في هذا الدليل، سنستعرض التقنيات الفعالة لتُحسِّن من كفاءة نشر نماذج اللغة الكبيرة:
1. سنتناول تقنية "دقة أقل" التي أثبتت الأبحاث فعاليتها في تحقيق مزايا حسابية دون التأثير بشكل ملحوظ على أداء النموذج عن طريق العمل بدقة رقمية أقل [8 بت و4 بت](/main_classes/quantization).

2. **اFlash Attention:** إن Flash Attention وهي نسخة مُعدَّلة من خوارزمية الانتباه التي لا توفر فقط نهجًا أكثر كفاءة في استخدام الذاكرة، ولكنها تحقق أيضًا كفاءة متزايدة بسبب الاستخدام الأمثل لذاكرة GPU.
3. **الابتكارات المعمارية:** حيث تم اقتراح هياكل متخصصة تسمح باستدلال أكثر فعالية نظرًا لأن نماذج اللغة الكبيرة يتم نشرها دائمًا بنفس الطريقة أثناء عملية الاستدلال، أي توليد النص التنبؤي التلقائي مع سياق الإدخال الطويل، فقد تم اقتراح بنيات نموذج متخصصة تسمح بالاستدلال الأكثر كفاءة. أهم تقدم في بنيات النماذج هنا هو [عذر](https://huggingface.co/papers/2108.12409)، [الترميز الدوار](https://huggingface.co/papers/2104.09864)، [الاهتمام متعدد الاستعلامات (MQA)](https://huggingface.co/papers/1911.02150) و [مجموعة الانتباه بالاستعلام (GQA)](https://huggingface.co/papers/2305.13245).

على مدار هذا الدليل، سنقدم تحليلًا للتوليد التنبؤي التلقائي من منظور المُوتِّرات. نتعمق في مزايا وعيوب استخدام دقة أقل، ونقدم استكشافًا شاملاً لخوارزميات الانتباه الأحدث، ونناقش بنيات نماذج نماذج اللغة الكبيرة المحسنة. سندعم الشرح بأمثلة عملية تُبرِز كل تحسين على حدة.

## Cache storage implementation
Caches are structured as a list of layers, where each layer contains a key and value cache. The key and value caches are tensors with the shape `[batch_size, num_heads, seq_len, head_dim]`.
The actual storage of key-value pairs varies between cache implementations. As an example, consider the [`DynamicCache`].
Layers can be of different types (e.g. `DynamicLayer`, `StaticLayer`, `SlidingWindowLayer`), which mostly changes how sequence length is handled and how the cache is updated.
The simplest is a `DynamicLayer` that grows as more tokens are processed. The sequence length dimension (`seq_len`) increases with each new token:
In [`DynamicCache`], the key-value pairs are stored as two lists of tensors. Each tensor in the lists have the shape `[batch_size, num_heads, seq_len, head_dim]`.
- `key_cache`: A list of tensors, one for each layer.
- `value_cache`: A list of tensors, one for each layer.
When new tokens are processed:
1. For each layer, the new key and value states are concatenated with the existing cache.
```py
cache.layers[idx].keys = torch.cat([cache.layers[idx].keys, key_states], dim=-2)
cache.layers[idx].values = torch.cat([cache.layers[idx].values, value_states], dim=-2)
self.key_cache[layer_idx] = torch.cat([self.key_cache[layer_idx], key_states], dim=-2)
self.value_cache[layer_idx] = torch.cat([self.value_cache[layer_idx], value_states], dim=-2)
```
Other layer types like `StaticLayer` and `SlidingWindowLayer` have a fixed sequence length that is set when the cache is created. This makes them compatible with `torch.compile`. In the case of `SlidingWindowLayer`, existing tokens are shifted out of the cache when a new token is added.
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.

print(tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0])
"[INST] Hello, what's your name. [/INST] Hello! My name is LLaMA,"
```
## Cache position
The cache position tracks where to insert new tokens in the attention cache. It represents the *absolute* position of each token in the context, independent of padding or batch structure. Suppose you already cached `N` tokens and are now processing `K` new tokens. The cache position for the new tokens will range from `N` to `N + K - 1`. In other words, you're processing tokens at positions - `[N, N + 1, N + 2, ..., N + K - 1]`.
Cache position is used internally for two purposes:
1. Selecting new tokens to process in the input sequence and ensuring only tokens that havent been cached yet are passed to the model's `forward`.
2. Storing key/value pairs at the correct positions in the cache. This is especially important for fixed-size caches, like [`StaticCache`], that pre-allocates a specific cache length.
The generation loop usually takes care of the cache position, but if you're writing a custom generation method, it is important that cache positions are accurate since they are used to write and read key/value states into fixed slots.

# Using Cursor as a client of transformers serve
This example shows how to use `transformers serve` as a local LLM provider for [Cursor](https://cursor.com/), the popular IDE. In this particular case, 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 a server with CORS enabled, run
```shell
transformers serve --enable-cors
```
You'll also need to expose your 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 a 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>
You're now ready to set things up on the app side! In Cursor, while you can't set a new provider, you 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 your `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"/>

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.

## Analyzer of skipped tests
### Scan skipped tests - for model adders and maintainers
This small util is a power user tool intended for model adders and maintainers. It lists all test methods
existing in `test_modeling_common.py`, inherited by all model tester classes, and scans the repository to measure
how many tests are being skipped and for which models.
### Rationale
When porting models to transformers, tests fail as they should, and sometimes `test_modeling_common` feels irreconcilable with the peculiarities of our brand new model. But how can we be sure we're not breaking everything by adding a seemingly innocent skip?
This utility:
- scans all test_modeling_common methods
- looks for times where a method is skipped
- returns a summary json you can load as a DataFrame/inspect
**For instance test_inputs_embeds is skipped in a whooping 39% proportion at the time of writing this util.**
![download-icon](https://huggingface.co/datasets/huggingface/documentation-images/resolve/f7f671f69b88ce4967e19179172c248958d35742/transformers/tests_skipped_visualisation.png)
### Usage
You can run the skipped test analyzer in two ways:
#### Full scan (default)
From the root of `transformers` repo, scans all common test methods and outputs the results to a JSON file (default: `all_tests_scan_result.json`).
```bash
python utils/scan_skipped_tests.py --output_dir path/to/output
```
- `--output_dir` (optional): Directory where the JSON results will be saved. Defaults to the current directory.
**Example output:**
```
🔬 Parsing 331 model test files once each...
📝 Aggregating 224 tests...
(224/224) test_update_candidate_strategy_with_matches_1es_3d_is_nonecodet_schedule_fa_kwargs
✅ Scan complete.
📄 JSON saved to /home/pablo/git/transformers/all_tests_scan_result.json
```
And it will generate `all_tests_scan_result.json` file that you can inspect. The JSON is indexed by method name, and each entry follows this schema, indicating the origin as well (from `common`or `GenerationMixin`.)
```json
{
"<method_name>": {
"origin": "<test suite>"
"models_ran": ["<model_name>", ...],
"models_skipped": ["<model_name>", ...],
"skipped_proportion": <float>,
"reasons_skipped": ["<model_name>: <reason>",
...
]
},
...
}
```
Which you can visualise as above with e.g. `pandas`
```python
df = pd.read_json('all_tests_scan_result.json').T
df.sort_values(by=['skipped_proportion'], ascending=False)
```
### Scan a single test method
You can focus on a specific test method using `--test_method_name`:
```bash
$ python utils/scan_skipped_tests.py --test_method_name test_inputs_embeds --output_dir path/to/output
```
- `--test_method_name`: Name of the test method to scan (e.g., `test_inputs_embeds`).
- `--output_dir` (optional): Directory where the JSON result will be saved.
**Example output:**
```bash
$ python utils/scan_skipped_tests.py --test_method_name test_inputs_embeds

# Jan: using the serving API as a local LLM provider
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.
## Running models locally
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`.
## Running models on a separate machine
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.

FlashAttention and [FlashAttention-2](./perf_infer_gpu_one#flashattention-2) break up the attention computation into smaller chunks and reduces the number of intermediate read/write operations to the GPU memory to speed up inference. FlashAttention-2 improves on the original FlashAttention algorithm by also parallelizing over sequence length dimension and better partitioning work on the hardware to reduce synchronization and communication overhead.
To use FlashAttention-2, set [attn_implementation](https://hf.co/docs/transformers/main/en/main_classes/text_generation#transformers.PreTrainedModel.from_pretrained.attn_implementation) to `"flash_attention_2"` in [`~PreTrainedModel.from_pretrained`] or set with `model.set_attention_implementation("flash_attention_2")` to dynamically update the [attention interface](./attention_interface) after the model is loaded.

Scaled dot product attention (SDPA) is automatically enabled in PyTorch 2.0 and it supports FlashAttention, xFormers, and PyTorch's C++ implementation. SDPA chooses the most performant attention algorithm if you're using a CUDA backend. For other backends, SDPA defaults to the PyTorch C++ implementation.

The BARThez model was proposed in [BARThez: a Skilled Pretrained French Sequence-to-Sequence Model](https://huggingface.co/papers/2010.12321) by Moussa Kamal Eddine, Antoine J.-P. Tixier, Michalis Vazirgiannis on 23 Oct,
2020.
The abstract of the paper:
The example below demonstrates how to predict the `<mask>` token with [`Pipeline`], [`AutoModel`], and from the command line.
*Inductive transfer learning, enabled by self-supervised learning, have taken the entire Natural Language Processing
(NLP) field by storm, with models such as BERT and BART setting new state of the art on countless natural language
understanding tasks. While there are some notable exceptions, most of the available models and research have been
conducted for the English language. In this work, we introduce BARThez, the first BART model for the French language
(to the best of our knowledge). BARThez was pretrained on a very large monolingual French corpus from past research
that we adapted to suit BART's perturbation schemes. Unlike already existing BERT-based French language models such as
CamemBERT and FlauBERT, BARThez is particularly well-suited for generative tasks, since not only its encoder but also
its decoder is pretrained. In addition to discriminative tasks from the FLUE benchmark, we evaluate BARThez on a novel
summarization dataset, OrangeSum, that we release with this paper. We also continue the pretraining of an already
pretrained multilingual BART on BARThez's corpus, and we show that the resulting model, which we call mBARTHez,
provides a significant boost over vanilla BARThez, and is on par with or outperforms CamemBERT and FlauBERT.*

# CamemBERT
[CamemBERT](https://huggingface.co/papers/1911.03894) is a language model based on [RoBERTa](./roberta), but trained specifically on French text from the OSCAR dataset, making it more effective for French language tasks.

What sets CamemBERT apart is that it learned from a huge, high quality collection of French data, as opposed to mixing lots of languages. This helps it really understand French better than many multilingual models.
## Overview
Common applications of CamemBERT include masked language modeling (Fill-mask prediction), text classification (sentiment analysis), token classification (entity recognition) and sentence pair classification (entailment tasks).
The CamemBERT model was proposed in [CamemBERT: a Tasty French Language Model](https://huggingface.co/papers/1911.03894) by
[Louis Martin](https://huggingface.co/louismartin), [Benjamin Muller](https://huggingface.co/benjamin-mlr), [Pedro Javier Ortiz Suárez](https://huggingface.co/pjox), Yoann Dupont, Laurent Romary, Éric Villemonte de la
Clergerie, [Djamé Seddah](https://huggingface.co/Djame), and [Benoît Sagot](https://huggingface.co/sagot). It is based on Facebook's RoBERTa model released in 2019. It is a model
trained on 138GB of French text.
You can find all the original CamemBERT checkpoints under the [ALMAnaCH](https://huggingface.co/almanach/models?search=camembert) organization.

*Pretrained language models are now ubiquitous in Natural Language Processing. Despite their success, most available
models have either been trained on English data or on the concatenation of data in multiple languages. This makes
practical use of such models --in all languages except English-- very limited. Aiming to address this issue for French,
we release CamemBERT, a French version of the Bi-directional Encoders for Transformers (BERT). We measure the
performance of CamemBERT compared to multilingual models in multiple downstream tasks, namely part-of-speech tagging,
dependency parsing, named-entity recognition, and natural language inference. CamemBERT improves the state of the art
for most of the tasks considered. We release the pretrained model for CamemBERT hoping to foster research and
downstream applications for French NLP.*
The examples below demonstrate how to predict the `<mask>` token with [`Pipeline`], [`AutoModel`], and from the command line.

The CLAP model was proposed in [Large Scale Contrastive Language-Audio pretraining with
feature fusion and keyword-to-caption augmentation](https://huggingface.co/papers/2211.06687) by Yusong Wu, Ke Chen, Tianyu Zhang, Yuchen Hui, Taylor Berg-Kirkpatrick, Shlomo Dubnov.

CLAP (Contrastive Language-Audio Pretraining) is a neural network trained on a variety of (audio, text) pairs. It can be instructed in to predict the most relevant text snippet, given an audio, without directly optimizing for the task. The CLAP model uses a SWINTransformer to get audio features from a log-Mel spectrogram input, and a RoBERTa model to get text features. Both the text and audio features are then projected to a latent space with identical dimension. The dot product between the projected audio and text features is then used as a similar score.
The example below demonstrates how to extract text embeddings with the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="AutoModel">
*Contrastive learning has shown remarkable success in the field of multimodal representation learning. In this paper, we propose a pipeline of contrastive language-audio pretraining to develop an audio representation by combining audio data with natural language descriptions. To accomplish this target, we first release LAION-Audio-630K, a large collection of 633,526 audio-text pairs from different data sources. Second, we construct a contrastive language-audio pretraining model by considering different audio encoders and text encoders. We incorporate the feature fusion mechanism and keyword-to-caption augmentation into the model design to further enable the model to process audio inputs of variable lengths and enhance the performance. Third, we perform comprehensive experiments to evaluate our model across three tasks: text-to-audio retrieval, zero-shot audio classification, and supervised audio classification. The results demonstrate that our model achieves superior performance in text-to-audio retrieval task. In audio classification tasks, the model achieves state-of-the-art performance in the zeroshot setting and is able to obtain performance comparable to models' results in the non-zero-shot setting.

The Conversational Speech Model (CSM) is the first open-source contextual text-to-speech model [released by Sesame](https://www.sesame.com/research/crossing_the_uncanny_valley_of_voice). It is designed to generate natural-sounding speech with or without conversational context. This context typically consists of multi-turn dialogue between speakers, represented as sequences of text and corresponding spoken audio.
**Model Architecture:**
CSM is composed of two LLaMA-style auto-regressive transformer decoders: a backbone decoder that predicts the first codebook token and a depth decoder that generates the remaining tokens. It uses the pretrained codec model [Mimi](./mimi), introduced by Kyutai, to encode speech into discrete codebook tokens and decode them back into audio.

# 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.

# DETR
[DETR](https://huggingface.co/papers/2005.12872) consists of a convolutional backbone followed by an encoder-decoder Transformer which can be trained end-to-end for object detection. It greatly simplifies a lot of the complexity of models like Faster-R-CNN and Mask-R-CNN, which use things like region proposals, non-maximum suppression procedure and anchor generation. Moreover, DETR can also be naturally extended to perform panoptic segmentation, by simply adding a mask head on top of the decoder outputs.

The DETR model was proposed in [End-to-End Object Detection with Transformers](https://huggingface.co/papers/2005.12872) by
Nicolas Carion, Francisco Massa, Gabriel Synnaeve, Nicolas Usunier, Alexander Kirillov and Sergey Zagoruyko. DETR
consists of a convolutional backbone followed by an encoder-decoder Transformer which can be trained end-to-end for
object detection. It greatly simplifies a lot of the complexity of models like Faster-R-CNN and Mask-R-CNN, which use
things like region proposals, non-maximum suppression procedure and anchor generation. Moreover, DETR can also be
naturally extended to perform panoptic segmentation, by simply adding a mask head on top of the decoder outputs.
The example below demonstrates how to perform object detection with the [`Pipeline`] or the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*We present a new method that views object detection as a direct set prediction problem. Our approach streamlines the
detection pipeline, effectively removing the need for many hand-designed components like a non-maximum suppression
procedure or anchor generation that explicitly encode our prior knowledge about the task. The main ingredients of the
new framework, called DEtection TRansformer or DETR, are a set-based global loss that forces unique predictions via
bipartite matching, and a transformer encoder-decoder architecture. Given a fixed small set of learned object queries,
DETR reasons about the relations of the objects and the global image context to directly output the final set of
predictions in parallel. The new model is conceptually simple and does not require a specialized library, unlike many
other modern detectors. DETR demonstrates accuracy and run-time performance on par with the well-established and
highly-optimized Faster RCNN baseline on the challenging COCO object detection dataset. Moreover, DETR can be easily
generalized to produce panoptic segmentation in a unified manner. We show that it significantly outperforms competitive

<summary>How DETR works</summary>
## How DETR works
Here's a TLDR explaining how [`~transformers.DetrForObjectDetection`] works:
First, an image is sent through a pre-trained convolutional backbone (in the paper, the authors use ResNet-50/ResNet-101). Let's assume we also add a batch dimension. This means that the input to the backbone is a tensor of shape `(batch_size, 3, height, width)`, assuming the image has 3 color channels (RGB). The CNN backbone outputs a new lower-resolution feature map, typically of shape `(batch_size, 2048, height/32, width/32)`. This is then projected to match the hidden dimension of the Transformer of DETR, which is `256` by default, using a `nn.Conv2D` layer. So now, we have a tensor of shape `(batch_size, 256, height/32, width/32).` Next, the feature map is flattened and transposed to obtain a tensor of shape `(batch_size, seq_len, d_model)` = `(batch_size, width/32*height/32, 256)`. So a difference with NLP models is that the sequence length is actually longer than usual, but with a smaller `d_model` (which in NLP is typically 768 or higher).

Next, this is sent through the encoder, outputting `encoder_hidden_states` of the same shape (you can consider these as image features). Next, so-called **object queries** are sent through the decoder. This is a tensor of shape `(batch_size, num_queries, d_model)`, with `num_queries` typically set to 100 and initialized with zeros. These input embeddings are learnt positional encodings that the authors refer to as object queries, and similarly to the encoder, they are added to the input of each attention layer. Each object query will look for a particular object in the image. The decoder updates these embeddings through multiple self-attention and encoder-decoder attention layers to output `decoder_hidden_states` of the same shape: `(batch_size, num_queries, d_model)`. Next, two heads are added on top for object detection: a linear layer for classifying each object query into one of the objects or "no object", and a MLP to predict bounding boxes for each query.

are added on top for object detection: a linear layer for classifying each object query into one of the objects or "no
object", and a MLP to predict bounding boxes for each query.
The model is trained using a **bipartite matching loss**: so what we actually do is compare the predicted classes + bounding boxes of each of the N = 100 object queries to the ground truth annotations, padded up to the same length N (so if an image only contains 4 objects, 96 annotations will just have a "no object" as class and "no bounding box" as bounding box). The [Hungarian matching algorithm](https://en.wikipedia.org/wiki/Hungarian_algorithm) is used to find an optimal one-to-one mapping of each of the N queries to each of the N annotations. Next, standard cross-entropy (for the classes) and a linear combination of the L1 and [generalized IoU loss](https://giou.stanford.edu/) (for the bounding boxes) are used to optimize the parameters of the model.

DETR can be naturally extended to perform panoptic segmentation (which unifies semantic segmentation and instance segmentation). [`~transformers.DetrForSegmentation`] adds a segmentation mask head on top of [`~transformers.DetrForObjectDetection`]. The mask head can be trained either jointly, or in a two steps process, where one first trains a [`~transformers.DetrForObjectDetection`] model to detect bounding boxes around both "things" (instances) and "stuff" (background things like trees, roads, sky), then freeze all the weights and train only the mask head for 25 epochs. Experimentally, these two approaches give similar results. Note that predicting boxes is required for the training to be possible, since the Hungarian matching is computed using distances between boxes.

## Usage tips
## Notes
- DETR uses so-called **object queries** to detect objects in an image. The number of queries determines the maximum
number of objects that can be detected in a single image, and is set to 100 by default (see parameter
`num_queries` of [`~transformers.DetrConfig`]). Note that it's good to have some slack (in COCO, the
authors used 100, while the maximum number of objects in a COCO image is ~70).
- The decoder of DETR updates the query embeddings in parallel. This is different from language models like GPT-2,
which use autoregressive decoding instead of parallel. Hence, no causal attention mask is used.
- DETR adds position embeddings to the hidden states at each self-attention and cross-attention layer before projecting
to queries and keys. For the position embeddings of the image, one can choose between fixed sinusoidal or learned
absolute position embeddings. By default, the parameter `position_embedding_type` of
[`~transformers.DetrConfig`] is set to `"sine"`.
- During training, the authors of DETR did find it helpful to use auxiliary losses in the decoder, especially to help
the model output the correct number of objects of each class. If you set the parameter `auxiliary_loss` of
[`~transformers.DetrConfig`] to `True`, then prediction feedforward neural networks and Hungarian losses
are added after each decoder layer (with the FFNs sharing parameters).
- If you want to train the model in a distributed environment across multiple nodes, then one should update the
_num_boxes_ variable in the _DetrLoss_ class of _modeling_detr.py_. When training on multiple nodes, this should be
set to the average number of target boxes across all nodes, as can be seen in the original implementation [here](https://github.com/facebookresearch/detr/blob/a54b77800eb8e64e3ad0d8237789fcbf2f8350c5/models/detr.py#L227-L232).
- [`~transformers.DetrForObjectDetection`] and [`~transformers.DetrForSegmentation`] can be initialized with
any convolutional backbone available in the [timm library](https://github.com/rwightman/pytorch-image-models).
Initializing with a MobileNet backbone for example can be done by setting the `backbone` attribute of
[`~transformers.DetrConfig`] to `"tf_mobilenetv3_small_075"`, and then initializing the model with that
config.
- DETR resizes the input images such that the shortest side is at least a certain amount of pixels while the longest is
at most 1333 pixels. At training time, scale augmentation is used such that the shortest side is randomly set to at
least 480 and at most 800 pixels. At inference time, the shortest side is set to 800. One can use
[`~transformers.DetrImageProcessor`] to prepare images (and optional annotations in COCO format) for the
model. Due to this resizing, images in a batch can have different sizes. DETR solves this by padding images up to the
largest size in a batch, and by creating a pixel mask that indicates which pixels are real/which are padding.
Alternatively, one can also define a custom `collate_fn` in order to batch images together, using
[`~transformers.DetrImageProcessor.pad_and_create_pixel_mask`].
- The size of the images will determine the amount of memory being used, and will thus determine the `batch_size`.
It is advised to use a batch size of 2 per GPU. See [this Github thread](https://github.com/facebookresearch/detr/issues/150) for more info.

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) is used - DAC encodes speech into discrete codebook
for the audio portion (decoder), a pretrained codec model [DAC](./dac.md) is used - DAC encodes speech into discrete codebook
tokens and decodes them back into audio.

# EfficientLoFTR
[EfficientLoFTR](https://huggingface.co/papers/2403.04765) is an efficient detector-free local feature matching method that produces semi-dense matches across images with sparse-like speed. It builds upon the original [LoFTR](https://huggingface.co/papers/2104.00680) architecture but introduces significant improvements for both efficiency and accuracy. The key innovation is an aggregated attention mechanism with adaptive token selection that makes the model ~2.5× faster than LoFTR while achieving higher accuracy. EfficientLoFTR can even surpass state-of-the-art efficient sparse matching pipelines like [SuperPoint](./superpoint) + [LightGlue](./lightglue) in terms of speed, making it suitable for large-scale or latency-sensitive applications such as image retrieval and 3D reconstruction.

## Notes
- EfficientLoFTR is designed for efficiency while maintaining high accuracy. It uses an aggregated attention mechanism with adaptive token selection to reduce computational overhead compared to the original LoFTR.
```py
from transformers import AutoImageProcessor, AutoModelForKeypointMatching
import torch
from PIL import Image
import requests
processor = AutoImageProcessor.from_pretrained("zju-community/efficientloftr")
model = AutoModelForKeypointMatching.from_pretrained("zju-community/efficientloftr")
# EfficientLoFTR requires pairs of images
images = [image1, image2]
inputs = processor(images, return_tensors="pt")
outputs = model(**inputs)
# Extract matching information
keypoints = outputs.keypoints # Keypoints in both images
matches = outputs.matches # Matching indices
matching_scores = outputs.matching_scores # Confidence scores
```
- The model produces semi-dense matches, offering a good balance between the density of matches and computational efficiency. It excels in handling large viewpoint changes and texture-poor scenarios.
- For better visualization and analysis, use the [`~EfficientLoFTRImageProcessor.post_process_keypoint_matching`] method to get matches in a more readable format.
```py
# Process outputs for visualization
image_sizes = [[(image.height, image.width) for image in images]]
processed_outputs = processor.post_process_keypoint_matching(outputs, image_sizes, threshold=0.2)
for i, output in enumerate(processed_outputs):
print(f"For the image pair {i}")
for keypoint0, keypoint1, matching_score in zip(
output["keypoints0"], output["keypoints1"], output["matching_scores"]
):
print(f"Keypoint at {keypoint0.numpy()} matches with keypoint at {keypoint1.numpy()} with score {matching_score}")
```
- Visualize the matches between the images using the built-in plotting functionality.
```py
# Easy visualization using the built-in plotting method
visualized_images = processor.visualize_keypoint_matching(images, processed_outputs)
```
- EfficientLoFTR uses a novel two-stage correlation layer that achieves accurate subpixel correspondences, improving upon the original LoFTR's fine correlation module.

# Encoder Decoder Models
[`EncoderDecoderModel`](https://huggingface.co/papers/1706.03762) initializes a sequence-to-sequence model with any pretrained autoencoder and pretrained autoregressive model. It is effective for sequence generation tasks as demonstrated in [Text Summarization with Pretrained Encoders](https://huggingface.co/papers/1908.08345) which uses [`BertModel`] as the encoder and decoder.

## Overview
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line.
The [`EncoderDecoderModel`] can be used to initialize a sequence-to-sequence model with any
pretrained autoencoding model as the encoder and any pretrained autoregressive model as the decoder.
<hfoptions id="usage">
<hfoption id="Pipeline">
The effectiveness of initializing sequence-to-sequence models with pretrained checkpoints for sequence generation tasks
was shown in [Leveraging Pre-trained Checkpoints for Sequence Generation Tasks](https://huggingface.co/papers/1907.12461) by
Sascha Rothe, Shashi Narayan, Aliaksei Severyn.
After such an [`EncoderDecoderModel`] has been trained/fine-tuned, it can be saved/loaded just like
any other models (see the examples for more information).
An application of this architecture could be to leverage two pretrained [`BertModel`] as the encoder
and decoder for a summarization model as was shown in: [Text Summarization with Pretrained Encoders](https://huggingface.co/papers/1908.08345) by Yang Liu and Mirella Lapata.
## Randomly initializing `EncoderDecoderModel` from model configurations.
[`EncoderDecoderModel`] can be randomly initialized from an encoder and a decoder config. In the following example, we show how to do this using the default [`BertModel`] configuration for the encoder and the default [`BertForCausalLM`] configuration for the decoder.
```python
from transformers import pipeline
>>> from transformers import BertConfig, EncoderDecoderConfig, EncoderDecoderModel
summarizer = pipeline(
"summarization",
model="patrickvonplaten/bert2bert-cnn_dailymail-fp16",
device=0
)
>>> config_encoder = BertConfig()
>>> config_decoder = BertConfig()
text = "Plants create energy through a process known as photosynthesis. This involves capturing sunlight and converting carbon dioxide and water into glucose and oxygen."
print(summarizer(text))
>>> config = EncoderDecoderConfig.from_encoder_decoder_configs(config_encoder, config_decoder)
>>> model = EncoderDecoderModel(config=config)
```
</hfoption>
<hfoption id="AutoModel">
## Initialising `EncoderDecoderModel` from a pretrained encoder and a pretrained decoder.
[`EncoderDecoderModel`] can be initialized from a pretrained encoder checkpoint and a pretrained decoder checkpoint. Note that any pretrained auto-encoding model, *e.g.* BERT, can serve as the encoder and both pretrained auto-encoding models, *e.g.* BERT, pretrained causal language models, *e.g.* GPT2, as well as the pretrained decoder part of sequence-to-sequence models, *e.g.* decoder of BART, can be used as the decoder.
Depending on which architecture you choose as the decoder, the cross-attention layers might be randomly initialized.
Initializing [`EncoderDecoderModel`] from a pretrained encoder and decoder checkpoint requires the model to be fine-tuned on a downstream task, as has been shown in [the *Warm-starting-encoder-decoder blog post*](https://huggingface.co/blog/warm-starting-encoder-decoder).
To do so, the `EncoderDecoderModel` class provides a [`EncoderDecoderModel.from_encoder_decoder_pretrained`] method.
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
>>> from transformers import EncoderDecoderModel, BertTokenizer
tokenizer = AutoTokenizer.from_pretrained("patrickvonplaten/bert2bert-cnn_dailymail-fp16")
model = AutoModelForCausalLM.from_pretrained("patrickvonplaten/bert2bert-cnn_dailymail-fp16", torch_dtype=torch.bfloat16, device_map="auto",attn_implementation="sdpa")
text = "Plants create energy through a process known as photosynthesis. This involves capturing sunlight and converting carbon dioxide and water into glucose and oxygen."
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True).to(model.device)
summary = model.generate(**inputs, max_length=60, num_beams=4, early_stopping=True)
print(tokenizer.decode(summary[0], skip_special_tokens=True))
>>> tokenizer = BertTokenizer.from_pretrained("google-bert/bert-base-uncased")
>>> model = EncoderDecoderModel.from_encoder_decoder_pretrained("google-bert/bert-base-uncased", "google-bert/bert-base-uncased")
```
</hfoption>
<hfoption id="transformers CLI">
## Loading an existing `EncoderDecoderModel` checkpoint and perform inference.
```bash
echo -e "Plants create energy through a process known as photosynthesis. This involves capturing sunlight and converting carbon dioxide and water into glucose and oxygen." | transformers-cli run --task summarization --model "patrickvonplaten/bert2bert-cnn_dailymail-fp16" --device 0
```
To load fine-tuned checkpoints of the `EncoderDecoderModel` class, [`EncoderDecoderModel`] provides the `from_pretrained(...)` method just like any other model architecture in Transformers.
</hfoption>
</hfoptions>
## Notes
- [`EncoderDecoderModel`] can be initialized using any pretrained encoder and decoder. But depending on the decoder architecture, the cross-attention layers may be randomly initialized.
These models require downstream fine-tuning, as discussed in this [blog post](https://huggingface.co/blog/warm-starting-encoder-decoder). Use [`~EncoderDecoderModel.from_encoder_decoder_pretrained`] to combine encoder and decoder checkpoints.
To perform inference, one uses the [`generate`] method, which allows to autoregressively generate text. This method supports various forms of decoding, such as greedy, beam search and multinomial sampling.
```python
from transformers import EncoderDecoderModel, BertTokenizer
>>> from transformers import AutoTokenizer, EncoderDecoderModel
tokenizer = BertTokenizer.from_pretrained("google-bert/bert-base-uncased")
model = EncoderDecoderModel.from_encoder_decoder_pretrained(
"google-bert/bert-base-uncased",
"google-bert/bert-base-uncased"
)
>>> # load a fine-tuned seq2seq model and corresponding tokenizer
>>> model = EncoderDecoderModel.from_pretrained("patrickvonplaten/bert2bert_cnn_daily_mail")
>>> tokenizer = AutoTokenizer.from_pretrained("patrickvonplaten/bert2bert_cnn_daily_mail")
>>> # let's perform inference on a long piece of text
>>> ARTICLE_TO_SUMMARIZE = (
... "PG&E stated it scheduled the blackouts in response to forecasts for high winds "
... "amid dry conditions. The aim is to reduce the risk of wildfires. Nearly 800 thousand customers were "
... "scheduled to be affected by the shutoffs which were expected to last through at least midday tomorrow."
... )
>>> input_ids = tokenizer(ARTICLE_TO_SUMMARIZE, return_tensors="pt").input_ids
>>> # autoregressively generate summary (uses greedy decoding by default)
>>> generated_ids = model.generate(input_ids)
>>> generated_text = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
>>> print(generated_text)
nearly 800 thousand customers were affected by the shutoffs. the aim is to reduce the risk of wildfires. nearly 800, 000 customers were expected to be affected by high winds amid dry conditions. pg & e said it scheduled the blackouts to last through at least midday tomorrow.
```
- Encoder Decoder models can be fine-tuned like BART, T5 or any other encoder-decoder model. Only 2 inputs are required to compute a loss, `input_ids` and `labels`. Refer to this [notebook](https://colab.research.google.com/drive/1WIk2bxglElfZewOHboPFNj8H44_VAyKE?usp=sharing#scrollTo=ZwQIEhKOrJpl) for a more detailed training example.
## Loading a PyTorch checkpoint into `TFEncoderDecoderModel`.
[`TFEncoderDecoderModel.from_pretrained`] currently doesn't support initializing the model from a
pytorch checkpoint. Passing `from_pt=True` to this method will throw an exception. If there are only pytorch
checkpoints for a particular encoder-decoder model, a workaround is:
```python
>>> # a workaround to load from pytorch checkpoint
>>> from transformers import EncoderDecoderModel, TFEncoderDecoderModel
>>> _model = EncoderDecoderModel.from_pretrained("patrickvonplaten/bert2bert-cnn_dailymail-fp16")
>>> _model.encoder.save_pretrained("./encoder")
>>> _model.decoder.save_pretrained("./decoder")
>>> model = TFEncoderDecoderModel.from_encoder_decoder_pretrained(
... "./encoder", "./decoder", encoder_from_pt=True, decoder_from_pt=True
... )
>>> # This is only for copying some specific attributes of this particular model.
>>> model.config = _model.config
```
## Training
Once the model is created, it can be fine-tuned similar to BART, T5 or any other encoder-decoder model.
As you can see, only 2 inputs are required for the model in order to compute a loss: `input_ids` (which are the
`input_ids` of the encoded input sequence) and `labels` (which are the `input_ids` of the encoded
target sequence).
```python
>>> from transformers import BertTokenizer, EncoderDecoderModel
@ -120,42 +147,11 @@ model = EncoderDecoderModel.from_encoder_decoder_pretrained(
>>> loss = model(input_ids=input_ids, labels=labels).loss
```
- [`EncoderDecoderModel`] can be randomly initialized from an encoder and a decoder config as shown below.
Detailed [colab](https://colab.research.google.com/drive/1WIk2bxglElfZewOHboPFNj8H44_VAyKE?usp=sharing#scrollTo=ZwQIEhKOrJpl) for training.

>>> config_encoder = BertConfig()
>>> config_decoder = BertConfig()
>>> config = EncoderDecoderConfig.from_encoder_decoder_configs(config_encoder, config_decoder)
>>> model = EncoderDecoderModel(config=config)
```
- The Encoder Decoder Model can also be used for translation as shown below.
```python
from transformers import AutoTokenizer, EncoderDecoderModel
# Load a pre-trained translation model
model_name = "google/bert2bert_L-24_wmt_en_de"
tokenizer = AutoTokenizer.from_pretrained(model_name, pad_token="<pad>", eos_token="</s>", bos_token="<s>")
model = EncoderDecoderModel.from_pretrained(model_name)
# Input sentence to translate
input_text = "Plants create energy through a process known as"
# Encode the input text
inputs = tokenizer(input_text, return_tensors="pt", add_special_tokens=False).input_ids
# Generate the translated output
outputs = model.generate(inputs)[0]
# Decode the output tokens to get the translated sentence
translated_text = tokenizer.decode(outputs, skip_special_tokens=True)
print("Translated text:", translated_text)
```

# Evolla
## Overview
The Evolla model was proposed in [Decoding the Molecular Language of Proteins with Evolla](https://doi.org/10.1101/2025.01.05.630192) by [Zhou et al.](https://doi.org/10.1101/2025.01.05.630192).
Evolla is an advanced 80-billion-parameter protein-language generative model designed to decode the molecular language of proteins. It integrates information from protein sequences, structures, and user queries to generate precise and contextually nuanced insights into protein function. Trained on an unprecedented AI-generated dataset of 546 million protein question-answer pairs and 150 billion word tokens, Evolla significantly advances research in proteomics and functional genomics, providing expert-level insights and shedding light on the molecular logic encoded in proteins.
The abstract from the paper is the following:
*Proteins, natures intricate molecular machines, are the products of billions of years of evolution and play fundamental roles in sustaining life. Yet, deciphering their molecular language - that is, understanding how protein sequences and structures encode and determine biological functions - remains a corner-stone challenge in modern biology. Here, we introduce Evolla, an 80 billion frontier protein-language generative model designed to decode the molecular language of proteins. By integrating information from protein sequences, structures, and user queries, Evolla generates precise and contextually nuanced insights into protein function. A key innovation of Evolla lies in its training on an unprecedented AI-generated dataset: 546 million protein question-answer pairs and 150 billion word tokens, designed to reflect the immense complexity and functional diversity of proteins. Post-pretraining, Evolla integrates Direct Preference Optimization (DPO) to refine the model based on preference signals and Retrieval-Augmented Generation (RAG) for external knowledge incorporation, improving response quality and relevance. To evaluate its performance, we propose a novel framework, Instructional Response Space (IRS), demonstrating that Evolla delivers expert-level insights, advancing research in proteomics and functional genomics while shedding light on the molecular logic encoded in proteins. The online demo is available at http://www.chat-protein.com/.*
Examples:
```python
processor = EvollaProcessor.from_pretrained("westlake-repl/Evolla-10B-DPO-hf")
model = EvollaForProteinText2Text.from_pretrained("westlake-repl/Evolla-10B-DPO-hf")
# aa_seq should have same length as foldseek
protein_inputs = [
{
"aa_seq": "MATGGRRG...",
"foldseek": "###lqpfd...", # hashtag means the low-confidence foldseek tokens
},
{
"aa_seq": "MLPGLALL...",
"foldseek": "dfwwkwad...",
}
]
message_list = [
[
{
"role": "system",
"content": "You are an AI expert that can answer any questions about protein.",
},
{"role": "user", "content": "What is the function of this protein?"},
],
[
{
"role": "system",
"content": "You are an AI expert that can answer any questions about protein.",
},
{"role": "user", "content": "What is the function of this protein?"},
]
]
input_dict = processor(
protein_informations, messages_list, return_tensors="pt", text_max_length=512, protein_max_length=1024
)
with torch.no_grad():
generated_ids = hf_model.generate(**input_dict)
generated_texts = processor.batch_decode(
generated_ids, skip_special_tokens=True
)

# EXAONE 4
## Overview
**[EXAONE 4.0](https://github.com/LG-AI-EXAONE/EXAONE-4.0)** model is the language model, which integrates a **Non-reasoning mode** and **Reasoning mode** to achieve both the excellent usability of [EXAONE 3.5](https://github.com/LG-AI-EXAONE/EXAONE-3.5) and the advanced reasoning abilities of [EXAONE Deep](https://github.com/LG-AI-EXAONE/EXAONE-Deep). To pave the way for the agentic AI era, EXAONE 4.0 incorporates essential features such as agentic tool use, and its multilingual capabilities are extended
to support Spanish in addition to English and Korean.
The EXAONE 4.0 model series consists of two sizes: a mid-size **32B** model optimized for high performance, and a small-size **1.2B** model designed for on-device applications.
In the EXAONE 4.0 architecture, we apply new architectural changes compared to previous EXAONE models as below:
1. **Hybrid Attention**: For the 32B model, we adopt hybrid attention scheme, which combines *Local attention (sliding window attention)* with *Global attention (full attention)* in a 3:1 ratio. We do not use RoPE (Rotary Positional Embedding) for global attention for better global context understanding.
2. **QK-Reorder-Norm**: We reorder the LayerNorm position from the traditional Pre-LN scheme by applying LayerNorm directly to the attention and MLP outputs, and we add RMS normalization right after the Q and K projection. It helps yield better performance on downstream tasks despite consuming more computation.
For more details, please refer to our [technical report](https://arxiv.org/abs/2507.11407), [HuggingFace paper](https://huggingface.co/papers/2507.11407), [blog](https://www.lgresearch.ai/blog/view?seq=576), and [GitHub](https://github.com/LG-AI-EXAONE/EXAONE-4.0).
All model weights including quantized versions are available at [Huggingface Collections](https://huggingface.co/collections/LGAI-EXAONE/exaone-40-686b2e0069800c835ed48375).

## Usage tips
### Non-reasoning mode
For general use, you can use the EXAONE 4.0 models with the following example:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "LGAI-EXAONE/EXAONE-4.0-32B"
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype="bfloat16",
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)
# choose your prompt
prompt = "Explain how wonderful you are"
prompt = "Explica lo increíble que eres"
prompt = "너가 얼마나 대단한지 설명해 봐"
messages = [
{"role": "user", "content": prompt}
]
input_ids = tokenizer.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt"
)
output = model.generate(
input_ids.to(model.device),
max_new_tokens=128,
do_sample=False,
)
print(tokenizer.decode(output[0]))
```
### Reasoning mode
The EXAONE 4.0 models have reasoning capabilities for handling complex problems. You can activate reasoning mode by using the `enable_thinking=True` argument with the tokenizer, which opens a reasoning block that starts with `<think>` tag without closing it.
```python
messages = [
{"role": "user", "content": "Which one is bigger, 3.12 vs 3.9?"}
]
input_ids = tokenizer.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt",
enable_thinking=True,
)
output = model.generate(
input_ids.to(model.device),
max_new_tokens=128,
do_sample=True,
temperature=0.6,
top_p=0.95
)
print(tokenizer.decode(output[0]))
```
> [!IMPORTANT]
> The model generation with reasoning mode can be affected sensitively by sampling parameters, so please refer to the [Usage Guideline](https://github.com/LG-AI-EXAONE/EXAONE-4.0#usage-guideline) on official GitHub page for better quality.
### Agentic tool use
The EXAONE 4.0 models can be used as agents with their tool calling capabilities. You can provide tool schemas to the model for effective tool calling.
```python
import random
def roll_dice(max_num: int):
return random.randint(1, max_num)
tools = [
{
"type": "function",
"function": {
"name": "roll_dice",
"description": "Roll a dice with the number 1 to N. User can select the number N.",
"parameters": {
"type": "object",
"required": ["max_num"],
"properties": {
"max_num": {
"type": "int",
"description": "Max number of the dice"
}
}
}
}
}
]
messages = [
{"role": "user", "content": "Roll D6 dice twice!"}
]
input_ids = tokenizer.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_tensors="pt",
tools=tools,
)
output = model.generate(
input_ids.to(model.device),
max_new_tokens=1024,
do_sample=True,
temperature=0.6,
top_p=0.95,
)
print(tokenizer.decode(output[0]))

## Notes
- `GraniteMoeHybridForCausalLM` supports padding-free training which concatenates distinct training examples while still processing inputs as separate batches. It can significantly accelerate inference by [~2x](https://github.com/huggingface/transformers/pull/35861#issue-2807873129) (depending on model and data distribution) and reduce memory-usage if there are examples of varying lengths by avoiding unnecessary compute and memory overhead from padding tokens.
Padding-free training requires the `flash-attn`, `mamba-ssm`, and `causal-conv1d` packages and the following arguments must be passed to the model in addition to `input_ids` and `labels`.
- `position_ids: torch.LongTensor`: the position index of each token in each sequence.
- `seq_idx: torch.IntTensor`: the index of each sequence in the batch.
- Each of the [`FlashAttentionKwargs`]
- `cu_seq_lens_q: torch.LongTensor`: the cumulative sequence lengths of all queries.
- `cu_seq_lens_k: torch.LongTensor`: the cumulative sequence lengths of all keys.
- `max_length_q: int`: the longest query length in the batch.
- `max_length_k: int`: the longest key length in the batch.
The `attention_mask` inputs should not be provided. The [`DataCollatorWithFlattening`] programmatically generates the set of additional arguments above using `return_seq_idx=True` and `return_flash_attn_kwargs=True`. See the [Improving Hugging Face Training Efficiency Through Packing with Flash Attention](https://huggingface.co/blog/packing-with-FA2) blog post for additional information.

# I-JEPA
[I-JEPA](https://huggingface.co/papers/2301.08243) is a self-supervised learning method that learns semantic image representations by predicting parts of an image from other parts of the image. It compares the abstract representations of the image (rather than pixel level comparisons), which avoids the typical pitfalls of data augmentation bias and pixel-level details that don't capture semantic meaning.

## Overview
The I-JEPA model was proposed in [Image-based Joint-Embedding Predictive Architecture](https://huggingface.co/papers/2301.08243) by Mahmoud Assran, Quentin Duval, Ishan Misra, Piotr Bojanowski, Pascal Vincent, Michael Rabbat, Yann LeCun, Nicolas Ballas.
I-JEPA is a self-supervised learning method that predicts the representations of one part of an image based on other parts of the same image. This approach focuses on learning semantic features without relying on pre-defined invariances from hand-crafted data transformations, which can bias specific tasks, or on filling in pixel-level details, which often leads to less meaningful representations.

The abstract from the paper is the following:
This paper demonstrates an approach for learning highly semantic image representations without relying on hand-crafted data-augmentations. We introduce the Image- based Joint-Embedding Predictive Architecture (I-JEPA), a non-generative approach for self-supervised learning from images. The idea behind I-JEPA is simple: from a single context block, predict the representations of various target blocks in the same image. A core design choice to guide I-JEPA towards producing semantic representations is the masking strategy; specifically, it is crucial to (a) sample tar- get blocks with sufficiently large scale (semantic), and to (b) use a sufficiently informative (spatially distributed) context block. Empirically, when combined with Vision Transform- ers, we find I-JEPA to be highly scalable. For instance, we train a ViT-Huge/14 on ImageNet using 16 A100 GPUs in under 72 hours to achieve strong downstream performance across a wide range of tasks, from linear classification to object counting and depth prediction.

# 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))

# LightGlue
[LightGlue](https://arxiv.org/abs/2306.13643) is a deep neural network that learns to match local features across images. It revisits multiple design decisions of SuperGlue and derives simple but effective improvements. Cumulatively, these improvements make LightGlue more efficient - in terms of both memory and computation, more accurate, and much easier to train. Similar to [SuperGlue](https://huggingface.co/magic-leap-community/superglue_outdoor), this model consists of matching two sets of local features extracted from two images, with the goal of being faster than SuperGlue. Paired with the [SuperPoint model](https://huggingface.co/magic-leap-community/superpoint), it can be used to match two images and estimate the pose between them.
## Overview
You can find all the original LightGlue checkpoints under the [ETH-CVG](https://huggingface.co/ETH-CVG) organization.
The LightGlue model was proposed in [LightGlue: Local Feature Matching at Light Speed](https://arxiv.org/abs/2306.13643)
by Philipp Lindenberger, Paul-Edouard Sarlin and Marc Pollefeys.

Similar to [SuperGlue](https://huggingface.co/magic-leap-community/superglue_outdoor), this model consists of matching
two sets of local features extracted from two images, its goal is to be faster than SuperGlue. Paired with the
[SuperPoint model](https://huggingface.co/magic-leap-community/superpoint), it can be used to match two images and
estimate the pose between them. This model is useful for tasks such as image matching, homography estimation, etc.
The example below demonstrates how to match keypoints between two images with the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="AutoModel">
*We introduce LightGlue, a deep neural network that learns to match local features across images. We revisit multiple
design decisions of SuperGlue, the state of the art in sparse matching, and derive simple but effective improvements.
Cumulatively, they make LightGlue more efficient - in terms of both memory and computation, more accurate, and much
easier to train. One key property is that LightGlue is adaptive to the difficulty of the problem: the inference is much
faster on image pairs that are intuitively easy to match, for example because of a larger visual overlap or limited
appearance change. This opens up exciting prospects for deploying deep matchers in latency-sensitive applications like
3D reconstruction. The code and trained models are publicly available at this [https URL](https://github.com/cvg/LightGlue)*
```py
## How to use
Here is a quick example of using the model. Since this model is an image matching model, it requires pairs of images to be matched.
The raw outputs contain the list of keypoints detected by the keypoint detector as well as the list of matches with their corresponding
matching scores.
```python
from transformers import AutoImageProcessor, AutoModel
import torch
from PIL import Image
@ -53,70 +59,31 @@ model = AutoModel.from_pretrained("ETH-CVG/lightglue_superpoint")
inputs = processor(images, return_tensors="pt")
with torch.no_grad():
outputs = model(**inputs)
# Post-process to get keypoints and matches
image_sizes = [[(image.height, image.width) for image in images]]
processed_outputs = processor.post_process_keypoint_matching(outputs, image_sizes, threshold=0.2)
```
</hfoption>
</hfoptions>
You can use the `post_process_keypoint_matching` method from the `LightGlueImageProcessor` to get the keypoints and matches in a readable format:
```python
image_sizes = [[(image.height, image.width) for image in images]]
outputs = processor.post_process_keypoint_matching(outputs, image_sizes, threshold=0.2)
for i, output in enumerate(outputs):
print("For the image pair", i)
for keypoint0, keypoint1, matching_score in zip(
output["keypoints0"], output["keypoints1"], output["matching_scores"]
):
print(
f"Keypoint at coordinate {keypoint0.numpy()} in the first image matches with keypoint at coordinate {keypoint1.numpy()} in the second image with a score of {matching_score}."
)
```
## Notes
You can visualize the matches between the images by providing the original images as well as the outputs to this method:
```python
processor.plot_keypoint_matching(images, outputs)
```
- LightGlue is adaptive to the task difficulty. Inference is much faster on image pairs that are intuitively easy to match, for example, because of a larger visual overlap or limited appearance change.

```py
from transformers import AutoImageProcessor, AutoModel
import torch
from PIL import Image
import requests
processor = AutoImageProcessor.from_pretrained("ETH-CVG/lightglue_superpoint")
model = AutoModel.from_pretrained("ETH-CVG/lightglue_superpoint")
# LightGlue requires pairs of images
images = [image1, image2]
inputs = processor(images, return_tensors="pt")
outputs = model(**inputs)
# Extract matching information
keypoints0 = outputs.keypoints0 # Keypoints in first image
keypoints1 = outputs.keypoints1 # Keypoints in second image
matches = outputs.matches # Matching indices
matching_scores = outputs.matching_scores # Confidence scores
```
- The model outputs matching indices, keypoints, and confidence scores for each match, similar to SuperGlue but with improved efficiency.
- For better visualization and analysis, use the [`LightGlueImageProcessor.post_process_keypoint_matching`] method to get matches in a more readable format.
```py
# Process outputs for visualization
image_sizes = [[(image.height, image.width) for image in images]]
processed_outputs = processor.post_process_keypoint_matching(outputs, image_sizes, threshold=0.2)
for i, output in enumerate(processed_outputs):
print(f"For the image pair {i}")
for keypoint0, keypoint1, matching_score in zip(
output["keypoints0"], output["keypoints1"], output["matching_scores"]
):
print(f"Keypoint at {keypoint0.numpy()} matches with keypoint at {keypoint1.numpy()} with score {matching_score}")
```
- Visualize the matches between the images using the built-in plotting functionality.
```py
# Easy visualization using the built-in plotting method
processor.visualize_keypoint_matching(images, processed_outputs)
```

# 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.

> 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.*

alt="drawing" width="600"/>
<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.
```python
import torch

from transformers import LlavaNextProcessor
pipeline = pipeline(
task="image-text-to-text",
model="llava-hf/llava-v1.6-mistral-7b-hf",

torch_dtype=torch.bfloat16
)
messages = [

]
}
]
pipeline(text=messages, max_new_tokens=20, return_full_text=False)
processor = LlavaNextProcessor.from_pretrained("llava-hf/llava-v1.6-mistral-7b-hf")
conversation = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "Whats shown in this image?"},

},
{
"role": "user",
"content": [
{"type": "text", "text": "Describe the image in more details."},
],
},
]
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)
>>> "[INST] <image>\nWhat's shown in this image? [/INST] This image shows a red stop sign. [INST] Describe the image in more details. [/INST]"
```
</hfoption>
<hfoption id="AutoModel">
```python
import torch
import requests

from transformers import AutoProcessor, LlavaNextForConditionalGeneration
processor = AutoProcessor.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")

inputs = processor(image, prompt, return_tensors="pt").to("cuda")
output = model.generate(**inputs, max_new_tokens=100)
print(processor.decode(output[0], skip_special_tokens=True))
- If you want to construct a chat prompt yourself, below is a list of possible formats
.
[llava-v1.6-mistral-7b-hf](https://huggingface.co/llava-hf/llava-v1.6-mistral-7b-hf) requires the following format:
```bash

```
</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 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")
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/llava_next_ocr.png"
image = Image.open(requests.get(url, stream=True).raw)
conversation = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "What does this chart show?"},
],
},
]
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.
```py
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.

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()]
```

# Mimi
[Mimi](huggingface.co/papers/2410.00037) is a neural audio codec model with pretrained and quantized variants, designed for efficient speech representation and compression. The model operates at 1.1 kbps with a 12 Hz frame rate and uses a convolutional encoder-decoder architecture combined with a residual vector quantizer of 16 codebooks. Mimi outputs dual token streams i.e. semantic and acoustic to balance linguistic richness with high fidelity reconstruction. Key features include a causal streaming encoder for low-latency use, dual-path tokenization for flexible downstream generation, and integration readiness with large speech models like Moshi.

## Overview

The Mimi model was proposed in [Moshi: a speech-text foundation model for real-time dialogue](https://kyutai.org/Moshi.pdf) by Alexandre Défossez, Laurent Mazaré, Manu Orsini, Amélie Royer, Patrick Pérez, Hervé Jégou, Edouard Grave and Neil Zeghidour. Mimi is a high-fidelity audio codec model developed by the Kyutai team, that combines semantic and acoustic information into audio tokens running at 12Hz and a bitrate of 1.1kbps. In other words, it can be used to map audio waveforms into “audio tokens”, known as “codebooks”.
The example below demonstrates how to encode and decode audio with the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="AutoModel">
*We introduce Moshi, a speech-text foundation model and full-duplex spoken dialogue framework. Current systems for spoken dialogue rely on pipelines of independent components, namely voice activity detection, speech recognition, textual dialogue and text-to-speech. Such frameworks cannot emulate the experience of real conversations. First, their complexity induces a latency of several seconds between interactions. Second, text being the intermediate modality for dialogue, non-linguistic information that modifies meaning— such as emotion or non-speech sounds— is lost in the interaction. Finally, they rely on a segmentation into speaker turns, which does not take into account overlapping speech, interruptions and interjections. Moshi solves these independent issues altogether by casting spoken dialogue as speech-to-speech generation. Starting from a text language model backbone, Moshi generates speech as tokens from the residual quantizer of a neural audio codec, while modeling separately its own speech and that of the user into parallel streams. This allows for the removal of explicit speaker turns, and the modeling of arbitrary conversational dynamics. We moreover extend the hierarchical semantic-to-acoustic token generation of previous work to first predict time-aligned text tokens as a prefix to audio tokens. Not only this “Inner Monologue” method significantly improves the linguistic quality of generated speech, but we also illustrate how it can provide streaming speech recognition and text-to-speech. Our resulting model is the first real-time full-duplex spoken large language model, with a theoretical latency of 160ms, 200ms in practice, and is available at github.com/kyutai-labs/moshi.*
Its architecture is based on [Encodec](model_doc/encodec) with several major differences:
* it uses a much lower frame-rate.
* it uses additional transformers for encoding and decoding for better latent contextualization
* it uses a different quantization scheme: one codebook is dedicated to semantic projection.

However, one can shrink down the size of the model using [quantization](../quantization). If the model is quantized to 4 bits (or half a byte per parameter), about 228 GB of RAM is required.

## Shrinking down Mixtral using quantization
As the Mixtral model has 45 billion parameters, that would require about 90GB of GPU RAM in half precision (float16), since each parameter is stored in 2 bytes. However, one can shrink down the size of the model using [quantization](../quantization). If the model is quantized to 4 bits (or half a byte per parameter), a single A100 with 40GB of RAM is enough to fit the entire model, as in that case only about 27 GB of RAM is required.

# MM Grounding DINO
[MM Grounding DINO](https://arxiv.org/abs/2401.02361) model was proposed in [An Open and Comprehensive Pipeline for Unified Object Grounding and Detection](https://arxiv.org/abs/2401.02361) by Xiangyu Zhao, Yicheng Chen, Shilin Xu, Xiangtai Li, Xinjiang Wang, Yining Li, Haian Huang>.
MM Grounding DINO improves upon the [Grounding DINO](https://huggingface.co/docs/transformers/model_doc/grounding-dino) by improving the contrastive class head and removing the parameter sharing in the decoder, improving zero-shot detection performance on both COCO (50.6(+2.2) AP) and LVIS (31.9(+11.8) val AP and 41.4(+12.6) minival AP).
You can find all the original MM Grounding DINO checkpoints under the [MM Grounding DINO](https://huggingface.co/collections/openmmlab-community/mm-grounding-dino-688cbde05b814c4e2832f9df) collection. This model also supports LLMDet inference. You can find LLMDet checkpoints under the [LLMDet](https://huggingface.co/collections/iSEE-Laboratory/llmdet-688475906dc235d5f1dc678e) collection.

# ModernBERT Decoder
ModernBERT Decoder has the same architecture as [ModernBERT](https://huggingface.co/papers/2412.13663) but it is trained from scratch with a causal language modeling objective from the [Ettin paper](https://huggingface.co/papers/2507.11412). This allows for using the same architecture to compare encoders and decoders. This model is the decoder architecture implementation of ModernBERT, designed for autoregressive text generation tasks.
ModernBERT Decoder uses sliding window attention and rotary positional embeddings for efficiency and to handle longer sequences.
You can find all the original ModernBERT Decoder checkpoints under the [jhu-clsp](https://huggingface.co/collections/jhu-clsp/encoders-vs-decoders-the-ettin-suite-686303e16142257eed8e6aeb) collection.

The mT5 model was presented in [mT5: A massively multilingual pre-trained text-to-text transformer](https://huggingface.co/papers/2010.11934) by Linting Xue, Noah Constant, Adam Roberts, Mihir Kale, Rami Al-Rfou, Aditya
Siddhant, Aditya Barua, Colin Raffel.

<hfoptions id="usage">
<hfoption id="Pipeline">
*The recent "Text-to-Text Transfer Transformer" (T5) leveraged a unified text-to-text format and scale to attain
state-of-the-art results on a wide variety of English-language NLP tasks. In this paper, we introduce mT5, a
multilingual variant of T5 that was pre-trained on a new Common Crawl-based dataset covering 101 languages. We detail
the design and modified training of mT5 and demonstrate its state-of-the-art performance on many multilingual
benchmarks. We also describe a simple technique to prevent "accidental translation" in the zero-shot setting, where a
generative model chooses to (partially) translate its prediction into the wrong language. All of the code and model
checkpoints used in this work are publicly available.*
```python
import torch
from transformers import pipeline
Note: mT5 was only pre-trained on [mC4](https://huggingface.co/datasets/mc4) excluding any supervised training.
Therefore, this model has to be fine-tuned before it is usable on a downstream task, unlike the original T5 model.
Since mT5 was pre-trained unsupervisedly, there's no real advantage to using a task prefix during single-task
fine-tuning. If you are doing multi-task fine-tuning, you should use a prefix.

# OLMoE
## Overview
[OLMoE](https://huggingface.co/papers/2409.02060) is a sparse Mixture-of-Experts (MoE) language model with 7B parameters but only 1B parameters are used per input token. It has similar inference costs as dense models but trains ~3x faster. OLMoE uses fine-grained routing with 64 small experts in each layer and uses a dropless token-based routing algorithm.
The OLMoE model was proposed in [OLMoE: Open Mixture-of-Experts Language Models](https://huggingface.co/papers/2409.02060) by Niklas Muennighoff, Luca Soldaini, Dirk Groeneveld, Kyle Lo, Jacob Morrison, Sewon Min, Weijia Shi, Pete Walsh, Oyvind Tafjord, Nathan Lambert, Yuling Gu, Shane Arora, Akshita Bhagia, Dustin Schwenk, David Wadden, Alexander Wettig, Binyuan Hui, Tim Dettmers, Douwe Kiela, Ali Farhadi, Noah A. Smith, Pang Wei Koh, Amanpreet Singh, Hannaneh Hajishirzi.
You can find all the original OLMoE checkpoints under the [OLMoE](https://huggingface.co/collections/allenai/olmoe-november-2024-66cf678c047657a30c8cd3da) collection.
OLMoE is a series of **O**pen **L**anguage **Mo**dels using sparse **M**ixture-**o**f-**E**xperts designed to enable the science of language models. We release all code, checkpoints, logs, and details involved in training these models.

The abstract from the paper is the following:
The example below demonstrates how to generate text with [`Pipeline`] or the [`AutoModel`] class.
*We introduce OLMoE, a fully open, state-of-the-art language model leveraging sparse Mixture-of-Experts (MoE). OLMoE-1B-7B has 7 billion (B) parameters but uses only 1B per input token. We pretrain it on 5 trillion tokens and further adapt it to create OLMoE-1B-7B-Instruct. Our models outperform all available models with similar active parameters, even surpassing larger ones like Llama2-13B-Chat and DeepSeekMoE-16B. We present various experiments on MoE training, analyze routing in our model showing high specialization, and open-source all aspects of our work: model weights, training data, code, and logs.*

# OPT
[OPT](https://huggingface.co/papers/2205.01068) is a suite of open-source decoder-only pre-trained transformers whose parameters range from 125M to 175B. OPT models are designed for casual language modeling and aim to enable responsible and reproducible research at scale. OPT-175B is comparable in performance to GPT-3 with only 1/7th the carbon footprint.

The OPT model was proposed in [Open Pre-trained Transformer Language Models](https://huggingface.co/papers/2205.01068) by Meta AI.
OPT is a series of open-sourced large causal language models which perform similar in performance to GPT3.
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line.
The abstract from the paper is the following:
*Large language models, which are often trained for hundreds of thousands of compute days, have shown remarkable capabilities for zero- and few-shot learning. Given their computational cost, these models are difficult to replicate without significant capital. For the few that are available through APIs, no access is granted to the full model weights, making them difficult to study. We present Open Pre-trained Transformers (OPT), a suite of decoder-only pre-trained transformers ranging from 125M to 175B parameters, which we aim to fully and responsibly share with interested researchers. We show that OPT-175B is comparable to GPT-3, while requiring only 1/7th the carbon footprint to develop. We are also releasing our logbook detailing the infrastructure challenges we faced, along with code for experimenting with all of the released models.*

This model was contributed by [Arthur Zucker](https://huggingface.co/ArthurZ), [Younes Belkada](https://huggingface.co/ybelkada), and [Patrick Von Platen](https://huggingface.co/patrickvonplaten).
The original code can be found [here](https://github.com/facebookresearch/metaseq).
pipeline = pipeline(task="text-generation", model="facebook/opt-125m", torch_dtype=torch.float16, device=0)
pipeline("Once upon a time, in a land far, far away,", max_length=50, num_return_sequences=1)
```
Tips:
- OPT has the same architecture as [`BartDecoder`].
- Contrary to GPT2, OPT adds the EOS token `</s>` to the beginning of every prompt.

<hfoption id="AutoModel">
```py

from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda"
model = AutoModelForCausalLM.from_pretrained("facebook/opt-350m", torch_dtype=torch.float16, attn_implementation="sdpa")
tokenizer = AutoTokenizer.from_pretrained("facebook/opt-350m")
prompt = ("Once upon a time, in a land far, far away, ")
model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
model.to(device)
generated_ids = model.generate(**model_inputs, max_new_tokens=30, do_sample=False)
tokenizer.batch_decode(generated_ids)[0]
```
</hfoption>
<hfoption id="transformers CLI">
```py
echo -e "Plants create energy through a process known as" | transformers run --task text-generation --model facebook/opt-125m --device 0
```
</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 quantize the weights to 8-bits.
```py
import torch
from transformers import BitsAndBytesConfig, AutoTokenizer, AutoModelForCausalLM
device = "cuda"
bnb_config = BitsAndBytesConfig(load_in_8bit=True)
model = AutoModelForCausalLM.from_pretrained("facebook/opt-13b", torch_dtype=torch.float16, attn_implementation="sdpa", quantization_config=bnb_config)
tokenizer = AutoTokenizer.from_pretrained("facebook/opt-13b")
prompt = ("Once upon a time, in a land far, far away, ")
model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
model.to(device)
generated_ids = model.generate(**model_inputs, max_new_tokens=30, do_sample=False)
tokenizer.batch_decode(generated_ids)[0]
```
## Notes
- OPT adds an `EOS` token `</s>` to the beginning of every prompt.
- The `head_mask` argument is ignored if the attention implementation isn't `"eager"`. Set `attn_implementation="eager"` to enable the `head_mask`.
> [!NOTE]
> The `head_mask` argument is ignored when using all attention implementation other than "eager". If you have a `head_mask` and want it to have effect, load the model with `XXXModel.from_pretrained(model_id, attn_implementation="eager")`

## Combining OPT and Flash Attention 2
First, make sure to install the latest version of Flash Attention 2 to include the sliding window attention feature.
```bash
pip install -U flash-attn --no-build-isolation
```
Make also sure that you have a hardware that is compatible with Flash-Attention 2. Read more about it in the official documentation of flash-attn repository. Make also sure to load your model in half-precision (e.g. `torch.float16``)
To load and run a model using Flash Attention 2, refer to the snippet below:
```python
>>> import torch
>>> from transformers import OPTForCausalLM, GPT2Tokenizer
>>> device = "cuda" # the device to load the model onto
>>> model = OPTForCausalLM.from_pretrained("facebook/opt-350m", torch_dtype=torch.float16, attn_implementation="flash_attention_2")
>>> tokenizer = GPT2Tokenizer.from_pretrained("facebook/opt-350m")
>>> prompt = ("A chat between a curious human and the Statue of Liberty.\n\nHuman: What is your name?\nStatue: I am the "
"Statue of Liberty.\nHuman: Where do you live?\nStatue: New York City.\nHuman: How long have you lived "
"there?")
>>> model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
>>> model.to(device)
>>> generated_ids = model.generate(**model_inputs, max_new_tokens=30, do_sample=False)
>>> tokenizer.batch_decode(generated_ids)[0]
'</s>A chat between a curious human and the Statue of Liberty.\n\nHuman: What is your name?\nStatue: I am the Statue of Liberty.\nHuman: Where do you live?\nStatue: New York City.\nHuman: How long have you lived there?\nStatue: I have lived here for about a year.\nHuman: What is your favorite place to eat?\nStatue: I love'
```
### Expected speedups
Below is an expected speedup diagram that compares pure inference time between the native implementation in transformers using `facebook/opt-2.7b` checkpoint and the Flash Attention 2 version of the model using two different sequence lengths.

### Using Scaled Dot Product Attention (SDPA)
PyTorch includes a native scaled dot-product attention (SDPA) operator as part of `torch.nn.functional`. This function
encompasses several implementations that can be applied depending on the inputs and the hardware in use. See the
[official documentation](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html)
or the [GPU Inference](https://huggingface.co/docs/transformers/main/en/perf_infer_gpu_one#pytorch-scaled-dot-product-attention)
page for more information.
SDPA is used by default for `torch>=2.1.1` when an implementation is available, but you may also set
`attn_implementation="sdpa"` in `from_pretrained()` to explicitly request SDPA to be used.
```python
from transformers import OPTForCausalLM
model = OPTForCausalLM.from_pretrained("facebook/opt-350m", torch_dtype=torch.float16, attn_implementation="sdpa")
...
```
For the best speedups, we recommend loading the model in half-precision (e.g. `torch.float16` or `torch.bfloat16`).
On a local benchmark (L40S-45GB, PyTorch 2.4.0, OS Debian GNU/Linux 11) using `float16` with
[facebook/opt-350m](https://huggingface.co/facebook/opt-350m), we saw the
following speedups during training and inference.

# 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.*

# Phi4 Multimodal
## Phi4 Multimodal
## Overview
[Phi4 Multimodal](https://huggingface.co/papers/2503.01743) is a multimodal model capable of text, image, and speech and audio inputs or any combination of these. It features a mixture of LoRA adapters for handling different inputs, and each input is routed to the appropriate encoder.
Phi4 Multimodal is a lightweight open multimodal foundation model that leverages the language, vision, and speech research and datasets used for Phi-3.5 and 4.0 models. The model processes text, image, and audio inputs, generating text outputs, and comes with 128K token context length. The model underwent an enhancement process, incorporating both supervised fine-tuning, direct preference optimization and RLHF (Reinforcement Learning from Human Feedback) to support precise instruction adherence and safety measures. The languages that each modal supports are the following:

# SuperGlue
[SuperGlue](https://huggingface.co/papers/1911.11763) is a neural network that matches two sets of local features by jointly finding correspondences and rejecting non-matchable points. Assignments are estimated by solving a differentiable optimal transport problem, whose costs are predicted by a graph neural network. SuperGlue introduces a flexible context aggregation mechanism based on attention, enabling it to reason about the underlying 3D scene and feature assignments jointly. Paired with the [SuperPoint model](https://huggingface.co/magic-leap-community/superpoint), it can be used to match two images and estimate the pose between them. This model is useful for tasks such as image matching, homography estimation, etc.

```py
*This paper introduces SuperGlue, a neural network that matches two sets of local features by jointly finding correspondences
and rejecting non-matchable points. Assignments are estimated by solving a differentiable optimal transport problem, whose costs
are predicted by a graph neural network. We introduce a flexible context aggregation mechanism based on attention, enabling
SuperGlue to reason about the underlying 3D scene and feature assignments jointly. Compared to traditional, hand-designed heuristics,
our technique learns priors over geometric transformations and regularities of the 3D world through end-to-end training from image
pairs. SuperGlue outperforms other learned approaches and achieves state-of-the-art results on the task of pose estimation in
challenging real-world indoor and outdoor environments. The proposed method performs matching in real-time on a modern GPU and
can be readily integrated into modern SfM or SLAM systems. The code and trained weights are publicly available at this [URL](https://github.com/magicleap/SuperGluePretrainedNetwork).*
## How to use
Here is a quick example of using the model. Since this model is an image matching model, it requires pairs of images to be matched.
The raw outputs contain the list of keypoints detected by the keypoint detector as well as the list of matches with their corresponding
matching scores.

You can use the `post_process_keypoint_matching` method from the `SuperGlueImageProcessor` to get the keypoints and matches in a more readable format:

for i, output in enumerate(outputs):
print("For the image pair", i)

):
print(
f"Keypoint at coordinate {keypoint0.numpy()} in the first image matches with keypoint at coordinate {keypoint1.numpy()} in the second image with a score of {matching_score}."
)
- SuperGlue performs feature matching between two images simultaneously, requiring pairs of images as input.
```
```python
from transformers import AutoImageProcessor, AutoModel

keypoints0 = outputs.keypoints0 # Keypoints in first image
keypoints1 = outputs.keypoints1 # Keypoints in second image
matches = outputs.matches # Matching indices
matching_scores = outputs.matching_scores # Confidence scores
```
From the outputs, you can visualize the matches between the two images using the following code:
```python
import matplotlib.pyplot as plt
import numpy as np
- The model outputs matching indices, keypoints, and confidence scores for each match.
- For better visualization and analysis, use the [`SuperGlueImageProcessor.post_process_keypoint_matching`] method to get matches in a more readable format.
