use.

# SuperPoint
[SuperPoint](https://huggingface.co/papers/1712.07629) is the result of self-supervised training of a fully-convolutional network for interest point detection and description. The model is able to detect interest points that are repeatable under homographic transformations and provide a descriptor for each point. Usage on it's own is limited, but it can be used as a feature extractor for other tasks such as homography estimation and image matching.

## Overview
The SuperPoint model was proposed
in [SuperPoint: Self-Supervised Interest Point Detection and Description](https://huggingface.co/papers/1712.07629) by Daniel
DeTone, Tomasz Malisiewicz and Andrew Rabinovich.
This model is the result of a self-supervised training of a fully-convolutional network for interest point detection and
description. The model is able to detect interest points that are repeatable under homographic transformations and
provide a descriptor for each point. The use of the model in its own is limited, but it can be used as a feature
extractor for other tasks such as homography estimation, image matching, etc.
The abstract from the paper is the following:
*This paper presents a self-supervised framework for training interest point detectors and descriptors suitable for a
large number of multiple-view geometry problems in computer vision. As opposed to patch-based neural networks, our
fully-convolutional model operates on full-sized images and jointly computes pixel-level interest point locations and
associated descriptors in one forward pass. We introduce Homographic Adaptation, a multi-scale, multi-homography
approach for boosting interest point detection repeatability and performing cross-domain adaptation (e.g.,
synthetic-to-real). Our model, when trained on the MS-COCO generic image dataset using Homographic Adaptation, is able
to repeatedly detect a much richer set of interest points than the initial pre-adapted deep model and any other
traditional corner detector. The final system gives rise to state-of-the-art homography estimation results on HPatches
when compared to LIFT, SIFT and ORB.*

## Usage tips
Here is a quick example of using the model to detect interest points in an image:
The example below demonstrates how to detect interest points in an image with the [`AutoModel`] class.
<hfoptions id="usage">
<hfoption id="AutoModel">
```py
```python
from transformers import AutoImageProcessor, SuperPointForKeypointDetection
import torch
from PIL import Image
@ -51,76 +64,67 @@ processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint"
model = SuperPointForKeypointDetection.from_pretrained("magic-leap-community/superpoint")
inputs = processor(image, return_tensors="pt")
with torch.no_grad():
outputs = model(**inputs)
# Post-process to get keypoints, scores, and descriptors
image_size = (image.height, image.width)
processed_outputs = processor.post_process_keypoint_detection(outputs, [image_size])
outputs = model(**inputs)
```
</hfoption>
</hfoptions>
The outputs contain the list of keypoint coordinates with their respective score and description (a 256-long vector).
## Notes
You can also feed multiple images to the model. Due to the nature of SuperPoint, to output a dynamic number of keypoints,
you will need to use the mask attribute to retrieve the respective information :
- SuperPoint outputs a dynamic number of keypoints per image, which makes it suitable for tasks requiring variable-length feature representations.
```python
from transformers import AutoImageProcessor, SuperPointForKeypointDetection
import torch
from PIL import Image
import requests
```py
from transformers import AutoImageProcessor, SuperPointForKeypointDetection
import torch
from PIL import Image
import requests
processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint")
model = SuperPointForKeypointDetection.from_pretrained("magic-leap-community/superpoint")
url_image_1 = "http://images.cocodataset.org/val2017/000000039769.jpg"
image_1 = Image.open(requests.get(url_image_1, stream=True).raw)
url_image_2 = "http://images.cocodataset.org/test-stuff2017/000000000568.jpg"
image_2 = Image.open(requests.get(url_image_2, stream=True).raw)
images = [image_1, image_2]
inputs = processor(images, return_tensors="pt")
# Example of handling dynamic keypoint output
outputs = model(**inputs)
keypoints = outputs.keypoints # Shape varies per image
scores = outputs.scores # Confidence scores for each keypoint
descriptors = outputs.descriptors # 256-dimensional descriptors
mask = outputs.mask # Value of 1 corresponds to a keypoint detection
```
url_image_1 = "http://images.cocodataset.org/val2017/000000039769.jpg"
image_1 = Image.open(requests.get(url_image_1, stream=True).raw)
url_image_2 = "http://images.cocodataset.org/test-stuff2017/000000000568.jpg"
image_2 = Image.open(requests.get(url_image_2, stream=True).raw)
- The model provides both keypoint coordinates and their corresponding descriptors (256-dimensional vectors) in a single forward pass.
- For batch processing with multiple images, you need to use the mask attribute to retrieve the respective information for each image. You can use the `post_process_keypoint_detection` from the `SuperPointImageProcessor` to retrieve the each image information.
images = [image_1, image_2]
```py
# Batch processing example
images = [image1, image2, image3]
inputs = processor(images, return_tensors="pt")
outputs = model(**inputs)
image_sizes = [(img.height, img.width) for img in images]
processed_outputs = processor.post_process_keypoint_detection(outputs, image_sizes)
```
processor = AutoImageProcessor.from_pretrained("magic-leap-community/superpoint")
model = SuperPointForKeypointDetection.from_pretrained("magic-leap-community/superpoint")
- You can then print the keypoints on the image of your choice to visualize the result:
```py

# Switch Transformers
## Overview
[Switch Transformers](https://huggingface.co/papers/2101.03961) is a sparse T5 model where the MLP layer is replaced by a Mixture-of-Experts (MoE). A routing mechanism associates each token with an expert and each expert is a dense MLP. Sparsity enables better scaling and the routing mechanism allows the model to select relevant weights on the fly which increases model capacity.
The SwitchTransformers model was proposed in [Switch Transformers: Scaling to Trillion Parameter Models with Simple and Efficient Sparsity](https://huggingface.co/papers/2101.03961) by William Fedus, Barret Zoph, Noam Shazeer.
You can find all the original Switch Transformers checkpoints under the [Switch Transformer](https://huggingface.co/collections/google/switch-transformers-release-6548c35c6507968374b56d1f) collection.
The Switch Transformer model uses a sparse T5 encoder-decoder architecture, where the MLP are replaced by a Mixture of Experts (MoE). A routing mechanism (top 1 in this case) associates each token to one of the expert, where each expert is a dense MLP. While switch transformers have a lot more weights than their equivalent dense models, the sparsity allows better scaling and better finetuning performance at scale.
During a forward pass, only a fraction of the weights are used. The routing mechanism allows the model to select relevant weights on the fly which increases the model capacity without increasing the number of operations.

*In deep learning, models typically reuse the same parameters for all inputs. Mixture of Experts (MoE) defies this and instead selects different parameters for each incoming example. The result is a sparsely-activated model -- with outrageous numbers of parameters -- but a constant computational cost. However, despite several notable successes of MoE, widespread adoption has been hindered by complexity, communication costs and training instability -- we address these with the Switch Transformer. We simplify the MoE routing algorithm and design intuitive improved models with reduced communication and computational costs. Our proposed training techniques help wrangle the instabilities and we show large sparse models may be trained, for the first time, with lower precision (bfloat16) formats. We design models based off T5-Base and T5-Large to obtain up to 7x increases in pre-training speed with the same computational resources. These improvements extend into multilingual settings where we measure gains over the mT5-Base version across all 101 languages. Finally, we advance the current scale of language models by pre-training up to trillion parameter models on the "Colossal Clean Crawled Corpus" and achieve a 4x speedup over the T5-XXL model.*
The example below demonstrates how to predict the masked token with [`Pipeline`], [`AutoModel`], and from the command line.

## Usage tips
```python
import torch
from transformers import pipeline
- SwitchTransformers uses the [`T5Tokenizer`], which can be loaded directly from each model's repository.
- The released weights are pretrained on English [Masked Language Modeling](https://moon-ci-docs.huggingface.co/docs/transformers/pr_19323/en/glossary#general-terms) task, and should be finetuned.
pipeline = pipeline(
task="text2text-generation",
model="google/switch-base-8",
torch_dtype=torch.float16,
device=0
)
print(pipeline("The capital of France is <extra_id_0>."))
```
</hfoption>
<hfoption id="AutoModel">
```python
import torch
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("google/switch-base-8")
model = AutoModelForSeq2SeqLM.from_pretrained("google/switch-base-8", device_map="auto", torch_dtype=torch.float16)
input_text = "The capital of France is <extra_id_0>."
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(0)
outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```
</hfoption>
<hfoption id="transformers CLI">
```bash
echo -e "The capital of France is <extra_id_0>." | transformers run --task text2text-generation --model google/switch-base-8 --device 0
# [{'generated_text': 'Paris.'}]
```
</hfoption>
</hfoptions>
Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [bitsandbytes](../quantization/bitsandbytes/) to only quantize the weights to 8-bits.
```py
# pip install bitsandbytes
import torch
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer, BitsAndBytesConfig
tokenizer = AutoTokenizer.from_pretrained("google/switch-base-8")
quantization_config = BitsAndBytesConfig(load_in_8bit=True)
model = AutoModelForSeq2SeqLM.from_pretrained("google/switch-base-8", device_map="auto", quantization_config=quantization_config)
input_text = "The capital of France is <extra_id_0>."
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(0)
outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))

# T5Gemma
T5Gemma (aka encoder-decoder Gemma) was proposed in a [research paper](https://arxiv.org/abs/2504.06225) by Google. It is a family of encoder-decoder large language models, developed by adapting pretrained decoder-only models into encoder-decoder. T5Gemma includes pretrained and instruction-tuned variants. The architecture is based on transformer encoder-decoder design following T5, with improvements from Gemma 2: GQA, RoPE, GeGLU activation, RMSNorm, and interleaved local/global attention.
T5Gemma has two groups of model sizes: 1) [Gemma 2](https://ai.google.dev/gemma/docs/core/model_card_2) sizes (2B-2B, 9B-2B, and 9B-9B), which are based on the offical Gemma 2 models (2B and 9B); and 2) [T5](https://arxiv.org/abs/1910.10683) sizes (Small, Base, Large, and XL), where are pretrained under the Gemma 2 framework following T5 configuration. In addition, we also provide a model at ML size (medium large, ~2B in total), which is in-between T5 Large and T5 XL.
The pretrained varaints are trained with two objectives: prefix language modeling with knowledge distillation (PrefixLM) and UL2, separately. We release both variants for each model size. The instruction-turned varaints was post-trained with supervised fine-tuning and reinforcement learning.

# ViTPose
[ViTPose](https://huggingface.co/papers/2204.12484) is a vision transformer-based model for keypoint (pose) estimation. It uses a simple, non-hierarchical [ViT](./vit) backbone and a lightweight decoder head. This architecture simplifies model design, takes advantage of transformer scalability, and can be adapted to different training strategies.

[ViTPose++](https://huggingface.co/papers/2212.04246) improves on ViTPose by incorporating a mixture-of-experts (MoE) module in the backbone and using more diverse pretraining data.
## Overview
The ViTPose model was proposed in [ViTPose: Simple Vision Transformer Baselines for Human Pose Estimation](https://huggingface.co/papers/2204.12484) by Yufei Xu, Jing Zhang, Qiming Zhang, Dacheng Tao. ViTPose employs a standard, non-hierarchical [Vision Transformer](vit) as backbone for the task of keypoint estimation. A simple decoder head is added on top to predict the heatmaps from a given image. Despite its simplicity, the model gets state-of-the-art results on the challenging MS COCO Keypoint Detection benchmark. The model was further improved in [ViTPose++: Vision Transformer for Generic Body Pose Estimation](https://huggingface.co/papers/2212.04246) where the authors employ
a mixture-of-experts (MoE) module in the ViT backbone along with pre-training on more data, which further enhances the performance.
The abstract from the paper is the following:
*Although no specific domain knowledge is considered in the design, plain vision transformers have shown excellent performance in visual recognition tasks. However, little effort has been made to reveal the potential of such simple structures for pose estimation tasks. In this paper, we show the surprisingly good capabilities of plain vision transformers for pose estimation from various aspects, namely simplicity in model structure, scalability in model size, flexibility in training paradigm, and transferability of knowledge between models, through a simple baseline model called ViTPose. Specifically, ViTPose employs plain and non-hierarchical vision transformers as backbones to extract features for a given person instance and a lightweight decoder for pose estimation. It can be scaled up from 100M to 1B parameters by taking the advantages of the scalable model capacity and high parallelism of transformers, setting a new Pareto front between throughput and performance. Besides, ViTPose is very flexible regarding the attention type, input resolution, pre-training and finetuning strategy, as well as dealing with multiple pose tasks. We also empirically demonstrate that the knowledge of large ViTPose models can be easily transferred to small ones via a simple knowledge token. Experimental results show that our basic ViTPose model outperforms representative methods on the challenging MS COCO Keypoint Detection benchmark, while the largest model sets a new state-of-the-art.*

The example below demonstrates pose estimation with the [`VitPoseForPoseEstimation`] class.
This model was contributed by [nielsr](https://huggingface.co/nielsr) and [sangbumchoi](https://github.com/SangbumChoi).
The original code can be found [here](https://github.com/ViTAE-Transformer/ViTPose).
## Usage Tips
ViTPose is a so-called top-down keypoint detection model. This means that one first uses an object detector, like [RT-DETR](rt_detr.md), to detect people (or other instances) in an image. Next, ViTPose takes the cropped images as input and predicts the keypoints for each of them.

### ViTPose++ models
The best [checkpoints](https://huggingface.co/collections/usyd-community/vitpose-677fcfd0a0b2b5c8f79c4335) are those of the [ViTPose++ paper](https://huggingface.co/papers/2212.04246). ViTPose++ models employ a so-called [Mixture-of-Experts (MoE)](https://huggingface.co/blog/moe) architecture for the ViT backbone, resulting in better performance.
The ViTPose+ checkpoints use 6 experts, hence 6 different dataset indices can be passed.
An overview of the various dataset indices is provided below:
- 0: [COCO validation 2017](https://cocodataset.org/#overview) dataset, using an object detector that gets 56 AP on the "person" class
- 1: [AiC](https://github.com/fabbrimatteo/AiC-Dataset) dataset
- 2: [MPII](https://www.mpi-inf.mpg.de/departments/computer-vision-and-machine-learning/software-and-datasets/mpii-human-pose-dataset) dataset
- 3: [AP-10K](https://github.com/AlexTheBad/AP-10K) dataset
- 4: [APT-36K](https://github.com/pandorgan/APT-36K) dataset
- 5: [COCO-WholeBody](https://github.com/jin-s13/COCO-WholeBody) dataset
Pass the `dataset_index` argument in the forward of the model to indicate which experts to use for each example in the batch. Example usage is shown below:
```python
image_processor = AutoProcessor.from_pretrained("usyd-community/vitpose-plus-base")
model = VitPoseForPoseEstimation.from_pretrained("usyd-community/vitpose-plus-base", device=device)
inputs = image_processor(image, boxes=[person_boxes], return_tensors="pt").to(device)
dataset_index = torch.tensor([0], device=device) # must be a tensor of shape (batch_size,)
with torch.no_grad():
outputs = model(**inputs, dataset_index=dataset_index)
```

### Visualization
To visualize the various keypoints, one can either leverage the `supervision` [library](https://github.com/roboflow/supervision (requires `pip install supervision`):
```python
import supervision as sv
xy = torch.stack([pose_result['keypoints'] for pose_result in image_pose_result]).cpu().numpy()
scores = torch.stack([pose_result['scores'] for pose_result in image_pose_result]).cpu().numpy()

Alternatively, one can also visualize the keypoints using [OpenCV](https://opencv.org/) (requires `pip install opencv-python`):
Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
```python
import math
import cv2
The example below uses [torchao](../quantization/torchao) to only quantize the weights to int4.

## Notes
- Use [`AutoProcessor`] to automatically prepare bounding box and image inputs.
- ViTPose is a top-down pose estimator. It uses a object detector to detect individuals first before keypoint prediction.
- ViTPose++ has 6 different MoE expert heads (COCO validation `0`, AiC `1`, MPII `2`, AP-10K `3`, APT-36K `4`, COCO-WholeBody `5`) which supports 6 different datasets. Pass a specific value corresponding to the dataset to the `dataset_index` to indicate which expert to use.

If an object defined in both the modular and modeling file from which it inherits, the modular definition has precedence unless for assignments containing the pattern `DOCSTRING`. These variables are typically used in `MODEL_START_DOCSTRING` and `MODEL_INPUT_DOCSTRING` in the modeling files. They are big blocks of docstrings and the linter rewrites the names everywhere. For this reason, assignments containing the `DOCSTRING` variable can use the definition found in the source file without copying the whole docstring, by simply setting the variable to `None` in the modular file.
This is very useful if you need the variable reference somewhere but you don't want to clutter the modular file with docstrings which are always the same.

# Distributed inference
# Tensor parallelism in transformers
When a model doesn't fit on a single GPU, distributed inference with [tensor parallelism](./perf_train_gpu_many#tensor-parallelism) can help. Tensor parallelism shards a model onto multiple accelerators (CUDA GPU, Intel XPU, etc.) and parallelizes computations such as matrix multiplication. It enables fitting larger model sizes into memory and is faster because each accelerator can process a tensor slice.
However, tensor parallelism adds communication overhead and should be used on single machine setups with multiple accelerators to take advantage of fast intra-node communication. For multi-node training, it may be more efficient to use pipeline or data parallelism depending on your use case.

This guide shows how to enable tensor parallelism with Transformers and different partitioning strategies.
## Using 🤗 transformers
## Partitioning a model
Transformers provides a simple interface to use for tensor parallelism. We provide multiple classes implementing different partitioning
strategies and a simple entrypoint to parallelize `nn.Module` instance. You won't have to interact with this interface directly, everything is done in `PretrainedModel.from_pretrained` method for you. This section will first talk about the partitioning strategies
we support, then the user interface you will be interacting with, and finally it will teach you how to extend it with your own partitioning
strategies.
Transformers supports tensor parallelism if a model has a `tp_plan`. There are two plans to partition a model.
### Partitioning strategies
- The `auto` tensor parallelism plan partitions a model (see the supported models above) based on a predefined configuration.
- You can also manually specify your own partitioning plan and pass it to the `tp_plan` parameter in [`~PreTrainedModel.from_pretrained`].
In transformers, partitioning strategies reside in a class `ParallelInterface` which works like a mapping from string to the strategy implementation.

## Partitioning strategies
All partitioning strategies are defined in the [`ParallelInterface`] class which maps a string to the strategy implementation. You don't need to interact with this class directly since all the strategies are set with `tp_plan` in [`~PreTrainedModel.from_pretrained`], but it is useful for checking what strategies are available.

```
Refer to the table below to learn more about each strategy.
We support the following strategies:
| Strategy | Description |
|---|---|
| `ColwiseParallel` | Column-wise partitioning of weights and biases. |
| `RowwiseParallel` | Row-wise partitioning of weights and biases. Also supports partitioning `nn.Embedding` modules. |
| `SequenceParallel` | Sequence parallel implementation to support `LayerNorm` and `Dropout` layers. Also supports Python implementation of [RMSNorm](https://github.com/facebookresearch/llama/blob/main/llama/model.py#L34). |
| `PackedColwiseParallel` | Variant of `ColwiseParallel` to support packed weights (for example, packing `up_proj` and `gate_proj` together). Refer to the [code](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py#L79-#L108) for more details. |
| `PackedRowwiseParallel` | Variant of `RowwiseParallel` to support packed weights (refer to the [code](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py#L79-#L108) for more details). |
| `GatherParallel` | Gather outputs of the module across devices. |
| `IsolatedParallel` | Used for Experts in Mixture-of-Experts (MoE) layers to isolates module from other devices. |
| `ReplicateParallel` | Replicate modules across all devices to prevent `torch.distributed` APIs from breaking due to a partially sharded model. |
- `ColwiseParallel` - A simple column-wise partitioning, being able to handle both weights and biases, does exactly what we've discussed before.
- `RowwiseParallel` - Again, row-wise partitioning as dicussed before, supports weights and biases, on top of that it also supports `nn.Embedding` modules.
- `SequenceParallel` - Sequence parallel implementation, for support of `LayerNorm` and `Dropout` layers. Also supports Python implementation of `RMSNorm` (see [this](https://github.com/facebookresearch/llama/blob/main/llama/model.py#L34))
- `PackedColwiseParallel` - A variant of column-wise partitioning, however it works on packed weights (i.e. `up_proj` and `gate_proj` being packed together). For more details, see [this comment](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py#L79-#L108)
- `PackedRowwiseParallel` - A variant of row-wise partitioning, works on packed weights, for more details check the comment linked above.
- `GatherParallel` - A very simple class, that only makes the outputs of the module to be gathered across devices.
- `IsolatedParallel` - This is a special case, where we want to *isolate* the module from the rest of the devices (world). This is used for Experts in MoE layers, basically creating Expert parallelism of sorts.
- `ReplicateParallel` - Many `torch.distributed` APIs break if model is partially sharded, so this class is used to replicate the module across all devices.
### Packed strategies
### Sharding a model
Weight packing packs multiple linear layers into a single, bigger layer. Packed strategies, `PackedColwiseParallel` and `PackedRowwiseParallel`, are used to shard packed weights. The more basic `ColwiseParallel` or `RowwiseParallel` will incorrectly shard the packed weights.
We provide two ways to shard a model, first one is to use `auto` tensor parallelism plan, which will automatically shard the model based on our predefined configuration. This requires the model to have predefined tensor parallel plan in transformers.
The example below packs `up_proj` and `gate_proj` into a single `gate_up_proj` module and requires the `PackedRowwiseParallel` strategy to shard `gate_up_proj`.
```python
from transformers import AutoModelForCausalLM
# model_id = "meta-llama/Meta-Llama-3-8B-Instruct" # better for smaller number of GPUs
model_id = "meta-llama/Llama-4-Scout-17B-16E-Instruct" # better to visualize all the possible strategies
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, tp_plan="auto")
print(model._tp_plan)
```
> [!TIP]
> For a list of models that support tensor parallelism, see the [Supported models](#supported-models) section above.
The second way is to manually specify your own partitioning plan.
```python
from transformers import AutoModelForCausalLM
tp_plan = {
"model.layers.*.self_attn.q_proj": "colwise",
"model.layers.*.self_attn.k_proj": "colwise",
"model.layers.*.self_attn.v_proj": "colwise",
"model.layers.*.self_attn.o_proj": "rowwise",
...
}
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, tp_plan=tp_plan)
print(model._tp_plan)
```
You might have noticed that there are some special cases in the `ParallelInterface` mapping, let's now talk about them. This will help you understand their purpose and help with extending to other strategies.
### PackedRowwiseParallel
This class is a special case of `RowwiseParallel`, it's used to shard packed weights. Weight packing is a common technique used in models. It's a technique where we pack multiple linear layers into a single, bigger one.
For example in `Llama4` model, we pack `up_proj` and `gate_proj` into a single `gate_up_proj` module.
```python
class Llama4TextExperts(nn.Module):
...
self.gate_up_proj = nn.Parameter(torch.empty(self.num_experts, self.hidden_size, 2 * self.expert_dim))
```
Batch matrix multiplication can be used in the `forward` pass to compute the output of the `gate_up_proj` module.
Then in forward, we can use batch matrix multiplication to compute the output of the `gate_up_proj` module.
```python
def forward(self, hidden_states):
@ -164,148 +145,185 @@ def forward(self, hidden_states):
gate, up = gate_up.chunk(2, dim=-1) # Split the output into gate and up
```
In this case, we need to use the `PackedRowwiseParallel` strategy to shard the `gate_up_proj` module, as using a simple `RowwiseParallel` will shard the layers wrongly.
> [!TIP]
> Refer to [this comment](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py#L79-#L108) for an visual representation of why `Packed*` needs to be used.

### Local strategies
Local strategies (`local_colwise`, `local_rowwise`, `local_packed_rowwise`) don't use [DTensor](https://docs.pytorch.org/docs/stable/distributed.tensor.html) because it isn't supported for some operations such as [torch.chunk](https://docs.pytorch.org/docs/stable/generated/torch.chunk.html). Instead, local strategies use the basic [torch.Tensor](https://docs.pytorch.org/docs/stable/tensors.html) and performs some of the distributed logic manually.
### `local*` strategies
<!--
You could have noticed that there are `local*` strategies, which use the same layers as `*` strategy, but don't use `DTensor` at all.
This is because `DTensor` is not supported for some of the operations: such as `torch.chunk`. Therefore, sometimes we need to use the `local*` strategies, which use vanilla `torch.Tensor` and do some of the distributed logic manually.

> [!TIP]
> If you are using a custom partitioning strategy, and it's not working with `... is not supported` error, try using the `local*` strategies to see if they work better.

## Custom partitioning strategies
> [!WARNING]
> Manually specifying your own partitiong plan requires a good understanding of the model architecture and how the partitioning strategies interact together. If you are not sure about this, the resulting model can be very slow, even failing or incorrect. Again, refer to the [Ultra-Scale Playbook](https://huggingface.co/spaces/nanotron/ultrascale-playbook?section=tensor_parallelism) which can teach you everything required.
A custom partitioning strategy should inherit from [`TensorParallelLayer`](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py) and implement `partition_tensor`, `_prepare_input_fn` and `_prepare_output_fn`.
### Extending the interface with your own partitioning strategies
Then it needs to be registered in the `ParallelInterface` mapping so the dispatching logic can find it when specified in `tp_plan`.
This is a very advanced topic, which requires a good understanding of distributed collectives and the model architecture.
Your custom partitioning strategy should inherit from `TensorParallelLayer` defined in [integrations/tensor_parallel.py](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/tensor_parallel.py) and implement: `partition_tensor`, `_prepare_input_fn` and `_prepare_output_fn`. Then it should be registered in the `ParallelInterface` mapping, so our dispatching logic can find it when specified in the `tp_plan`.
The example below shows how to implement `ColwiseParallel` with this workflow.
Let's go through this workflow step by step, on an already existing example: `ColwiseParallel`.
1. Inherit from `TensorParallelLayer`. In the `__init__` method, define `input_layouts` and `output_layouts` to describe how the input and output tensors should be placed on devices. The `desired_input_layouts` attribute is used to specify how the input *should* be placed on devices.
1. Inherit from `TensorParallelLayer` and initialization
```python
class ColwiseParallel(TensorParallelLayer):
def __init__(
self,
*,
input_layouts: Optional[Placement] = None, # The input layout coming from the previous layer
output_layouts: Optional[Placement] = None, # The output layout we want to achieve
use_local_output: bool = True, # Whether to use local output or not
use_dtensor=True, # Whether to use DTensor or not
):
self.input_layouts = (input_layouts or Replicate(),) # The input sharding coming from the previous layer
self.output_layouts = (output_layouts or Shard(-1),) # Desired output sharding
self.desired_input_layouts = (Replicate(),) # Desired input sharding, inputs should be replicated across GPUs
self.use_local_output = use_local_output
self.use_dtensor = use_dtensor
```
2. Implement the `partition_tensor`, `_prepare_input_fn` and `_prepare_output_fn` methods.
The `partition_tensor` method partitions the tensor and fills `empty_param` with the partitioned tensor. Use the utility function `get_tensor_shard` to help you get the correct shard of the original parameter for a given rank and `get_packed_weights` to help with packed weights.
```python
def partition_tensor(
```python
class ColwiseParallel(TensorParallelLayer):
def __init__(
self,
param, # Full tensor of the parameter
empty_param, # Empty tensor of the parameter, will be filled with the partitioned tensor
param_type, # Type of the parameter, `bias` or `weight`
param_casting_dtype, # The type to cast the parameter to
to_contiguous, # Whether to convert the tensor to a contiguous memory layout
rank, # The rank of the current device
device_mesh, # The device mesh
) -> nn.Parameter: # Return the partitioned parameter
...
```
*,
input_layouts: Optional[Placement] = None, # The input layout coming from the previous layer
output_layouts: Optional[Placement] = None, # The output layout we want to achieve
use_local_output: bool = True, # Whether to use local output or not
use_dtensor=True, # Whether to use DTensor or not
):
self.input_layouts = (input_layouts or Replicate(),) # The input sharding coming from the previous layer
self.output_layouts = (output_layouts or Shard(-1),) # Desired output sharding
self.desired_input_layouts = (Replicate(),) # Desired input sharding, inputs should be replicated across GPUs
self.use_local_output = use_local_output
self.use_dtensor = use_dtensor
```
The `_prepare_input_fn` and `_prepare_output_fn` methods are used in the [pre-forward](https://docs.pytorch.org/docs/stable/generated/torch.nn.modules.module.register_module_forward_pre_hook.html) and [forward](https://docs.pytorch.org/docs/stable/generated/torch.nn.modules.module.register_module_forward_hook.html) hooks. They redistribute the inputs and outputs to the desired layout as specified in the `__init__`.
In the `__init__` method, we define these attributes, where `input_layouts` and `output_layouts` describing, how the input and output tensors should be placed on the devices. `desired_input_layouts` is used to specify, how the input *SHOULD* be placed on the devices.
```python
def _prepare_input_fn(input_layouts, desired_input_layouts, mod, inputs, device_mesh):
...
# Do some custom logic, cast to DTensor etc.
...
return inputs.redistribute(placements=desired_input_layouts, device_mesh=device_mesh)
def _prepare_output_fn(output_layouts, use_local_output, mod, outputs, device_mesh):
...
# Do some custom logic, cast to DTensor etc.
...
return outputs.redistribute(placements=output_layouts, device_mesh=device_mesh)
```
2a. Implement `partition_tensor` method
3. Register the strategy to [`ParallelInterface`] to enable it for use with `tp_plan`.
```python
def partition_tensor(
self,
param, # Full tensor of the parameter
empty_param, # Empty tensor of the parameter, will be filled with the partitioned tensor
param_type, # Type of the parameter, `bias` or `weight`
param_casting_dtype, # The type to cast the parameter to
to_contiguous, # Whether to convert the tensor to a contiguous memory layout
rank, # The rank of the current device
device_mesh, # The device mesh
) -> nn.Parameter: # Return the partitioned parameter
...
```
```python
from transformers.integrations.tensor_parallel import ParallelInterface
This method is used to partition the tensor, and fill the `empty_param` with the partitioned tensor.
We provide some utility functions to help you with this, such as `get_tensor_shard` which will get you the correct shard of the original parameter for this rank or `get_packed_weights` to help with packed weights.
ParallelInterface.register_strategy("colwise_custom", ColwiseParallel)
tp_plan = {
"model.layers.*.self_attn.q_proj": "colwise_custom",
...
}
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, tp_plan=tp_plan)
```
2b. Implement `_prepare_input_fn` and `_prepare_output_fn` methods
## Benchmarks
These methods are used as [`pre-forward`](https://docs.pytorch.org/docs/stable/generated/torch.nn.modules.module.register_module_forward_pre_hook.html) and [`forward`](https://docs.pytorch.org/docs/stable/generated/torch.nn.modules.module.register_module_forward_hook.html) hooks respectively. Their purpose is to re-distribute the inputs and outputs to the desired layout, passed in the `__init__` method.
Tensor parallelism can considerably speedup inference, especially for inputs with large batch sizes or long sequences.
```python
def _prepare_input_fn(input_layouts, desired_input_layouts, mod, inputs, device_mesh):
...
# Do some custom logic, cast to DTensor etc.
...
return inputs.redistribute(placements=desired_input_layouts, device_mesh=device_mesh)
Refer to the chart below for the expected speedup for a single forward pass on [Llama](./model_doc/llama) with a sequence length of 512.
def _prepare_output_fn(output_layouts, use_local_output, mod, outputs, device_mesh):
...
# Do some custom logic, cast to DTensor etc.
...
return outputs.redistribute(placements=output_layouts, device_mesh=device_mesh)
```
3. Register the strategy
Congratulations! You've implemented your own partitioning strategy. Now, to use it with your own `tp_plan`, you need to register it in the `ParallelInterface` mapping.
```python
from transformers.integrations.tensor_parallel import ParallelInterface
ParallelInterface.register_strategy("colwise_custom", ColwiseParallel)
```
And now you can use it in your `tp_plan` as such:
```python
tp_plan = {
"model.layers.*.self_attn.q_proj": "colwise_custom",
...
}
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, tp_plan=tp_plan)
```
## Full example
Let's go through a full example of inference with tensor parallelism.
```python
import os
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
# enable tensor parallelism
model = AutoModelForCausalLM.from_pretrained(
"meta-llama/Meta-Llama-3-8B-Instruct",
tp_plan="auto",
)
# prepare input tokens
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Meta-Llama-3-8B-Instruct")
prompt = "Can I help"
inputs = tokenizer(prompt, return_tensors="pt").input_ids.to(model.device)
# distributed run
outputs = model(inputs)
```
Launch the inference script above on [torchrun](https://pytorch.org/docs/stable/elastic/run.html) with 4 processes per GPU.
```bash
torchrun --nproc-per-node 4 demo.py
```
You can benefit from considerable speed ups for inference, especially for inputs with large batch size or long sequences.
For a single forward pass on [Llama](./model_doc/llama) with a sequence length of 512 and various batch sizes, you can expect the following speed ups.

## Design implementation
The Transformers tensor parallelism implementation is framework-agnostic, but for specific implementations, we rely on [DeviceMesh](https://docs.pytorch.org/tutorials/recipes/distributed_device_mesh.html) and [DTensor](https://docs.pytorch.org/docs/stable/distributed.tensor.html) from [torch.distributed](https://docs.pytorch.org/tutorials/beginner/dist_overview.html) to provide a simple and extensible interface.
## Tensor parallelism in-depth
Our implementation of tensor parallelism is framework-agnostic in design, but the specific implementations we've developed rely on the torch.distributed package. We heavily utilize abstractions such as `DeviceMesh` or `DTensor` to provide a simple and extensible interface to the user.
### DeviceMesh
Imagine `DeviceMesh` as a multi-dimensional grid of devices that communicate together. Different parallelization strategies require different types of communication patterns, so you can create a `DeviceMesh` with multiple sub-meshes.
Imagine `DeviceMesh` as a multi-dimensional grid of devices that communicate together. Different parallelization strategies require different types of communication patterns, therefore we can create a `DeviceMesh` with multiple submeshes:
```python
from torch.distributed.device_mesh import init_device_mesh
# Create a 1D mesh of 4 GPUs
device_mesh = init_device_mesh("cuda", (4,), mesh_dim_names=["tp"])

Most of the `torch.distributed` defined parallelization strategies can be applied to the mesh itself, or its sub-mesh, and it automatically handles the communication patterns.

### DTensor
`DTensor` (Distributed Tensor) is a tensor subclass that handles the distributed logic on top of the usual tensor operations. Most of the model weights in tensor parallelism are stored as `DTensor`s.
Abbreviation for Distributed Tensor, `DTensor` is a tensor subclass that handles the distributed logic on-top of the usual tensor operations. Most of the model weights in case of tensor parallelism are stored as `DTensor`s (with some exceptions, more on that later).
The most important part of DTensor, that is crucial to understand, is the `placement` attribute. It's an attribute that tells PyTorch how is the tensor placed on the devices of the `DeviceMesh`.
The most important part of DTensor is the `placement` attribute because it tells PyTorch how a tensor is placed on the devices in `DeviceMesh`. The `placement` attribute can take the following values.
It can have the following values:
- `Shard(dimension)` - Indicates how a `DTensor` is sharded across a given dimension, over the `DeviceMesh` it was constructed under. The example below demonstrates how to shard weights over different dimensions for column-wise partitioning.
- `Shard(dimension)` - Annotates that this `DTensor` is sharded across a given dimension, over the `DeviceMesh` it was constructed under. For example, if we would like to shard weights for column-wise partitioning, we would do:
```python
weight = ...
weight = DTensor.from_local(weight, device_mesh["tp"], placements=[Shard(0)]) # Shard across the 1st (column-wise) dimension
bias = ...
bias = DTensor.from_local(bias, device_mesh["tp"], placements=[Shard(-1)]) # Shard across the ONLY dimension
```
```python
weight = ...
weight = DTensor.from_local(weight, device_mesh["tp"], placements=[Shard(0)]) # Shard across the 1st (column-wise) dimension
bias = ...
bias = DTensor.from_local(bias, device_mesh["tp"], placements=[Shard(-1)]) # Shard across the ONLY dimension
```
To give another example, for row-wise partitioning, we would do:
```python
weight = ...
weight = DTensor.from_local(weight, device_mesh["tp"], placements=[Shard(1)]) # Shard across the 2nd (row-wise) dimension
bias = ...
bias = DTensor.from_local(bias, device_mesh["tp"], placements=[Replicate()]) # Replicate bias across all GPUs
```
This example demonstrates how to shard weights over different dimensions for row-wise partitioning.
```python
weight = ...
weight = DTensor.from_local(weight, device_mesh["tp"], placements=[Shard(1)]) # Shard across the 2nd (row-wise) dimension
bias = ...
bias = DTensor.from_local(bias, device_mesh["tp"], placements=[Replicate()]) # Replicate bias across all GPUs
```
- `Replicate()` - Indicates a `DTensor` is replicated across the `DeviceMesh`. It only creates a full copy of the tensor on each device.
```py
bias = ...
bias = DTensor.from_local(bias, device_mesh["tp"], placements=[Replicate()]) # Replicate bias across all GPUs
```
- `Partial()` - Indicates a tensor is pending a reduction operation (not typically relevant for usage in Transformers).
- `Replicate()` - Annotates that this `DTensor` is replicated across the `DeviceMesh`. Very straight-forward, only creates a full copy of the tensor on each device.
- `Partial()` - This placement is mostly of no interest to us, it's used to annotate that this tensor is pending a reduction operation.

Tensor parallelism is effective for training large models that don't fit into the memory of a single GPU. It is also faster and more efficient because each GPU can process its tensor slice in parallel, and it can be combined with other parallelism methods. Like other parallelism methods though, tensor parallelism adds communication overhead between GPUs.
Refer to the [Tensor parallelism](./perf_infer_gpu_multi) guide to learn how to use it for inference.
## Hybrid parallelism
Parallelism methods can be combined to achieve even greater memory savings and more efficiently train models with billions of parameters.

# TPU
TPU (Tensor Processing Unit) is a type of hardware designed to accelerate tensor computations for training and inference. TPUs are generally accessed through Google cloud services, but smaller TPUs are also available for free from [Google Colab](https://colab.research.google.com/notebooks/tpu.ipynb) or [Kaggle](https://www.kaggle.com/docs/tpu).
This guide focuses on training a Keras model for sequence classification on a TPU from Google Colab. Make sure the TPU runtime is enabled by going to **Runtime > Change runtime type** and selecting a TPU.
Run the command below to install the latest version of Transformers and [Datasets](https://huggingface.co/docs/datasets).
```py
!pip install --U transformers datasets
```
Create an instance of [tf.distribute.cluster_resolver.TPUClusterResolver](https://www.tensorflow.org/api_docs/python/tf/distribute/cluster_resolver/TPUClusterResolver), and then connect to the remote cluster and initialize the TPUs.
```py
import tensorflow as tf
resolver = tf.distribute.cluster_resolver.TPUClusterResolver()
tf.config.experimental_connect_to_cluster(resolver)
tf.tpu.experimental.initialize_tpu_system(resolver)
```
There are various distribution strategies for running your model on multiple TPUs. The [tpu.distribute.TPUStrategy](https://www.tensorflow.org/api_docs/python/tf/distribute/TPUStrategy) offers synchronized distributed training.
```py
strategy = tf.distribute.TPUStrategy(resolver)
```
Load and tokenize a dataset - this example uses [CoLA](https://huggingface.co/datasets/nyu-mll/glue/viewer/cola) from the GLUE benchmark - and pad all samples to the maximum length so it is easier to load as an array and to avoid [XLA compilation issues](#xla).
```py
from transformers import AutoTokenizer
from datasets import load_dataset
import numpy as np
dataset = load_dataset("glue", "cola")["train"]
tokenizer = AutoTokenizer.from_pretrained("distilbert-base-cased")
train_data = tokenizer(
dataset["sentence"],
padding="max_length",
truncation=True,
max_length=128,
return_tensors="np",
)
train_data = dict(train_data)
train_labels = np.array(dataset["label"])
```
The model **must** be created inside [Strategy.scope](https://www.tensorflow.org/api_docs/python/tf/distribute/MirroredStrategy#scope) in order to replicate the model layers on each TPU device.
```py
from transformers import TFAutoModelForSequenceClassification
with strategy.scope():
model = TFAutoModelForSequenceClassification.from_pretrained(model_checkpoint)
model.compile(optimizer="adam")
```
TPUs only accept [tf.data.Dataset](https://www.tensorflow.org/api_docs/python/tf/data/Dataset) inputs unlike the Keras [fit](https://keras.io/api/models/model_training_apis/#fit-method) method which accepts a broader range of inputs.
```py
BATCH_SIZE = 8 * strategy.num_replicas_in_sync
tf_dataset = tf.data.Dataset.from_tensor_slices((train_data, train_labels))
tf_dataset = tf_dataset.shuffle(len(tf_dataset))
tf_dataset = tf_dataset.batch(BATCH_SIZE, drop_remainder=True)
```
Finally, call [fit](https://keras.io/api/models/model_training_apis/#fit-method) to start training.
```py
model.fit(tf_dataset)
```
## Large datasets
The dataset created above pads every sample to the maximum length and loads the whole dataset into memory. This may not be possible if you're working with larger datasets. When training on large datasets, you may want to create a [tf.TFRecord](https://www.tensorflow.org/tutorials/load_data/tfrecord) or stream the data.
### tf.TFRecord
[tf.TFRecord](https://www.tensorflow.org/tutorials/load_data/tfrecord) is the standard [tf.data](https://www.tensorflow.org/guide/data) format for storing training data. For very large training jobs, it's worth preprocessing your data and storing it in the `tf.TFRecord` format and building a `tf.data` pipeline on top. Refer to the table below to help you decide whether `tf.TFRecord` is helpful for you.
| pros | cons |
|---|---|
| works on all TPU instances | costs associated with cloud storage |
| supports huge datasets and massive throughput | some data types (images) can take a lot of space to store |
| suitable for training on entire TPU pods | |
| preprocessing is done in advance, maximizing training speed | |
Preprocess and tokenize the dataset before writing it to a `tf.TFRecord` to avoid writing every time the data is loaded.
An exception is made for *train-time augmentations*, because augmentations applied after writing to a `tf.TFRecord` results in the same augmentation for each epoch. Instead, apply augmentations in the `tf.data` pipeline that loads the data.
> [!TIP]
> In practice, you probably won't be able to load the entire dataset in memory. Load a chunk of the dataset at a time and convert it to `TFRecord`, and repeat until the entire dataset is in the `TFRecord` format. Then you can use a list of all the files to create a `TFRecordDataset`. The example below demonstrates a single file for simplicity.
```py
tokenized_data = tokenizer(
dataset["sentence"],
padding="max_length",
truncation=True,
max_length=128,
return_tensors="np",
)
labels = dataset["label"]
with tf.io.TFRecordWriter("dataset.tfrecords") as file_writer:
for i in range(len(labels)):
features = {
"input_ids": tf.train.Feature(
int64_list=tf.train.Int64List(value=tokenized_data["input_ids"][i])
),
"attention_mask": tf.train.Feature(
int64_list=tf.train.Int64List(value=tokenized_data["attention_mask"][i])
),
"labels": tf.train.Feature(
int64_list=tf.train.Int64List(value=[labels[i]])
),
}
features = tf.train.Features(feature=features)
example = tf.train.Example(features=features)
record_bytes = example.SerializeToString()
file_writer.write(record_bytes)
```
Build a [TFRecordDataset](https://www.tensorflow.org/api_docs/python/tf/data/TFRecordDataset) using the saved filename to load it.
```py
def decode_fn(sample):
features = {
"input_ids": tf.io.FixedLenFeature((128,), dtype=tf.int64),
"attention_mask": tf.io.FixedLenFeature((128,), dtype=tf.int64),
"labels": tf.io.FixedLenFeature((1,), dtype=tf.int64),
}
return tf.io.parse_example(sample, features)
# TFRecordDataset can handle gs:// paths
tf_dataset = tf.data.TFRecordDataset(["gs://matt-tf-tpu-tutorial-datasets/cola/dataset.tfrecords"])
tf_dataset = tf_dataset.map(decode_fn)
tf_dataset = tf_dataset.shuffle(len(dataset)).batch(BATCH_SIZE, drop_remainder=True)
tf_dataset = tf_dataset.apply(
tf.data.experimental.assert_cardinality(len(labels) // BATCH_SIZE)
)
```
The dataset can now be passed to the [fit](https://keras.io/api/models/model_training_apis/#fit-method) method.
```py
model.fit(tf_dataset)
```
### Stream from raw data
Data can be stored in its native format and preprocessed in a [tf.data](https://www.tensorflow.org/guide/data) pipeline as the data is loaded. This approach isn't supported for many models with complex tokenization schemes, but some models like BERT are supported because their tokenization can be compiled. Refer to the table below to help you decide whether this approach is helpful for you.
| pros | cons |
|---|---|
| suitable for highly compressed big data in native format (images, audio) | requires writing a full preprocessing pipeline |
| convenient if raw data is available in a public cloud bucket | complex preprocessing on-the-fly can hurt throughput |
| works on all TPU instances if data is stored in Google Cloud | must place data in cloud storage if not already there |
| | not as suitable for text data because writing a tokenization pipeline is hard (use `TFRecord` for text) |
The example below demonstrates streaming data for an image model.
Load an image dataset and get a list of the underlying image file paths and labels.
```py
from datasets import load_dataset
image_dataset = load_dataset("beans", split="train")
filenames = image_dataset["image_file_path"]
labels = image_dataset["labels"]
```
Convert the local filenames in the dataset into `gs://` paths in Google Cloud Storage.
```py
# strip everything but the category directory and filenames
base_filenames = ['/'.join(filename.split('/')[-2:]) for filename in filenames]
# prepend the Google Cloud base path to everything instead
gs_paths = ["gs://matt-tf-tpu-tutorial-datasets/beans/"+filename for filename in base_filenames]
# create tf_dataset
tf_dataset = tf.data.Dataset.from_tensor_slices(
{"filename": gs_paths, "labels": labels}
)
tf_dataset = tf_dataset.shuffle(len(tf_dataset))
```
Transformers preprocessing classes like [`AutoImageProcessor`] are framework-agnostic and can't be compiled into a pipeline by `tf.data`. To get around this, get the normalization values (`mean` and `std`) from the [`AutoImageProcessor`] and use them in the `tf.data` pipeline.
```py
from transformers import AutoImageProcessor
processor = AutoImageProcessor.from_pretrained("google/vit-base-patch16-224")
image_size = (processor.size["height"], processor.size["width"])
image_mean = processor.image_mean
image_std = processor.image_std
```
Use these normalization values to create a function to load and preprocess the images.
```py
BATCH_SIZE = 8 * strategy.num_replicas_in_sync
def decode_fn(sample):
image_data = tf.io.read_file(sample["filename"])
image = tf.io.decode_jpeg(image_data, channels=3)
image = tf.image.resize(image, image_size)
array = tf.cast(image, tf.float32)
array /= 255.0
array = (array - image_mean) / image_std
array = tf.transpose(array, perm=[2, 0, 1])
return {"pixel_values": array, "labels": sample["labels"]}
tf_dataset = tf_dataset.map(decode_fn)
tf_dataset = tf_dataset.batch(BATCH_SIZE, drop_remainder=True)
print(tf_dataset.element_spec)
```
The dataset can now be passed to the [fit](https://keras.io/api/models/model_training_apis/#fit-method) method.
```py
from transformers import TFAutoModelForImageClassification
with strategy.scope():
model = TFAutoModelForImageClassification.from_pretrained(image_model_checkpoint)
model.compile(optimizer="adam")
model.fit(tf_dataset)
```
### Stream with prepare_tf_dataset
[`~TFPreTrainedModel.prepare_tf_dataset`] creates a `tf.data` pipeline that loads samples from [tf.data.Dataset](https://www.tensorflow.org/api_docs/python/tf/data/Dataset). The pipeline uses [tf.numpy_function]() or [`~datasets.Dataset.from_generator`], which can't be compiled by TensorFlow, to access the underlying `tf.data.Dataset`. It also won't work on a Colab TPU or TPU Nodes because the pipeline streams data from a local disk. Refer to the table below to help you decide whether this approach is helpful for you.
| pros | cons |
|---|---|
| simple code | only works on TPU VM |
| same approach on TPU/GPU | data must be available as a Hugging Face Dataset |
| dataset doesn't have to fit in memory | data must fit on local storage |
| supports variable padding | data loading may be a bottleneck on a big TPU pod slice |
[`~TFPreTrainedModel.prepare_tf_dataset`] only works on [TPU VM](#tpu-types). Add the tokenizer output as columns in the dataset since the dataset is stored on disk, which means it can handle data larger than the available memory. Use [`~TFPreTrainedModel.prepare_tf_dataset`] to stream data from the dataset by wrapping it with a `tf.data` pipeline.
```py
def tokenize_function(examples):
return tokenizer(
examples["sentence"], padding="max_length", truncation=True, max_length=128
)
# add the tokenizer output to the dataset as new columns
dataset = dataset.map(tokenize_function)
# prepare_tf_dataset() chooses columns that match the models input names
tf_dataset = model.prepare_tf_dataset(
dataset, batch_size=BATCH_SIZE, shuffle=True, tokenizer=tokenizer
)
```
The dataset can now be passed to the [fit](https://keras.io/api/models/model_training_apis/#fit-method) method.
```py
from transformers import AutoTokenizer, TFAutoModelForSequenceClassification
with strategy.scope():
model = TFAutoModelForSequenceClassification.from_pretrained(model_checkpoint)
model.compile(optimizer="adam")
model.fit(tf_dataset)
```
## TPU types
There are two types of TPUs, a TPU Node and a TPU VM.
A TPU Node indirectly accesses a remote TPU. It requires a separate VM to initialize your network and data pipeline, and then forwards it to the remote node. Google Colab TPUs are an example of a TPU Node. You can't use local data because the TPU is remotely located, and data must be stored in Google Cloud Storage where the data pipeline can access it.
TPU VM are connected directly to the machine the TPU is located on, and they are generally easier to work with, especially when it comes to your data pipeline.
> [!TIP]
> We recommend avoiding TPU Nodes if possible because it is more difficult to debug than TPU VMs. TPU Nodes may also be unsupported in the future and become a legacy access method.
A single TPU (v2-8, v3-8, v4-8) runs 8 replicas. TPUs can exist in **pods** which run hundreds or even thousands of replicas simultaneously. When you only use a portion of a pod, it is referred to as a **pod slice**. On Google Colab, you'll typically get a single v2-8 TPU.
## XLA
[XLA](https://openxla.org/xla) is a linear algebra compiler for high-performance execution and it is used by default to improve performance on TPUs.
Before executing your code on a TPU, it's a good idea to try it first on a CPU or GPU because it is easier to debug. You can train for a few steps to make sure the model and data pipeline work as expected. Set `jit_compile=True` in the [compile](https://keras.io/api/models/model_training_apis/#compile-method) method to enable XLA compilation (but remember to remove this line of code before running on a TPU).
The section below outlines three rules for making your code XLA-compatible. Transformers enforce the first two rules for models and loss functions by default, but don't forget about them if you're writing your own models and loss functions.
### Data dependent conditionals
Any `if` statements cannot depend on values inside a [tf.Tensor](https://www.tensorflow.org/api_docs/python/tf/Tensor). The code below can't be compiled by XLA.
```py
if tf.reduce_sum(tensor) > 10:
tensor = tensor / 2.0
```
To compile with XLA, use [tf.cond](https://www.tensorflow.org/api_docs/python/tf/cond) or remove the conditional and use indicator variables instead as shown below.
```py
sum_over_10 = tf.cast(tf.reduce_sum(tensor) > 10, tf.float32)
tensor = tensor / (1.0 + sum_over_10)
```
### Data dependent shapes
The shape of a [tf.Tensor](https://www.tensorflow.org/api_docs/python/tf/Tensor) cannot depend on their values. For example, [tf.unique](https://www.tensorflow.org/api_docs/python/tf/unique) can't be compiled because it returns a tensor containing an instance of each unique value in the input. The shape of this output depends on how repetitive the input [tf.Tensor](https://www.tensorflow.org/api_docs/python/tf/Tensor) is.
This is an issue during **label masking**, where labels are set to a negative value to indicate they should be ignored when computing the loss. The code below can't be compiled by XLA because the shape of `masked_outputs` and `masked_labels` depend on how many positions are masked.
```py
label_mask = labels >= 0
masked_outputs = outputs[label_mask]
masked_labels = labels[label_mask]
loss = compute_loss(masked_outputs, masked_labels)
mean_loss = torch.mean(loss)
```
To compile with XLA, avoid the data-dependent shapes by computing the loss for every position and zeroing out the masked positions in both the numerator and denominator when calculating the mean. Convert `tf.bool` to `tf.float32` as an indicator variable to make your code XLA-compatible.
```py
label_mask = tf.cast(labels >= 0, tf.float32)
loss = compute_loss(outputs, labels)
loss = loss * label_mask
mean_loss = tf.reduce_sum(loss) / tf.reduce_sum(label_mask)
```
### Recompile different input shapes
XLA recompiles your model if input shapes are variable which create huge performance problems. It is especially common in text models because input texts have variable lengths after tokenization.
> [!WARNING]
> Execessive padding can also severely slow down training because requires more compute and memory to process.
To avoid different shapes, use padding to pad all your inputs to the same length and use an `attention_mask`. Try padding batches of samples to a multiple of 32 or 64 tokens. Use the parameters `padding="max_length"`, `padding="longest"`, or `pad_to_multiple_of` to help with padding. This often increases the number of tokens by a small amount, but it significantly reduces the number of unique input shapes because every input shape is a multiple of 32 or 64. Fewer unique input shapes requires fewer recompilation.

# Serving
Transformer models can be efficiently deployed using libraries such as vLLM, Text Generation Inference (TGI), and others. These libraries are designed for production-grade user-facing services, and can scale to multiple servers and millions of concurrent users.
You can also serve transformer models easily using the `transformers serve` CLI. This is ideal for experimentation purposes, or to run models locally for personal and private use.
Transformer models can be served for inference with specialized libraries such as Text Generation Inference (TGI) and vLLM. These libraries are specifically designed to optimize performance with LLMs and include many unique optimization features that may not be included in Transformers.

## Serve CLI
> [!WARNING]
> This section is experimental and subject to change in future versions
<!-- TODO: LLMs -> models, after we add audio/image input/output support -->
You can serve LLMs supported by `transformers` with the `transformers serve` CLI. It spawns a local server that offers a chat Completions API compatible with the OpenAI SDK, which is the _de facto_ standard for LLM conversations. This way, you can use the server from many third party applications, or test it using the `transformers chat` CLI ([docs](conversations.md#chat-cli)).
To launch a server, simply use the `transformers serve` CLI command:
```shell
transformers serve
```
The simplest way to interact with the server is through our `transformers chat` CLI
```shell
transformers chat localhost:8000 --model-name-or-path Qwen/Qwen3-4B
```
or by sending an HTTP request with `cURL`, e.g.
```shell
curl -X POST http://localhost:8000/v1/chat/completions -H "Content-Type: application/json" -d '{"messages": [{"role": "system", "content": "hello"}], "temperature": 0.9, "max_tokens": 1000, "stream": true, "model": "Qwen/Qwen2.5-0.5B-Instruct"}'
```
from which you'll receive multiple chunks in the Completions API format
```shell
data: {"object": "chat.completion.chunk", "id": "req_0", "created": 1751377863, "model": "Qwen/Qwen2.5-0.5B-Instruct", "system_fingerprint": "", "choices": [{"delta": {"role": "assistant", "content": "", "tool_call_id": null, "tool_calls": null}, "index": 0, "finish_reason": null, "logprobs": null}]}
data: {"object": "chat.completion.chunk", "id": "req_0", "created": 1751377863, "model": "Qwen/Qwen2.5-0.5B-Instruct", "system_fingerprint": "", "choices": [{"delta": {"role": "assistant", "content": "", "tool_call_id": null, "tool_calls": null}, "index": 0, "finish_reason": null, "logprobs": null}]}
(...)
```
The server is also an MCP client, so it can interact with MCP tools in agentic use cases. This, of course, requires the use of an LLM that is designed to use tools.
> [!TIP]
> At the moment, MCP tool usage in `transformers` is limited to the `qwen` family of models.
<!-- TODO: example with a minimal python example, and explain that it is possible to pass a full generation config in the request -->
### Usage example 1: apps with local requests (feat. Jan)
This example shows how to use `transformers serve` as a local LLM provider for the [Jan](https://jan.ai/) app. Jan is a ChatGPT-alternative graphical interface, fully running on your machine. The requests to `transformers serve` come directly from the local app -- while this section focuses on Jan, you can extrapolate some instructions to other apps that make local requests.
To connect `transformers serve` with Jan, you'll need to set up a new model provider ("Settings" > "Model Providers"). Click on "Add Provider", and set a new name. In your new model provider page, all you need to set is the "Base URL" to the following pattern:
```shell
http://[host]:[port]/v1
```
where `host` and `port` are the `transformers serve` CLI parameters (`localhost:8000` by default). After setting this up, you should be able to see some models in the "Models" section, hitting "Refresh". Make sure you add some text in the "API key" text field too -- this data is not actually used, but the field can't be empty. Your custom model provider page should look like this:
<h3 align="center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/transformers_serve_jan_model_providers.png"/>
</h3>
You are now ready to chat!
> [!TIP]
> You can add any `transformers`-compatible model to Jan through `transformers serve`. In the custom model provider you created, click on the "+" button in the "Models" section and add its Hub repository name, e.g. `Qwen/Qwen3-4B`.
To conclude this example, let's look into a more advanced use-case. If you have a beefy machine to serve models with, but prefer using Jan on a different device, you need to add port forwarding. If you have `ssh` access from your Jan machine into your server, this can be accomplished by typing the following to your Jan machine's terminal
```
ssh -N -f -L 8000:localhost:8000 your_server_account@your_server_IP -p port_to_ssh_into_your_server
```
Port forwarding is not Jan-specific: you can use it to connect `transformers serve` running in a different machine with an app of your choice.
### Usage example 2: apps with external requests (feat. Cursor)
This example shows how to use `transformers serve` as a local LLM provider for [Cursor](https://cursor.com/), the popular IDE. Unlike in the previous example, requests to `transformers serve` will come from an external IP (Cursor's server IPs), which requires some additional setup. Furthermore, some of Cursor's requests require [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/CORS), which is disabled by default for security reasons.
To launch our server with CORS enabled, run
```shell
transformers serve --enable-cors
```
We'll also need to expose our server to external IPs. A potential solution is to use [`ngrok`](https://ngrok.com/), which has a permissive free tier. After setting up your `ngrok` account and authenticating on your server machine, you run
```shell
ngrok http [port]
```
where `port` is the port used by `transformers serve` (`8000` by default). On the terminal where you launched `ngrok`, you'll see an https address in the "Forwarding" row, as in the image below. This is the address to send requests to.
<h3 align="center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/transformers_serve_ngrok.png"/>
</h3>
We're now ready to set things up on the app side! In Cursor, while we can't set a new provider, we can change the endpoint for OpenAI requests in the model selection settings. First, navigate to "Settings" > "Cursor Settings", "Models" tab, and expand the "API Keys" collapsible. To set our `transformers serve` endpoint, follow this order:
1. Unselect ALL models in the list above (e.g. `gpt4`, ...);
2. Add and select the model you want to use (e.g. `Qwen/Qwen3-4B`)
3. Add some random text to OpenAI API Key. This field won't be used, but it cant be empty;
4. Add the https address from `ngrok` to the "Override OpenAI Base URL" field, appending `/v1` to the address (i.e. `https://(...).ngrok-free.app/v1`);
5. Hit "Verify".
After you follow these steps, your "Models" tab should look like the image below. Your server should also have received a few requests from the verification step.
<h3 align="center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/transformers_serve_cursor.png"/>
</h3>
You are now ready to use your local model in Cursor! For instance, if you toggle the AI Pane, you can select the model you added and ask it questions about your local files.
<h3 align="center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/transformers_serve_cursor_chat.png"/>
</h3>
### Usage example 3: `tiny-agents` CLI and MCP Tools
To showcase the use of MCP tools, let's see how to integrate the `transformers serve` server with the [`tiny-agents`](https://huggingface.co/blog/python-tiny-agents) CLI.
> [!TIP]
> Many Hugging Face Spaces can be used as MCP servers, as in this example. You can find all compatible Spaces [here](https://huggingface.co/spaces?filter=mcp-server).
The first step to use MCP tools is to let the model know which tools are available. As an example, let's consider a `tiny-agents` configuration file with a reference to an [image generation MCP server](https://evalstate-flux1-schnell.hf.space/).
```json
{
"model": "Menlo/Jan-nano",
"endpointUrl": "http://localhost:8000",
"servers": [
{
"type": "sse",
"url": "https://evalstate-flux1-schnell.hf.space/gradio_api/mcp/sse"
}
]
}
```
You can then launch your `tiny-agents` chat interface with the following command.
```bash
tiny-agents run path/to/your/config.json
```
If you have `transformers serve` running in the background, you're ready to use MCP tools from a local model! For instance, here's the example of a chat session with `tiny-agents`:
```bash
Agent loaded with 1 tools:
• flux1_schnell_infer
» Generate an image of a cat on the moon
<Tool req_0_tool_call>flux1_schnell_infer {"prompt": "a cat on the moon", "seed": 42, "randomize_seed": true, "width": 1024, "height": 1024, "num_inference_steps": 4}
Tool req_0_tool_call
[Binary Content: Image image/webp, 57732 bytes]

# XLA
[[open-in-colab]]
[Accelerated Linear Algebra (XLA)](https://openxla.org/xla) is a linear algebra compiler that optimizes model runtime across different hardware and frameworks.
This guide will look specifically at how to accelerate *TensorFlow* models with XLA.
## TensorFlow
XLA can potentially accelerate a TensorFlow model without making any source code changes. It is already packaged with the TensorFlow library, and it is triggered with `jit_compile` in any graph creating function such as [tf.function](https://www.tensorflow.org/api_docs/python/tf/function).
If you're using Keras methods like [fit](https://keras.io/api/models/model_training_apis/#fit-method) and [predict](https://keras.io/api/models/model_training_apis/#predict-method), enable XLA by passing `jit_compile=True` to [compile](https://keras.io/api/models/model_training_apis/#compile-method).
```py
model.compile(jit_compile=True)
```
XLA can be used to accelerate any arbitrary [tf.function](https://www.tensorflow.org/api_docs/python/tf/function).
Models with a TensorFlow implementation like [GPT2](./model_doc/gpt2), [T5](./model_doc/t5), [OPT](./model_doc/opt), and [Whisper](./model_doc/whisper) are XLA compatible. The speed up depends on a model, but in general, TensorFlow models in Transformers get a ~100x speed up.
### Functions
A typical forward pass in a TensorFlow model is shown below. To run a forward pass with XLA, wrap the model with [tf.function](https://www.tensorflow.org/api_docs/python/tf/function) and set `jit_compile=True`.
```diff
import tensorflow as tf
model = tf.keras.Sequential(
[tf.keras.layers.Dense(10, input_shape=(10,), activation="relu"), tf.keras.layers.Dense(5, activation="softmax")]
)
# Generate random inputs for the model.
batch_size = 16
input_vector_dim = 10
random_inputs = tf.random.normal((batch_size, input_vector_dim))
# Run a forward pass.
- _ = model(random_inputs)
+ xla_fn = tf.function(model, jit_compile=True)
+ _ = xla_fn(random_inputs)
```
The default `call` function of the model is used to compile the XLA graph. But if there's any other model function you want to compile with XLA, wrap them with [tf.function](https://www.tensorflow.org/api_docs/python/tf/function).
```py
my_xla_fn = tf.function(model.my_xla_fn, jit_compile=True)
```
### Text generation
You could also compile other model functions with XLA. For example, enable XLA for text generation by wrapping [`~TFGenerationMixin.generate`] with [tf.function](https://www.tensorflow.org/api_docs/python/tf/function).
```py
import tensorflow as tf
from transformers import AutoTokenizer, TFAutoModelForCausalLM
# Will error if the minimal version of Transformers is not installed.
from transformers.utils import check_min_version
check_min_version("4.21.0")
tokenizer = AutoTokenizer.from_pretrained("openai-community/gpt2", padding_side="left", pad_token="</s>")
model = TFAutoModelForCausalLM.from_pretrained("openai-community/gpt2")
input_string = ["TensorFlow is"]
xla_generate = tf.function(model.generate, jit_compile=True)
tokenized_input = tokenizer(input_string, return_tensors="tf")
generated_tokens = xla_generate(**tokenized_input, num_beams=2)
decoded_text = tokenizer.decode(generated_tokens[0], skip_special_tokens=True)
print(f"Generated -- {decoded_text}")
"Generated -- TensorFlow is an open-source, open-source, distributed-source application framework for the"
```
## Tracing
When executing an XLA-enabled function for the first time, it tries to infer the computation graph in a process known as *tracing*. This is a time-consuming step, but any consecutive calls to the function will be much faster because it won't have to trace the computation graph again.
To ensure a function is only traced once, the inputs must have the same shape as when the graph was built. This usually isn't an issue for fixed input shapes like images, but it can be an issue for inputs with variable shapes like text.
One way to handle this is to pad your text so it always has the same shape. Configure padding options such as [pad_to_multiple_of](https://hf.co/docs/transformers/internal/tokenization_utils#transformers.PreTrainedTokenizerBase.pad.pad_to_multiple_of) in the tokenizer.
```py
import tensorflow as tf
from transformers import AutoTokenizer, TFAutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("openai-community/gpt2", padding_side="left", pad_token="</s>")
model = TFAutoModelForCausalLM.from_pretrained("openai-community/gpt2")
input_string = ["TensorFlow is"]
xla_generate = tf.function(model.generate, jit_compile=True)
# Call tokenizer with padding options.
tokenized_input = tokenizer(input_string, pad_to_multiple_of=8, padding=True, return_tensors="tf")
generated_tokens = xla_generate(**tokenized_input, num_beams=2)
decoded_text = tokenizer.decode(generated_tokens[0], skip_special_tokens=True)
print(f"Generated -- {decoded_text}")
```
In addition to the input shape, any changes to the generation options at any point also triggers tracing.
