But if you're replying to a comment that happened some comments back it's always a good practice to quote just the relevant lines you're replying it. The `>` is used for quoting, or you can always use the menu to do so. For example your editor box will look like:
```
> How big is your gpu cluster?
> How big is your GPU cluster?
Our cluster is made of 256 gpus.
Our cluster is made of 256 GPUs.
```
If you are addressing multiple comments, quote the relevant parts of each before your answer. Some people use the same comment to do multiple replies, others separate them into separate comments. Either way works. The latter approach helps for linking to a specific comment.

In this folder you will find various docker files, and some subfolders.
- dockerfiles (ex: `consistency.dockerfile`) present under `~/docker` are used for our "fast" CIs. You should be able to use them for tasks that only need CPU. For example `torch-light` is a very light weights container (703MiB).
- subfloder contain dockerfiles used for our `slow` CIs, which *can* be used for GPU tasks, but they are **BIG** as they were not specifically designed for a single model / single task. Thus the `~/docker/transformers-pytorch-gpu` includes additional dependencies to allow us to run ALL model tests (say `librosa` or `tesseract`, which you do not need to run LLMs)

Thus the `~/docker/transformers-pytorch-gpu` includes additional dependencies to allow us to run ALL model tests (say `librosa` or `tesseract`, which you do not need to run LLMs)
Note that in both case, you need to run `uv pip install -e .`, which should take around 5 seconds. We do it outside the dockerfile for the need of our CI: we checkout a new branch each time, and the `transformers` code is thus updated.
We are open to contribution, and invite the community to create dockerfiles with potential arguments that properly choose extras depending on the model's dependencies! :hugs:

# Attention Interface
This page describes how to use the `AttentionInterface` in order to register custom attention functions to use with
supported models.
## Customizing attention function
Most recent models can now switch from one attention function used in the Attention layer to the other, thanks to a simple mapping.
By default, we provide the implementation for [`sdpa`](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html),
[`flash_attention_2`](https://github.com/Dao-AILab/flash-attention) and [`flex_attention`](https://pytorch.org/docs/stable/nn.attention.flex_attention.html#module-torch.nn.attention.flex_attention)
as well as `eager`, which is a simple matrix multiplication without any optimization on top.
This is the setting you can usually choose when instantiating a model:
```python
from transformers import AutoModelForCausalLM
model_id = "meta-llama/Llama-3.2-1B"
# Here, using flash attention as an example
model = AutoModelForCausalLM.from_pretrained(model_id, attn_implementation="flash_attention_2")
```
But what if you wanted to create your own attention function? Or simply play around with existing ones, adding
a few statements here and there? You can now do so with the `AttentionInterface`! Here is an example:
```python
from transformers import AutoModelForCausalLM, AttentionInterface
from transformers.integrations.sdpa_attention import sdpa_attention_forward
import torch
model_id = "meta-llama/Llama-3.2-1B"
def my_new_sdpa(*args, **kwargs):
print("I just entered the attention computation")
return sdpa_attention_forward(*args, **kwargs)
AttentionInterface.register("my_new_sdpa", my_new_sdpa)
model = AutoModelForCausalLM.from_pretrained(model_id, attn_implementation="my_new_sdpa")
# Try running the forward with the new attention function
model(torch.ones(1, 5, dtype=int))
```
You will see it prints "I just entered the attention computation" as many times as there are layers in the model (with this example, 16 times).
## Dynamically switching attention function
You could dynamically change the model's attention function as well, by overriding the `config._attn_implementation` field:
```python
# Back to use original sdpa implementation
model.config._attn_implementation = "sdpa"
model(torch.ones(1, 5, dtype=int))
```
and it will stop printing the statements, as it now uses the `sdpa` attention.
This allows to quickly change an attention function, without needing to reload the model!
## What about new args needed in my custom attention function?
But indeed, what if the new function requires a new arg to be properly used? It's no issue! Models supporting the
`AttentionInterface` propagate kwargs all the way to the Attention layers, and to the used attention function. That way,
you can simply pass the arg (as a kwargs, i.e. you need to qualify the name of the arg) in the model's forward, and it will be correctly used in the attention. However, custom attention functions have some limitations. In particular, it must follow the signature and return format of other attention functions, i.e.
```python
from transformers import AutoModelForCausalLM, AttentionInterface
from transformers.integrations.sdpa_attention import sdpa_attention_forward
import torch
def custom_attention(
module: torch.nn.Module, # required arg
query: torch.Tensor, # required arg
key: torch.Tensor, # required arg
value: torch.Tensor, # required arg
attention_mask: Optional[torch.Tensor], # required arg
a_new_kwargs = None, # You can now add as many kwargs as you need
another_new_kwargs = None, # You can now add as many kwargs as you need
**kwargs, # You need to accept **kwargs as models will pass other args
) -> Tuple[torch.Tensor, Optional[torch.Tensor]]
... # do your magic!
return attn_output, attn_weights # attn_weights are optional here
AttentionInterface.register("custom", custom_attention)
model = AutoModelForCausalLM.from_pretrained(model_id, attn_implementation="custom")
# Forward pass with the new kwargs
model(torch.ones(1, 5, dtype=int), a_new_kwargs=..., another_new_kwargs=...)
```
If in doubt about what args/kwargs a given model sends to the attention function, simply check that model's modeling code on [GitHub](https://github.com/huggingface/transformers/tree/main/src/transformers/models)!
## Accessing current available implementations
Most of the time, you will simply need to `register` a new function. If, however, you need to access an existing one,
and/or perform a few checks, the prefered way is to use the global `ALL_ATTENTION_FUNCTIONS`. It behaves the same way you
would expect from a usual Python dictionary:
```python
>>> from transformers.modeling_utils import ALL_ATTENTION_FUNCTIONS
>>> list(ALL_ATTENTION_FUNCTIONS.keys())
>>> ['flash_attention_2', 'flex_attention', 'sdpa']
>>> ALL_ATTENTION_FUNCTIONS["sdpa"]
>>> <function transformers.integrations.sdpa_attention.sdpa_attention_forward>
>>> ALL_ATTENTION_FUNCTIONS.get("sdpa", None)
>>> <function transformers.integrations.sdpa_attention.sdpa_attention_forward>
# You can also globally `register` a new function directly on it
>>> ALL_ATTENTION_FUNCTIONS.register("new_func", new_func)
```

## Overview
# CLIP
The CLIP model was proposed in [Learning Transferable Visual Models From Natural Language Supervision](https://arxiv.org/abs/2103.00020) by Alec Radford, Jong Wook Kim, Chris Hallacy, Aditya Ramesh, Gabriel Goh,
Sandhini Agarwal, Girish Sastry, Amanda Askell, Pamela Mishkin, Jack Clark, Gretchen Krueger, Ilya Sutskever. CLIP
(Contrastive Language-Image Pre-Training) is a neural network trained on a variety of (image, text) pairs. It can be
instructed in natural language to predict the most relevant text snippet, given an image, without directly optimizing
for the task, similarly to the zero-shot capabilities of GPT-2 and 3.
[CLIP](https://huggingface.co/papers/2103.00020) is a is a multimodal vision and language model motivated by overcoming the fixed number of object categories when training a computer vision model. CLIP learns about images directly from raw text by jointly training on 400M (image, text) pairs. Pretraining on this scale enables zero-shot transfer to downstream tasks. CLIP uses an image encoder and text encoder to get visual features and text features. Both features are projected to a latent space with the same number of dimensions and their dot product gives a similarity score.
The abstract from the paper is the following:
You can find all the original CLIP checkpoints under the [OpenAI](https://huggingface.co/openai?search_models=clip) organization.
*State-of-the-art computer vision systems are trained to predict a fixed set of predetermined object categories. This
restricted form of supervision limits their generality and usability since additional labeled data is needed to specify
any other visual concept. Learning directly from raw text about images is a promising alternative which leverages a
much broader source of supervision. We demonstrate that the simple pre-training task of predicting which caption goes
with which image is an efficient and scalable way to learn SOTA image representations from scratch on a dataset of 400
million (image, text) pairs collected from the internet. After pre-training, natural language is used to reference
learned visual concepts (or describe new ones) enabling zero-shot transfer of the model to downstream tasks. We study
the performance of this approach by benchmarking on over 30 different existing computer vision datasets, spanning tasks
such as OCR, action recognition in videos, geo-localization, and many types of fine-grained object classification. The
model transfers non-trivially to most tasks and is often competitive with a fully supervised baseline without the need
for any dataset specific training. For instance, we match the accuracy of the original ResNet-50 on ImageNet zero-shot
without needing to use any of the 1.28 million training examples it was trained on. We release our code and pre-trained
model weights at this https URL.*

This model was contributed by [valhalla](https://huggingface.co/valhalla). The original code can be found [here](https://github.com/openai/CLIP).
The example below demonstrates how to calculate similarity scores between multiple text descriptions and an image with [`Pipeline`] or the [`AutoModel`] class.
## Usage tips and example
<hfoptions id="usage">
<hfoption id="Pipeline">
CLIP is a multi-modal vision and language model. It can be used for image-text similarity and for zero-shot image
classification. CLIP uses a ViT like transformer to get visual features and a causal language model to get the text
features. Both the text and visual features are then projected to a latent space with identical dimension. The dot
product between the projected image and text features is then used as a similar score.
```py
import torch
from transformers import pipeline
To feed images to the Transformer encoder, each image is split into a sequence of fixed-size non-overlapping patches,
which are then linearly embedded. A [CLS] token is added to serve as representation of an entire image. The authors
also add absolute position embeddings, and feed the resulting sequence of vectors to a standard Transformer encoder.
The [`CLIPImageProcessor`] can be used to resize (or rescale) and normalize images for the model.
The [`CLIPTokenizer`] is used to encode the text. The [`CLIPProcessor`] wraps
[`CLIPImageProcessor`] and [`CLIPTokenizer`] into a single instance to both
encode the text and prepare the images. The following example shows how to get the image-text similarity scores using
[`CLIPProcessor`] and [`CLIPModel`].
```python
>>> from PIL import Image
>>> import requests
>>> from transformers import CLIPProcessor, CLIPModel
>>> model = CLIPModel.from_pretrained("openai/clip-vit-base-patch32")
>>> processor = CLIPProcessor.from_pretrained("openai/clip-vit-base-patch32")
>>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
>>> image = Image.open(requests.get(url, stream=True).raw)
>>> inputs = processor(text=["a photo of a cat", "a photo of a dog"], images=image, return_tensors="pt", padding=True)
>>> outputs = model(**inputs)
>>> logits_per_image = outputs.logits_per_image # this is the image-text similarity score
>>> probs = logits_per_image.softmax(dim=1) # we can take the softmax to get the label probabilities
clip = pipeline(
task="zero-shot-image-classification",
model="openai/clip-vit-base-patch32",
torch_dtype=torch.bfloat16,
device=0
)
labels = ["a photo of a cat", "a photo of a dog", "a photo of a car"]
clip("http://images.cocodataset.org/val2017/000000039769.jpg", candidate_labels=labels)
```
</hfoption>
<hfoption id="AutoModel">
### Combining CLIP and Flash Attention 2
```py
import requests
import torch
from PIL import Image
from transformers import AutoProcessor, AutoModel
First, make sure to install the latest version of Flash Attention 2.
model = AutoModel.from_pretrained("openai/clip-vit-base-patch32", torch_dtype=torch.bfloat16, attn_implementation="sdpa")
processor = AutoProcessor.from_pretrained("openai/clip-vit-base-patch32")
```bash
pip install -U flash-attn --no-build-isolation
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
labels = ["a photo of a cat", "a photo of a dog", "a photo of a car"]
inputs = processor(text=labels, images=image, return_tensors="pt", padding=True)
outputs = model(**inputs)
logits_per_image = outputs.logits_per_image
probs = logits_per_image.softmax(dim=1)
most_likely_idx = probs.argmax(dim=1).item()
most_likely_label = labels[most_likely_idx]
print(f"Most likely label: {most_likely_label} with probability: {probs[0][most_likely_idx].item():.3f}")
```
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`)
</hfoption>
</hfoptions>
<Tip warning={true}>
## Notes
For small batch sizes, you might notice a slowdown in your model when using flash attention. Refer to the section [Expected speedups with Flash Attention and SDPA](#Expected-speedups-with-Flash-Attention-and-SDPA) below and select an appropriate attention implementation.
</Tip>
To load and run a model using Flash Attention 2, refer to the snippet below:
```python
>>> import torch
>>> import requests
>>> from PIL import Image
>>> from transformers import CLIPProcessor, CLIPModel
>>> device = "cuda"
>>> torch_dtype = torch.float16
>>> model = CLIPModel.from_pretrained(
... "openai/clip-vit-base-patch32",
... attn_implementation="flash_attention_2",
... device_map=device,
... torch_dtype=torch_dtype,
... )
>>> processor = CLIPProcessor.from_pretrained("openai/clip-vit-base-patch32")
>>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
>>> image = Image.open(requests.get(url, stream=True).raw)
>>> inputs = processor(text=["a photo of a cat", "a photo of a dog"], images=image, return_tensors="pt", padding=True)
>>> inputs.to(device)
>>> with torch.no_grad():
... with torch.autocast(device):
... outputs = model(**inputs)
>>> logits_per_image = outputs.logits_per_image # this is the image-text similarity score
>>> probs = logits_per_image.softmax(dim=1) # we can take the softmax to get the label probabilities
>>> print(probs)
tensor([[0.9946, 0.0052]], device='cuda:0', dtype=torch.float16)
```
### 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 CLIPModel
model = CLIPModel.from_pretrained("openai/clip-vit-base-patch32", 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`).
### Expected speedups with Flash Attention and SDPA
On a local benchmark (NVIDIA A10G, PyTorch 2.3.1+cu121) with `float16`, we saw the following speedups during inference for `"openai/clip-vit-large-patch14"` checkpoint ([code](https://gist.github.com/qubvel/ac691a54e54f9fae8144275f866a7ff8)):

## Overview
# CodeLlama
The Code Llama model was proposed in [Code Llama: Open Foundation Models for Code](https://ai.meta.com/research/publications/code-llama-open-foundation-models-for-code/) by Baptiste Rozière, Jonas Gehring, Fabian Gloeckle, Sten Sootla, Itai Gat, Xiaoqing Ellen Tan, Yossi Adi, Jingyu Liu, Tal Remez, Jérémy Rapin, Artyom Kozhevnikov, Ivan Evtimov, Joanna Bitton, Manish Bhatt, Cristian Canton Ferrer, Aaron Grattafiori, Wenhan Xiong, Alexandre Défossez, Jade Copet, Faisal Azhar, Hugo Touvron, Louis Martin, Nicolas Usunier, Thomas Scialom, Gabriel Synnaeve.
[Code Llama](https://huggingface.co/papers/2308.12950) is a specialized family of large language models based on [Llama 2](./llama2) for coding tasks. It comes in different flavors - general code, Python-specific, and instruction-following variant - all available in 7B, 13B, 34B, and 70B parameters. Code Llama models can generate, explain, and even fill in missing parts of your code (called "infilling"). It can also handle very long contexts with stable generation up to 100k tokens, even though it was trained on sequences of 16K tokens.
The abstract from the paper is the following:
You can find all the original Code Llama checkpoints under the [Code Llama](https://huggingface.co/collections/meta-llama/code-llama-family-661da32d0a9d678b6f55b933) collection.
*We release Code Llama, a family of large language models for code based on Llama 2 providing state-of-the-art performance among open models, infilling capabilities, support for large input contexts, and zero-shot instruction following ability for programming tasks. We provide multiple flavors to cover a wide range of applications: foundation models (Code Llama), Python specializations (Code Llama - Python), and instruction-following models (Code Llama - Instruct) with 7B, 13B and 34B parameters each. All models are trained on sequences of 16k tokens and show improvements on inputs with up to 100k tokens. 7B and 13B Code Llama and Code Llama - Instruct variants support infilling based on surrounding content. Code Llama reaches state-of-the-art performance among open models on several code benchmarks, with scores of up to 53% and 55% on HumanEval and MBPP, respectively. Notably, Code Llama - Python 7B outperforms Llama 2 70B on HumanEval and MBPP, and all our models outperform every other publicly available model on MultiPL-E. We release Code Llama under a permissive license that allows for both research and commercial use.*

Check out all Code Llama model checkpoints [here](https://huggingface.co/models?search=code_llama) and the officially released ones in the [Meta Llama org](https://huggingface.co/meta-llama).
The example below demonstrates how to generate code with [`Pipeline`], or the [`AutoModel`], and from the command line.
This model was contributed by [ArthurZucker](https://huggingface.co/ArthurZ). The original code of the authors can be found [here](https://github.com/facebookresearch/llama).
<hfoptions id="usage">
<hfoption id="Pipeline">
```py
import torch
from transformers import pipeline
## Usage tips and examples
pipe = pipeline(
"text-generation",
model="meta-llama/CodeLlama-7b-hf",
torch_dtype=torch.float16,
device_map=0
)
<Tip warning={true}>
# basic code generation
result = pipe("# Function to calculate the factorial of a number\ndef factorial(n):", max_new_tokens=256)
print(result[0]['generated_text'])
The `Llama2` family models, on which Code Llama is based, were trained using `bfloat16`, but the original inference uses `float16`. Let's look at the different precisions:
# infilling
infill_result = pipe("def remove_non_ascii(s: str) -> str:\n \"\"\" <FILL_ME>\n return result", max_new_tokens=200)
print(infill_result[0]['generated_text'])
```
* `float32`: PyTorch convention on model initialization is to load models in `float32`, no matter with which `dtype` the model weights were stored. `transformers` also follows this convention for consistency with PyTorch. This will be picked by default. If you want the `AutoModel` API to load the checkpoints with the storage weights type, you must specify `torch_dtype="auto"`, e.g. `model = AutoModelForCausalLM.from_pretrained("path", torch_dtype = "auto")`.
* `bfloat16`: Code Llama was trained with this precision, so we recommend using it for further training or fine-tuning.
* `float16`: We recommend running inference using this precision, as it's usually faster than `bfloat16`, and evaluation metrics show no discernible degradation with respect to `bfloat16`. You can also run inference using `bfloat16`, and we recommend you check inference results with both `float16` and `bfloat16` after fine-tuning.
</hfoption>
<hfoption id="AutoModel">
As mentioned above, the `dtype` of the storage weights is mostly irrelevant unless you are using `torch_dtype="auto"` when initializing a model using. The reason is that the model will first be downloaded (using the `dtype` of the checkpoints online) and then will be casted to the default `dtype` of `torch` (becomes `torch.float32`). If there is a specified `torch_dtype`, it will be used instead.
```py
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
</Tip>
tokenizer = AutoTokenizer.from_pretrained("meta-llama/CodeLlama-7b-hf")
model = AutoModelForCausalLM.from_pretrained(
"meta-llama/CodeLlama-7b-hf",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
# basic code generation
prompt = "# Function to calculate the factorial of a number\ndef factorial(n):"
input_ids = tokenizer(prompt, return_tensors="pt").to("cuda")
Tips:
- The infilling task is supported out of the box. You should be using the `tokenizer.fill_token` where you want your input to be filled.
- The model conversion script is the same as for the `Llama2` family:
output = model.generate(
**input_ids,
max_new_tokens=256,
cache_implementation="static"
)
print(tokenizer.decode(output[0], skip_special_tokens=True))
Here is a sample usage:
# infilling
infill_prompt = "def remove_non_ascii(s: str) -> str:\n \"\"\" <FILL_ME>\n return result"
input_ids = tokenizer(infill_prompt, return_tensors="pt").to(model.device)
filled_output = model.generate(**input_ids, max_new_tokens=200)
filled_text = tokenizer.decode(filled_output[0], skip_special_tokens=True)
print(filled_text)
```
</hfoption>
<hfoption id="transformers-cli">
```bash
python src/transformers/models/llama/convert_llama_weights_to_hf.py \
--input_dir /path/to/downloaded/llama/weights --model_size 7B --output_dir /output/path
echo -e "# Function to calculate the factorial of a number\ndef factorial(n):" | transformers-cli run --task text-generation --model meta-llama/CodeLlama-7b-hf --device 0
```
Note that executing the script requires enough CPU RAM to host the whole model in float16 precision (even if the biggest versions
come in several checkpoints they each contain a part of each weight of the model, so we need to load them all in RAM).
</hfoption>
</hfoptions>
After conversion, the model and tokenizer can be loaded via:
Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
```python
>>> from transformers import LlamaForCausalLM, CodeLlamaTokenizer
The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to 4-bits.
>>> tokenizer = CodeLlamaTokenizer.from_pretrained("meta-llama/CodeLlama-7b-hf")
>>> model = LlamaForCausalLM.from_pretrained("meta-llama/CodeLlama-7b-hf")
>>> PROMPT = '''def remove_non_ascii(s: str) -> str:
... """ <FILL_ME>
... return result
... '''
>>> input_ids = tokenizer(PROMPT, return_tensors="pt")["input_ids"]
>>> generated_ids = model.generate(input_ids, max_new_tokens=128)
```py
# pip install bitsandbytes
import torch
from transformers import AutoModelForCausalLM, CodeLlamaTokenizer, BitsAndBytesConfig
>>> filling = tokenizer.batch_decode(generated_ids[:, input_ids.shape[1]:], skip_special_tokens = True)[0]

output = model.generate(**input_ids, max_new_tokens=200, cache_implementation="static")
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
If you only want the infilled part:
```python
>>> from transformers import pipeline
>>> import torch
Use the [AttentionMaskVisualizer](https://github.com/huggingface/transformers/blob/beb9b5b02246b9b7ee81ddf938f93f44cfeaad19/src/transformers/utils/attention_visualizer.py#L139) to better understand what tokens the model can and cannot attend to.
>>> generator = pipeline("text-generation",model="meta-llama/CodeLlama-7b-hf",torch_dtype=torch.float16, device_map="auto")
>>> generator('def remove_non_ascii(s: str) -> str:\n """ <FILL_ME>\n return result', max_new_tokens = 128)
[{'generated_text': 'def remove_non_ascii(s: str) -> str:\n """ <FILL_ME>\n return resultRemove non-ASCII characters from a string. """\n result = ""\n for c in s:\n if ord(c) < 128:\n result += c'}]
```py
from transformers.utils.attention_visualizer import AttentionMaskVisualizer
visualizer = AttentionMaskVisualizer("meta-llama/CodeLlama-7b-hf")
visualizer("""def func(a, b):
return a + b""")
```
Under the hood, the tokenizer [automatically splits by `<FILL_ME>`](https://huggingface.co/docs/transformers/main/model_doc/code_llama#transformers.CodeLlamaTokenizer.fill_token) to create a formatted input string that follows [the original training pattern](https://github.com/facebookresearch/codellama/blob/cb51c14ec761370ba2e2bc351374a79265d0465e/llama/generation.py#L402). This is more robust than preparing the pattern yourself: it avoids pitfalls, such as token glueing, that are very hard to debug. To see how much CPU and GPU memory you need for this model or others, try [this calculator](https://huggingface.co/spaces/hf-accelerate/model-memory-usage) which can help determine that value.

</div>
The LLaMA tokenizer is a BPE model based on [sentencepiece](https://github.com/google/sentencepiece). One quirk of sentencepiece is that when decoding a sequence, if the first token is the start of the word (e.g. "Banana"), the tokenizer does not prepend the prefix space to the string.
<Tip>
Code Llama has the same architecture as the `Llama2` models, refer to [Llama2's documentation page](llama2) for the API reference.
Find Code Llama tokenizer reference below.
</Tip>
## Notes
- Infilling is only available in the 7B and 13B base models, and not in the Python, Instruct, 34B, or 70B models.
- Use the `<FILL_ME>` token where you want your input to be filled. The tokenizer splits this token to create a formatted input string that follows the [original training pattern](https://github.com/facebookresearch/codellama/blob/cb51c14ec761370ba2e2bc351374a79265d0465e/llama/generation.py#L402). This is more robust than preparing the pattern yourself.
```py
from transformers import LlamaForCausalLM, CodeLlamaTokenizer
tokenizer = CodeLlamaTokenizer.from_pretrained("meta-llama/CodeLlama-7b-hf")
model = LlamaForCausalLM.from_pretrained("meta-llama/CodeLlama-7b-hf")
PROMPT = '''def remove_non_ascii(s: str) -> str:
""" <FILL_ME>
return result
'''
input_ids = tokenizer(PROMPT, return_tensors="pt")["input_ids"]
generated_ids = model.generate(input_ids, max_new_tokens=128)
filling = tokenizer.batch_decode(generated_ids[:, input_ids.shape[1]:], skip_special_tokens = True)[0]
print(PROMPT.replace("<FILL_ME>", filling))
```
- Use `bfloat16` for further training or fine-tuning and `float16` for inference.
- The `BOS` character is not used for infilling when encoding the prefix or suffix, but only at the beginning of each prompt.
- The tokenizer is a byte-pair encoding model based on [SentencePiece](https://github.com/google/sentencepiece). During decoding, if the first token is the start of the word (for example, “Banana”), the tokenizer doesnt prepend the prefix space to the string.

## Overview
The Cohere Command-R model was proposed in the blogpost [Command-R: Retrieval Augmented Generation at Production Scale](https://txt.cohere.com/command-r/) by the Cohere Team.
# Cohere
The abstract from the paper is the following:
Cohere Command-R is a 35B parameter multilingual large language model designed for long context tasks like retrieval-augmented generation (RAG) and calling external APIs and tools. The model is specifically trained for grounded generation and supports both single-step and multi-step tool use. It supports a context length of 128K tokens.
*Command-R is a scalable generative model targeting RAG and Tool Use to enable production-scale AI for enterprise. Today, we are introducing Command-R, a new LLM aimed at large-scale production workloads. Command-R targets the emerging “scalable” category of models that balance high efficiency with strong accuracy, enabling companies to move beyond proof of concept, and into production.*
You can find all the original Command-R checkpoints under the [Command Models](https://huggingface.co/collections/CohereForAI/command-models-67652b401665205e17b192ad) collection.
*Command-R is a generative model optimized for long context tasks such as retrieval augmented generation (RAG) and using external APIs and tools. It is designed to work in concert with our industry-leading Embed and Rerank models to provide best-in-class integration for RAG applications and excel at enterprise use cases. As a model built for companies to implement at scale, Command-R boasts:
- Strong accuracy on RAG and Tool Use
- Low latency, and high throughput
- Longer 128k context and lower pricing
- Strong capabilities across 10 key languages
- Model weights available on HuggingFace for research and evaluation
Checkout model checkpoints [here](https://huggingface.co/CohereForAI/c4ai-command-r-v01).
This model was contributed by [Saurabh Dash](https://huggingface.co/saurabhdash) and [Ahmet Üstün](https://huggingface.co/ahmetustun). The code of the implementation in Hugging Face is based on GPT-NeoX [here](https://github.com/EleutherAI/gpt-neox).

## Usage tips
The example below demonstrates how to generate text with [`Pipeline`] or the [`AutoModel`], and from the command line.
<Tip warning={true}>
The checkpoints uploaded on the Hub use `torch_dtype = 'float16'`, which will be
used by the `AutoModel` API to cast the checkpoints from `torch.float32` to `torch.float16`.
The `dtype` of the online weights is mostly irrelevant unless you are using `torch_dtype="auto"` when initializing a model using `model = AutoModelForCausalLM.from_pretrained("path", torch_dtype = "auto")`. The reason is that the model will first be downloaded ( using the `dtype` of the checkpoints online), then it will be casted to the default `dtype` of `torch` (becomes `torch.float32`), and finally, if there is a `torch_dtype` provided in the config, it will be used.
Training the model in `float16` is not recommended and is known to produce `nan`; as such, the model should be trained in `bfloat16`.
</Tip>
The model and tokenizer can be loaded via:
<hfoptions id="usage">
<hfoption id="Pipeline">
```python
# pip install transformers

device=0
)

```
</hfoption>

print(tokenizer.decode(output[0], skip_special_tokens=True))
```
- When using Flash Attention 2 via `attn_implementation="flash_attention_2"`, don't pass `torch_dtype` to the `from_pretrained` class method and use Automatic Mixed-Precision training. When using `Trainer`, it is simply specifying either `fp16` or `bf16` to `True`. Otherwise, make sure you are using `torch.autocast`. This is required because the Flash Attention only support `fp16` and `bf16` data type.

# DeepSeek-V3
## Overview
The DeepSeek-V3 model was proposed in [DeepSeek-V3 Technical Report](https://arxiv.org/abs/2412.19437) by DeepSeek-AI Team.
The abstract from the paper is the following:
We present DeepSeek-V3, a strong Mixture-of-Experts (MoE) language model with 671B total parameters with 37B activated for each token. To achieve efficient inference and cost-effective training, DeepSeek-V3 adopts Multi-head Latent Attention (MLA) and DeepSeekMoE architectures, which were thoroughly validated in DeepSeek-V2. Furthermore, DeepSeek-V3 pioneers an auxiliary-loss-free strategy for load balancing and sets a multi-token prediction training objective for stronger performance. We pre-train DeepSeek-V3 on 14.8 trillion diverse and high-quality tokens, followed by Supervised Fine-Tuning and Reinforcement Learning stages to fully harness its capabilities. Comprehensive evaluations reveal that DeepSeek-V3 outperforms other open-source models and achieves performance comparable to leading closed-source models. Despite its excellent performance, DeepSeek-V3 requires only 2.788M H800 GPU hours for its full training. In addition, its training process is remarkably stable. Throughout the entire training process, we did not experience any irrecoverable loss spikes or perform any rollbacks. The model checkpoints are available at https://github.com/deepseek-ai/DeepSeek-V3.
## Limitations and call for contribution!
We are super happy to make this code community-powered, and would love to see how you can best optimize the following:
- current implementation uses the "naive" attention compution (so not really MLA)
- current implementation loops through the experts. This should be replaced. Pointers to use `get_packed_weights` from `intetrations/tensor_parallel`.
- current implementation uses the eleuther formula for ROPE, using the orginal one would be more efficient! (should still follow our API)
- static cache is not supported (this should be just a generation config issue / config shape issues)
### 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.
You can run the model in `FP8` automatically, using 2 nodes of 8 H100 should be more than enough!
```python
# `run_deepseek_v1.py`
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
torch.manual_seed(30)
tokenizer = AutoTokenizer.from_pretrained("deepseek-r1")
chat = [
{"role": "user", "content": "Hello, how are you?"},
{"role": "assistant", "content": "I'm doing great. How can I help you today?"},
{"role": "user", "content": "I'd like to show off how chat templating works!"},
]
model = AutoModelForCausalLM.from_pretrained("deepseek-r1", device_map="auto", torch_dtype=torch.bfloat16)
inputs = tokenizer.apply_chat_template(chat, tokenize=True, add_generation_prompt=True, return_tensors="pt").to(model.device)
import time
start = time.time()
outputs = model.generate(inputs, max_new_tokens=50)
print(tokenizer.batch_decode(outputs))
print(time.time()-start)
```

<Assistant><think>
Okay, the user wants to demonstrate how chat templating works. Let me break down what that means. Chat templating is about structuring the conversation data, especially for models that need specific input formats. Maybe they're referring to something like how messages are formatted with roles (user, assistant, system) in APIs like OpenAI.
First, I should explain what chat templating is. It's the process of formatting conversation data into a structured format that the model can understand. This usually includes roles and content. For example, user messages, assistant responses, and system messages each have their own role tags.
They might want an example. Let me think of a simple conversation. The user says "Hello, how are you?" and the assistant responds "I'm doing great. How can I help you today?" Then the user follows up with wanting to show off chat templating. So the example should include the history and the new message.
In some frameworks, like Hugging Face's Transformers, chat templates are applied using Jinja2 templates. The template might look something like combining system messages, then looping through user and assistant messages with appropriate tags. For instance, using {% for message in messages %} and assigning roles like <|user|>, <|assistant|>, etc.
I should structure the example with the messages array, showing each role and content. Then apply a hypothetical template to convert that into a formatted string the model uses. Also, mention that different models have different templating requirements, like using special tokens or varying role labels.
Wait, the user mentioned "chat templating" in the context of showing off. Maybe they want a practical example they can present. So providing a code snippet or a structured data example would be helpful. Let me outline a typical messages array and then the templated output.
Also, it's important to note that proper templating ensures the model knows the conversation flow, which is crucial for generating coherent responses. Maybe include a note about why it's important, like maintaining context and role-specific processing.
Let me check if there are any common mistakes or things to avoid. For example, not closing tags properly, or mismatching roles. But maybe that's too detailed unless the user asks. Focus on the positive example first.
Putting it all together, the response should have an example messages array, the applied template, and the final formatted string. Maybe use angle brackets or special tokens as placeholders. Also, mention that this helps in training or fine-tuning models with structured data.
I think that's a solid approach. Let me structure it step by step to make it clear.
</think>
Chat templating is a way to structure conversation data (e.g., user/assistant interactions) into a format that language models understand. This is especially important for models trained to handle multi-turn dialogues, where the input must explicitly separate roles (user, assistant, system, etc.) and messages. Lets break this down with an example!
---
### **Step 1: Raw Conversation History**
Suppose we have this conversation:
- **User**: "Hello, how are you?"
- **Assistant**: "I'm doing great. How can I help you today?"
- **User**: "I'd like to show off how chat templating works!"
---
### **Step 2: Structured Messages**
In frameworks like Hugging Face Transformers or OpenAI, conversations are often formatted as a list of dictionaries with `role` and `content`:
```python
messages = [
{"role": "user", "content": "Hello, how are you?"},
{"role": "assistant", "content": "I'm doing great. How can I help you today?"},
{"role": "user", "content": "I'd like to show off how chat templating works!"},
]
```
---
### **Step 3: Apply a Chat Template**
A **chat template** converts this structured data into a single string formatted for the model. For example, using a Jinja-style template (common in Hugging Face):
```jinja
{% for message in messages %}
{% if message['role'] == 'user' %}
<|user|>{{ message['content'] }}<|end|>
{% elif message['role'] == 'assistant' %}
<|assistant|>{{ message['content'] }}<|end|>
{% endif %}
{% endfor %}
<|assistant|>
```
---
### **Step 4: Final Templated Output**
Applying the template to our `messages` list would produce:
```text
<|user|>Hello, how are you?<|end|>
<|assistant|>I'm doing great. How can I help you today?<|end|>
<|user|>I'd like to show off how chat templating works!<|end|>
<|assistant|>
```
This tells the model:
1. The conversation history (user/assistant turns).
2. The models turn to generate a response (`<|assistant|>` at the end).
---
### **Key Notes**:
- **Role Separation**: Tags like `<|user|>` and `<|assistant|>` help the model distinguish speakers.
- **Special Tokens**: Models often use unique tokens (e.g., `<|end|>`) to mark message boundaries.
- **Flexibility**: Templates vary by model (e.g., OpenAI uses `{"role": "user", "content": "..."}` instead of tags).
---
### **Why This Matters**:
- **Consistency**: Ensures the model understands dialogue structure.
- **Context Preservation**: Maintains the flow of multi-turn conversations.
- **Alignment**: Matches the format the model was trained on for better performance.
Want to dive deeper or see a specific frameworks implementation (e.g., OpenAI, Llama, Mistral)? Let me know! 😊<end▁of▁sentence>

## Overview
# Depth Anything
The Depth Anything model was proposed in [Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data](https://arxiv.org/abs/2401.10891) by Lihe Yang, Bingyi Kang, Zilong Huang, Xiaogang Xu, Jiashi Feng, Hengshuang Zhao. Depth Anything is based on the [DPT](dpt) architecture, trained on ~62 million images, obtaining state-of-the-art results for both relative and absolute depth estimation.
[Depth Anything](https://huggingface.co/papers/2401.10891) is designed to be a foundation model for monocular depth estimation (MDE). It is jointly trained on labeled and ~62M unlabeled images to enhance the dataset. It uses a pretrained [DINOv2](./dinov2) model as an image encoder to inherit its existing rich semantic priors, and [DPT](./dpt) as the decoder. A teacher model is trained on unlabeled images to create pseudo-labels. The student model is trained on a combination of the pseudo-labels and labeled images. To improve the student model's performance, strong perturbations are added to the unlabeled images to challenge the student model to learn more visual knowledge from the image.
<Tip>
You can find all the original Depth Anything checkpoints under the [Depth Anything](https://huggingface.co/collections/LiheYoung/depth-anything-release-65b317de04eec72abf6b55aa) collection.
[Depth Anything V2](depth_anything_v2) was released in June 2024. It uses the same architecture as Depth Anything and therefore it is compatible with all code examples and existing workflows. However, it leverages synthetic data and a larger capacity teacher model to achieve much finer and robust depth predictions.

The example below demonstrates how to obtain a depth map with [`Pipeline`] or the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*This work presents Depth Anything, a highly practical solution for robust monocular depth estimation. Without pursuing novel technical modules, we aim to build a simple yet powerful foundation model dealing with any images under any circumstances. To this end, we scale up the dataset by designing a data engine to collect and automatically annotate large-scale unlabeled data (~62M), which significantly enlarges the data coverage and thus is able to reduce the generalization error. We investigate two simple yet effective strategies that make data scaling-up promising. First, a more challenging optimization target is created by leveraging data augmentation tools. It compels the model to actively seek extra visual knowledge and acquire robust representations. Second, an auxiliary supervision is developed to enforce the model to inherit rich semantic priors from pre-trained encoders. We evaluate its zero-shot capabilities extensively, including six public datasets and randomly captured photos. It demonstrates impressive generalization ability. Further, through fine-tuning it with metric depth information from NYUv2 and KITTI, new SOTAs are set. Our better depth model also results in a better depth-conditioned ControlNet.*

<small> Depth Anything overview. Taken from the <a href="https://arxiv.org/abs/2401.10891">original paper</a>.</small>
This model was contributed by [nielsr](https://huggingface.co/nielsr).
The original code can be found [here](https://github.com/LiheYoung/Depth-Anything).
## Usage example
There are 2 main ways to use Depth Anything: either using the pipeline API, which abstracts away all the complexity for you, or by using the `DepthAnythingForDepthEstimation` class yourself.
### Pipeline API
The pipeline allows to use the model in a few lines of code:
```python
>>> from transformers import pipeline
>>> from PIL import Image
>>> import requests
>>> # load pipe
>>> pipe = pipeline(task="depth-estimation", model="LiheYoung/depth-anything-small-hf")
>>> # load image
>>> url = 'http://images.cocodataset.org/val2017/000000039769.jpg'
>>> image = Image.open(requests.get(url, stream=True).raw)
>>> # inference
>>> depth = pipe(image)["depth"]
pipe = pipeline(task="depth-estimation", model="LiheYoung/depth-anything-base-hf", torch_dtype=torch.bfloat16, device=0)
pipe("http://images.cocodataset.org/val2017/000000039769.jpg")["depth"]
```
### Using the model yourself
</hfoption>
<hfoption id="AutoModel">
If you want to do the pre- and postprocessing yourself, here's how to do that:
```py
import torch
import requests
import numpy as np
from PIL import Image
from transformers import AutoImageProcessor, AutoModelForDepthEstimation
```python
>>> from transformers import AutoImageProcessor, AutoModelForDepthEstimation
>>> import torch
>>> import numpy as np
>>> from PIL import Image
>>> import requests
image_processor = AutoImageProcessor.from_pretrained("LiheYoung/depth-anything-base-hf")
model = AutoModelForDepthEstimation.from_pretrained("LiheYoung/depth-anything-base-hf", torch_dtype=torch.bfloat16)
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = image_processor(images=image, return_tensors="pt")
>>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
>>> image = Image.open(requests.get(url, stream=True).raw)
with torch.no_grad():
outputs = model(**inputs)
>>> image_processor = AutoImageProcessor.from_pretrained("LiheYoung/depth-anything-small-hf")
>>> model = AutoModelForDepthEstimation.from_pretrained("LiheYoung/depth-anything-small-hf")
>>> # prepare image for the model
>>> inputs = image_processor(images=image, return_tensors="pt")
>>> with torch.no_grad():
... outputs = model(**inputs)
>>> # interpolate to original size and visualize the prediction
>>> post_processed_output = image_processor.post_process_depth_estimation(
... outputs,
... target_sizes=[(image.height, image.width)],
... )
>>> predicted_depth = post_processed_output[0]["predicted_depth"]
>>> depth = (predicted_depth - predicted_depth.min()) / (predicted_depth.max() - predicted_depth.min())
>>> depth = depth.detach().cpu().numpy() * 255
>>> depth = Image.fromarray(depth.astype("uint8"))
post_processed_output = image_processor.post_process_depth_estimation(
outputs,
target_sizes=[(image.height, image.width)],
)
predicted_depth = post_processed_output[0]["predicted_depth"]
depth = (predicted_depth - predicted_depth.min()) / (predicted_depth.max() - predicted_depth.min())
depth = depth.detach().cpu().numpy() * 255
Image.fromarray(depth.astype("uint8"))
```

## Overview
# DistilBERT
The DistilBERT model was proposed in the blog post [Smaller, faster, cheaper, lighter: Introducing DistilBERT, a
distilled version of BERT](https://medium.com/huggingface/distilbert-8cf3380435b5), and the paper [DistilBERT, a
distilled version of BERT: smaller, faster, cheaper and lighter](https://arxiv.org/abs/1910.01108). DistilBERT is a
small, fast, cheap and light Transformer model trained by distilling BERT base. It has 40% less parameters than
*google-bert/bert-base-uncased*, runs 60% faster while preserving over 95% of BERT's performances as measured on the GLUE language
understanding benchmark.
[DistilBERT](https://huggingface.co/papers/1910.01108) is pretrained by knowledge distillation to create a smaller model with faster inference and requires less compute to train. Through a triple loss objective during pretraining, language modeling loss, distillation loss, cosine-distance loss, DistilBERT demonstrates similar performance to a larger transformer language model.
The abstract from the paper is the following:
You can find all the original DistilBERT checkpoints under the [DistilBERT](https://huggingface.co/distilbert) organization.
*As Transfer Learning from large-scale pre-trained models becomes more prevalent in Natural Language Processing (NLP),
operating these large models in on-the-edge and/or under constrained computational training or inference budgets
remains challenging. In this work, we propose a method to pre-train a smaller general-purpose language representation
model, called DistilBERT, which can then be fine-tuned with good performances on a wide range of tasks like its larger
counterparts. While most prior work investigated the use of distillation for building task-specific models, we leverage
knowledge distillation during the pretraining phase and show that it is possible to reduce the size of a BERT model by
40%, while retaining 97% of its language understanding capabilities and being 60% faster. To leverage the inductive
biases learned by larger models during pretraining, we introduce a triple loss combining language modeling,
distillation and cosine-distance losses. Our smaller, faster and lighter model is cheaper to pre-train and we
demonstrate its capabilities for on-device computations in a proof-of-concept experiment and a comparative on-device
study.*

This model was contributed by [victorsanh](https://huggingface.co/victorsanh). This model jax version was
contributed by [kamalkraj](https://huggingface.co/kamalkraj). The original code can be found [here](https://github.com/huggingface/transformers-research-projects/tree/main/distillation).
The example below demonstrates how to classify text with [`Pipeline`], [`AutoModel`], and from the command line.
## Usage tips
<hfoptions id="usage">
<hfoption id="Pipeline">
```py
from transformers import pipeline
classifier = pipeline(
task="text-classification",
model="distilbert-base-uncased-finetuned-sst-2-english",
torch_dtype=torch.float16,
device=0
)
result = classifier("I love using Hugging Face Transformers!")
print(result)
# Output: [{'label': 'POSITIVE', 'score': 0.9998}]
```
</hfoption>
<hfoption id="AutoModel">
```py
import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(
"distilbert/distilbert-base-uncased-finetuned-sst-2-english",
)
model = AutoModelForSequenceClassification.from_pretrained(
"distilbert/distilbert-base-uncased-finetuned-sst-2-english",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
inputs = tokenizer("I love using Hugging Face Transformers!", return_tensors="pt").to("cuda")
with torch.no_grad():
outputs = model(**inputs)
predicted_class_id = torch.argmax(outputs.logits, dim=-1).item()
predicted_label = model.config.id2label[predicted_class_id]
print(f"Predicted label: {predicted_label}")
```
</hfoption>
<hfoption id="transformers-cli">
```bash
echo -e "I love using Hugging Face Transformers!" | transformers-cli run --task text-classification --model distilbert-base-uncased-finetuned-sst-2-english
```
</hfoption>
</hfoptions>
## Notes
- DistilBERT doesn't have `token_type_ids`, you don't need to indicate which token belongs to which segment. Just
separate your segments with the separation token `tokenizer.sep_token` (or `[SEP]`).
- DistilBERT doesn't have options to select the input positions (`position_ids` input). This could be added if
necessary though, just let us know if you need this option.
- Same as BERT but smaller. Trained by distillation of the pretrained BERT model, meaning its been trained to predict the same probabilities as the larger model. The actual objective is a combination of:
* finding the same probabilities as the teacher model
* predicting the masked tokens correctly (but no next-sentence objective)
* a cosine similarity between the hidden states of the student and the teacher model
### 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.
```
from transformers import DistilBertModel
model = DistilBertModel.from_pretrained("distilbert-base-uncased", 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 (NVIDIA GeForce RTX 2060-8GB, PyTorch 2.3.1, OS Ubuntu 20.04) with `float16` and the `distilbert-base-uncased` model with
a MaskedLM head, we saw the following speedups during training and inference.

## Combining DistilBERT 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 AutoTokenizer, AutoModel
>>> device = "cuda" # the device to load the model onto
>>> tokenizer = AutoTokenizer.from_pretrained('distilbert/distilbert-base-uncased')
>>> model = AutoModel.from_pretrained("distilbert/distilbert-base-uncased", torch_dtype=torch.float16, attn_implementation="flash_attention_2")
>>> text = "Replace me by any text you'd like."
>>> encoded_input = tokenizer(text, return_tensors='pt').to(device)
>>> model.to(device)
>>> output = model(**encoded_input)
```

## Overview
# ELECTRA
The ELECTRA model was proposed in the paper [ELECTRA: Pre-training Text Encoders as Discriminators Rather Than
Generators](https://openreview.net/pdf?id=r1xMH1BtvB). ELECTRA is a new pretraining approach which trains two
transformer models: the generator and the discriminator. The generator's role is to replace tokens in a sequence, and
is therefore trained as a masked language model. The discriminator, which is the model we're interested in, tries to
identify which tokens were replaced by the generator in the sequence.
[ELECTRA](https://huggingface.co/papers/2003.10555) modifies the pretraining objective of traditional masked language models like BERT. Instead of just masking tokens and asking the model to predict them, ELECTRA trains two models, a generator and a discriminator. The generator replaces some tokens with plausible alternatives and the discriminator (the model you'll actually use) learns to detect which tokens are original and which were replaced. This training approach is very efficient and scales to larger models while using considerably less compute.
The abstract from the paper is the following:
This approach is super efficient because ELECTRA learns from every single token in the input, not just the masked ones. That's why even the small ELECTRA models can match or outperform much larger models while using way less computing resources.
*Masked language modeling (MLM) pretraining methods such as BERT corrupt the input by replacing some tokens with [MASK]
and then train a model to reconstruct the original tokens. While they produce good results when transferred to
downstream NLP tasks, they generally require large amounts of compute to be effective. As an alternative, we propose a
more sample-efficient pretraining task called replaced token detection. Instead of masking the input, our approach
corrupts it by replacing some tokens with plausible alternatives sampled from a small generator network. Then, instead
of training a model that predicts the original identities of the corrupted tokens, we train a discriminative model that
predicts whether each token in the corrupted input was replaced by a generator sample or not. Thorough experiments
demonstrate this new pretraining task is more efficient than MLM because the task is defined over all input tokens
rather than just the small subset that was masked out. As a result, the contextual representations learned by our
approach substantially outperform the ones learned by BERT given the same model size, data, and compute. The gains are
particularly strong for small models; for example, we train a model on one GPU for 4 days that outperforms GPT (trained
using 30x more compute) on the GLUE natural language understanding benchmark. Our approach also works well at scale,
where it performs comparably to RoBERTa and XLNet while using less than 1/4 of their compute and outperforms them when
using the same amount of compute.*

## Usage tips
The example below demonstrates how to classify text with [`Pipeline`] or the [`AutoModel`] class.
- ELECTRA is the pretraining approach, therefore there is nearly no changes done to the underlying model: BERT. The
only change is the separation of the embedding size and the hidden size: the embedding size is generally smaller,
while the hidden size is larger. An additional projection layer (linear) is used to project the embeddings from their
embedding size to the hidden size. In the case where the embedding size is the same as the hidden size, no projection
layer is used.
- ELECTRA is a transformer model pretrained with the use of another (small) masked language model. The inputs are corrupted by that language model, which takes an input text that is randomly masked and outputs a text in which ELECTRA has to predict which token is an original and which one has been replaced. Like for GAN training, the small language model is trained for a few steps (but with the original texts as objective, not to fool the ELECTRA model like in a traditional GAN setting) then the ELECTRA model is trained for a few steps.
- The ELECTRA checkpoints saved using [Google Research's implementation](https://github.com/google-research/electra)
contain both the generator and discriminator. The conversion script requires the user to name which model to export
into the correct architecture. Once converted to the HuggingFace format, these checkpoints may be loaded into all
available ELECTRA models, however. This means that the discriminator may be loaded in the
[`ElectraForMaskedLM`] model, and the generator may be loaded in the
[`ElectraForPreTraining`] model (the classification head will be randomly initialized as it
doesn't exist in the generator).

## Notes
- ELECTRA consists of two transformer models, a generator (G) and a discriminator (D). For most downstream tasks, use the discriminator model (as indicated by `*-discriminator` in the name) rather than the generator.
- ELECTRA comes in three sizes: small (14M parameters), base (110M parameters), and large (335M parameters).
- ELECTRA can use a smaller embedding size than the hidden size for efficiency. When `embedding_size` is smaller than `hidden_size` in the configuration, a projection layer connects them.
- When using batched inputs with padding, make sure to use attention masks to prevent the model from attending to padding tokens.
```py
# Example of properly handling padding with attention masks
inputs = tokenizer(["Short text", "This is a much longer text that needs padding"],
padding=True,
return_tensors="pt")
outputs = model(**inputs) # automatically uses the attention_mask
```
- When using the discriminator for a downstream task, you can load it into any of the ELECTRA model classes ([`ElectraForSequenceClassification`], [`ElectraForTokenClassification`], etc.).

## Overview
# Falcon
Falcon is a class of causal decoder-only models built by [TII](https://www.tii.ae/). The largest Falcon checkpoints
have been trained on >=1T tokens of text, with a particular emphasis on the [RefinedWeb](https://arxiv.org/abs/2306.01116)
corpus. They are made available under the Apache 2.0 license.
[Falcon](https://huggingface.co/papers/2311.16867) is a family of large language models, available in 7B, 40B, and 180B parameters, as pretrained and instruction tuned variants. This model focuses on scaling pretraining over three categories, performance, data, and hardware. Falcon uses multigroup attention to significantly reduce inference memory requirements and rotary positional embeddings (RoPE). These models are pretrained on [RefinedWeb](https://huggingface.co/datasets/tiiuae/falcon-refinedweb), a high-quality and deduplicated 5T token dataset.
You can find all the original Falcon checkpoints under the [Falcon](https://huggingface.co/collections/tiiuae/falcon-64fb432660017eeec9837b5a) collection.
Falcon's architecture is modern and optimized for inference, with multi-query attention and support for efficient
attention variants like `FlashAttention`. Both 'base' models trained only as causal language models as well as
'instruct' models that have received further fine-tuning are available.
> [!TIP]
> Click on the Falcon models in the right sidebar for more examples of how to apply Falcon to different language tasks.
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line.
Falcon models are (as of 2023) some of the largest and most powerful open-source language models,
and consistently rank highly in the [OpenLLM leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard).

<hfoption id="Pipeline">
## Converting custom checkpoints
```py
import torch
from transformers import pipeline
<Tip>
pipeline = pipeline(
task="text-generation",
model="tiiuae/falcon-7b-instruct",
torch_dtype=torch.bfloat16,
device=0
)
pipeline(
"Write a short poem about coding",
max_length=100,
do_sample=True,
temperature=0.7
)
```
Falcon models were initially added to the Hugging Face Hub as custom code checkpoints. However, Falcon is now fully
supported in the Transformers library. If you fine-tuned a model from a custom code checkpoint, we recommend converting
your checkpoint to the new in-library format, as this should give significant improvements to stability and
performance, especially for generation, as well as removing the need to use `trust_remote_code=True`!
</hfoption>
<hfoption id="AutoModel">
</Tip>
```py
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
You can convert custom code checkpoints to full Transformers checkpoints using the `convert_custom_code_checkpoint.py`
script located in the
[Falcon model directory](https://github.com/huggingface/transformers/tree/main/src/transformers/models/falcon)
of the Transformers library. To use this script, simply call it with
`python convert_custom_code_checkpoint.py --checkpoint_dir my_model`. This will convert your checkpoint in-place, and
you can immediately load it from the directory afterwards with e.g. `from_pretrained()`. If your model hasn't been
uploaded to the Hub, we recommend making a backup before attempting the conversion, just in case!
tokenizer = AutoTokenizer.from_pretrained("tiiuae/falcon-7b-instruct")
model = AutoModelForCausalLM.from_pretrained(
"tiiuae/falcon-7b-instruct",
torch_dtype=torch.bfloat16,
device_map="auto",
attn_implementation="sdpa",
)
input_ids = tokenizer("Write a short poem about coding", return_tensors="pt").to("cuda")
output = model.generate(**input_ids)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
</hfoption>

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 4-bits.
```python
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_compute_dtype=torch.bfloat16,
bnb_4bit_quant_type="nf4",
bnb_4bit_use_double_quant=True,
)
tokenizer = AutoTokenizer.from_pretrained("tiiuae/falcon-7b")
model = AutoModelForCausalLM.from_pretrained(
"tiiuae/falcon-7b",
torch_dtype=torch.bfloat16,
device_map="auto",
quantization_config=quantization_config,
)
inputs = tokenizer("In quantum physics, entanglement means", return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
## Notes
- If you're upgrading from an older custom code checkpoint, remember to convert it to the official Transformers format for better stability and performance using the conversion script located in the [Falcon model directory](https://github.com/huggingface/transformers/tree/main/src/transformers/models/falcon).
```bash
python convert_custom_code_checkpoint.py --checkpoint_dir my_model

Llama 4, developed by Meta, introduces a new auto-regressive Mixture-of-Experts (MoE) architecture.
This generation includes two models:
- The highly capable Llama 4 Maverick with 17B active parameters out of ~400B total, with 128 experts.
- The efficient Llama 4 Scout also has 17B active parameters out of ~109B total, using just 16 experts.
-
Both models leverage early fusion for native multimodality, enabling them to process text and image inputs.
Maverick and Scout are both trained on up to 40 trillion tokens on data encompassing 200 languages
(with specific fine-tuning support for 12 languages including Arabic, Spanish, German, and Hindi).
For deployment, Llama 4 Scout is designed for accessibility, fitting on a single server-grade GPU via
on-the-fly 4-bit or 8-bitint4 quantization, while Maverick is available in BF16 and FP8 formats.
These models are released under the custom Llama 4 Community License Agreement, available on the model repositories.
You can find all the original Llama checkpoints under the [meta-llama](https://huggingface.co/meta-llama) organization.
> [!TIP]
> The Llama 4 family of models comes in two flavors: 109B, and 402B parameters. Both of these flavors are extremely
> large and won't fit on your run-of-the-mill device. See below for some examples to reduce the memory usage of the
> model.
>
> For the download to be faster and more resilient, we recommend installing the `hf_xet` dependency as followed:
> `pip install transformers[hf_xet]`
The examples below demonstrates how to generate with [`Pipeline`] or the [`AutoModel`]. We additionally add an example
showcasing how to toggle the right attributes to enable very long-context generations, as some flavors of Llama 4
have context lengths going up to 10 million tokens.

## Efficiency; how to get the best out of llama 4
### The Attention methods
Updating the default attention function can significantly improve compute performance as well as memory usage. Refer to the [Attention Interface](../attention_interface) overview for an in-depth explanation of our interface.
As of release, the Llama 4 model supports the following attention methods: `eager`, `flex_attention`, `sdpa`. We recommend using `flex_attention` for best results.
Switching attention mechanism is done at the model initialization step:
<hfoptions id="Attention">
<hfoption id="Flex Attention">
Setting Flex Attention ensures the best results with the very long context the model can handle.
> [!TIP] Beware: the example below uses both `device_map="auto"` and flex-attention.
> Please use `torchrun` to run this example in tensor-parallel mode.
>
> We will work to enable running with `device_map="auto"` and flex-attention without
> tensor-parallel in the future.
```py
from transformers import Llama4ForConditionalGeneration
import torch
model = Llama4ForConditionalGeneration.from_pretrained(
model_id,
attn_implementation="flex_attention",
device_map="auto",
torch_dtype=torch.bfloat16,
)
```
</hfoption>
<hfoption id="SDPA">
The `sdpa` attention method is generally more compute-efficient than the `eager` method.
```py
from transformers import Llama4ForConditionalGeneration
import torch
model = Llama4ForConditionalGeneration.from_pretrained(
model_id,
attn_implementation="sdpa",
device_map="auto",
torch_dtype=torch.bfloat16,
)
```
</hfoption>
<hfoption id="Eager">
The `eager` attention method is set by default, so no need for anything different when loading the model:
```py
from transformers import Llama4ForConditionalGeneration
import torch
model = Llama4ForConditionalGeneration.from_pretrained(
model_id,
device_map="auto",
torch_dtype=torch.bfloat16,
)
```
</hfoption>
</hfoptions>
### Quantization
Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for available quantization backends.
At time of release, both FBGEMM and LLM-Compressor are supported; more quantization methods will be supported in the days that follow the release.
See below for examples using both:
Here is an example loading an BF16 model in FP8 using the FBGEMM approach:
<hfoptions id="Quantization">
<hfoption id="FBGEMM">
```python
from transformers import AutoTokenizer, Llama4ForConditionalGeneration, FbgemmFp8Config
import torch
model_id = "meta-llama/Llama-4-Scout-17B-16E-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
messages = [
{"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt", return_dict=True)
model = Llama4ForConditionalGeneration.from_pretrained(
model_id,
device_map="auto",
torch_dtype=torch.bfloat16,
quantization_config=FbgemmFp8Config()
)
outputs = model.generate(**inputs.to(model.device), max_new_tokens=100)
outputs = tokenizer.batch_decode(outputs[:, inputs["input_ids"].shape[-1]:])
print(outputs[0])
```
</hfoption>
<hfoption id="LLM-Compressor">
To use the LLM-Compressor technique, we recommend leveraging the pre-quantized FP8 checkpoint available with the release:
```python
from transformers import AutoTokenizer, Llama4ForConditionalGeneration
import torch
model_id = "meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8"
tokenizer = AutoTokenizer.from_pretrained(model_id)
messages = [
{"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt", return_dict=True)
model = Llama4ForConditionalGeneration.from_pretrained(
model_id,
tp_plan="auto",
torch_dtype=torch.bfloat16,
)
outputs = model.generate(**inputs.to(model.device), max_new_tokens=100)
outputs = tokenizer.batch_decode(outputs[:, inputs["input_ids"].shape[-1]:])
print(outputs[0])
```
</hfoption>
</hfoptions>
### Offloading
Enabling CPU-offloading means that components of the model might be moved to CPU instead of GPU in case the GPU-memory available isn't sufficient to load the entire model.
At inference, different components will be loaded/unloaded from/to the GPU on the fly. This ensures that the model can be loaded on smaller machines as long as the CPU-memory is sufficient.
However, this also slows down inference as it adds communication overhead.
In order to enable CPU-offloading, you simply need to specify the `device_map` to `auto` at model load:
```py

## Overview
# MobileBERT
The MobileBERT model was proposed in [MobileBERT: a Compact Task-Agnostic BERT for Resource-Limited Devices](https://arxiv.org/abs/2004.02984) by Zhiqing Sun, Hongkun Yu, Xiaodan Song, Renjie Liu, Yiming Yang, and Denny
Zhou. It's a bidirectional transformer based on the BERT model, which is compressed and accelerated using several
approaches.
[MobileBERT](https://huggingface.co/papers/2004.02984) is a lightweight and efficient variant of BERT, specifically designed for resource-limited devices such as mobile phones. It retains BERT's architecture but significantly reduces model size and inference latency while maintaining strong performance on NLP tasks. MobileBERT achieves this through a bottleneck structure and carefully balanced self-attention and feedforward networks. The model is trained by knowledge transfer from a large BERT model with an inverted bottleneck structure.
The abstract from the paper is the following:
You can find the original MobileBERT checkpoint under the [Google](https://huggingface.co/google/mobilebert-uncased) organization.

*Natural Language Processing (NLP) has recently achieved great success by using huge pre-trained models with hundreds
of millions of parameters. However, these models suffer from heavy model sizes and high latency such that they cannot
be deployed to resource-limited mobile devices. In this paper, we propose MobileBERT for compressing and accelerating
the popular BERT model. Like the original BERT, MobileBERT is task-agnostic, that is, it can be generically applied to
various downstream NLP tasks via simple fine-tuning. Basically, MobileBERT is a thin version of BERT_LARGE, while
equipped with bottleneck structures and a carefully designed balance between self-attentions and feed-forward networks.
To train MobileBERT, we first train a specially designed teacher model, an inverted-bottleneck incorporated BERT_LARGE
model. Then, we conduct knowledge transfer from this teacher to MobileBERT. Empirical studies show that MobileBERT is
4.3x smaller and 5.5x faster than BERT_BASE while achieving competitive results on well-known benchmarks. On the
natural language inference tasks of GLUE, MobileBERT achieves a GLUEscore o 77.7 (0.6 lower than BERT_BASE), and 62 ms
latency on a Pixel 4 phone. On the SQuAD v1.1/v2.0 question answering task, MobileBERT achieves a dev F1 score of
90.0/79.2 (1.5/2.1 higher than BERT_BASE).*
The example below demonstrates how to predict the `[MASK]` token with [`Pipeline`], [`AutoModel`], and from the command line.
This model was contributed by [vshampor](https://huggingface.co/vshampor). The original code can be found [here](https://github.com/google-research/google-research/tree/master/mobilebert).

## Usage tips
```py
import torch
from transformers import pipeline
- MobileBERT is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather
than the left.
- MobileBERT is similar to BERT and therefore relies on the masked language modeling (MLM) objective. It is therefore
efficient at predicting masked tokens and at NLU in general, but is not optimal for text generation. Models trained
with a causal language modeling (CLM) objective are better in that regard.

## Overview
# ModernBERT
The ModernBERT model was proposed in [Smarter, Better, Faster, Longer: A Modern Bidirectional Encoder for Fast, Memory Efficient, and Long Context Finetuning and Inference](https://arxiv.org/abs/2412.13663) by Benjamin Warner, Antoine Chaffin, Benjamin Clavié, Orion Weller, Oskar Hallström, Said Taghadouini, Alexis Galalgher, Raja Bisas, Faisal Ladhak, Tom Aarsen, Nathan Cooper, Grifin Adams, Jeremy Howard and Iacopo Poli.
[ModernBERT](https://huggingface.co/papers/2412.13663) is a modernized version of [`BERT`] trained on 2T tokens. It brings many improvements to the original architecture such as rotary positional embeddings to support sequences of up to 8192 tokens, unpadding to avoid wasting compute on padding tokens, GeGLU layers, and alternating attention.
It is a refresh of the traditional encoder architecture, as used in previous models such as [BERT](https://huggingface.co/docs/transformers/en/model_doc/bert) and [RoBERTa](https://huggingface.co/docs/transformers/en/model_doc/roberta).
You can find all the original ModernBERT checkpoints under the [ModernBERT](https://huggingface.co/collections/answerdotai/modernbert-67627ad707a4acbf33c41deb) collection.
It builds on BERT and implements many modern architectural improvements which have been developed since its original release, such as:
- [Rotary Positional Embeddings](https://huggingface.co/blog/designing-positional-encoding) to support sequences of up to 8192 tokens.
- [Unpadding](https://arxiv.org/abs/2208.08124) to ensure no compute is wasted on padding tokens, speeding up processing time for batches with mixed-length sequences.
- [GeGLU](https://arxiv.org/abs/2002.05202) Replacing the original MLP layers with GeGLU layers, shown to improve performance.
- [Alternating Attention](https://arxiv.org/abs/2004.05150v2) where most attention layers employ a sliding window of 128 tokens, with Global Attention only used every 3 layers.
- [Flash Attention](https://github.com/Dao-AILab/flash-attention) to speed up processing.
- A model designed following recent [The Case for Co-Designing Model Architectures with Hardware](https://arxiv.org/abs/2401.14489), ensuring maximum efficiency across inference GPUs.
- Modern training data scales (2 trillion tokens) and mixtures (including code ande math data)

The abstract from the paper is the following:
The example below demonstrates how to predict the `[MASK]` token with [`Pipeline`], [`AutoModel`], and from the command line.
*Encoder-only transformer models such as BERT offer a great performance-size tradeoff for retrieval and classification tasks with respect to larger decoder-only models. Despite being the workhorse of numerous production pipelines, there have been limited Pareto improvements to BERT since its release. In this paper, we introduce ModernBERT, bringing modern model optimizations to encoder-only models and representing a major Pareto improvement over older encoders. Trained on 2 trillion tokens with a native 8192 sequence length, ModernBERT models exhibit state-of-the-art results on a large pool of evaluations encompassing diverse classification tasks and both single and multi-vector retrieval on different domains (including code). In addition to strong downstream performance, ModernBERT is also the most speed and memory efficient encoder and is designed for inference on common GPUs.*

## Overview
OpenAI GPT model was proposed in [Improving Language Understanding by Generative Pre-Training](https://s3-us-west-2.amazonaws.com/openai-assets/research-covers/language-unsupervised/language_understanding_paper.pdf)
by Alec Radford, Karthik Narasimhan, Tim Salimans and Ilya Sutskever. It's a causal (unidirectional) transformer
pre-trained using language modeling on a large corpus with long range dependencies, the Toronto Book Corpus.
The abstract from the paper is the following:
*Natural language understanding comprises a wide range of diverse tasks such as textual entailment, question answering,
semantic similarity assessment, and document classification. Although large unlabeled text corpora are abundant,
labeled data for learning these specific tasks is scarce, making it challenging for discriminatively trained models to
perform adequately. We demonstrate that large gains on these tasks can be realized by generative pretraining of a
language model on a diverse corpus of unlabeled text, followed by discriminative fine-tuning on each specific task. In
contrast to previous approaches, we make use of task-aware input transformations during fine-tuning to achieve
effective transfer while requiring minimal changes to the model architecture. We demonstrate the effectiveness of our
approach on a wide range of benchmarks for natural language understanding. Our general task-agnostic model outperforms
discriminatively trained models that use architectures specifically crafted for each task, significantly improving upon
the state of the art in 9 out of the 12 tasks studied.*
[Write With Transformer](https://transformer.huggingface.co/doc/gpt) is a webapp created and hosted by Hugging Face
showcasing the generative capabilities of several models. GPT is one of them.
This model was contributed by [thomwolf](https://huggingface.co/thomwolf). The original code can be found [here](https://github.com/openai/finetune-transformer-lm).
## Usage tips
- GPT is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.
- GPT was trained with a causal language modeling (CLM) objective and is therefore powerful at predicting the next
token in a sequence. Leveraging this feature allows GPT-2 to generate syntactically coherent text as it can be
observed in the *run_generation.py* example script.
Note:
# GPT
If you want to reproduce the original tokenization process of the *OpenAI GPT* paper, you will need to install `ftfy`
and `SpaCy`:
[GPT (Generative Pre-trained Transformer)](https://cdn.openai.com/research-covers/language-unsupervised/language_understanding_paper.pdf) focuses on effectively learning text representations and transferring them to tasks. This model trains the Transformer decoder to predict the next word, and then fine-tuned on labeled data.
```bash
pip install spacy ftfy==4.4.3
python -m spacy download en
GPT can generate high-quality text, making it well-suited for a variety of natural language understanding tasks such as textual entailment, question answering, semantic similarity, and document classification.
You can find all the original GPT checkpoints under the [OpenAI community](https://huggingface.co/openai-community/openai-gpt) organization.

output = generator("The future of AI is", max_length=50, do_sample=True)
print(output[0]["generated_text"])
```
If you don't install `ftfy` and `SpaCy`, the [`OpenAIGPTTokenizer`] will default to tokenize
using BERT's `BasicTokenizer` followed by Byte-Pair Encoding (which should be fine for most usage, don't worry).

# Phi4 Multimodal
## Overview
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:
- Text: Arabic, Chinese, Czech, Danish, Dutch, English, Finnish, French, German, Hebrew, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian
- Vision: English
- Audio: English, Chinese, German, French, Italian, Japanese, Spanish, Portuguese
This model was contributed by [Cyril Vallez](https://huggingface.co/cyrilvallez). The most recent code can be
found [here](https://github.com/huggingface/transformers/blob/main/src/transformers/models/phi4_multimodal/modeling_phi4_multimodal.py).
## Usage tips
`Phi4-multimodal-instruct` can be found on the [Huggingface Hub](https://huggingface.co/microsoft/Phi-4-multimodal-instruct)

## Overview
# Qwen2
Qwen2 is the new model series of large language models from the Qwen team. Previously, we released the Qwen series, including Qwen2-0.5B, Qwen2-1.5B, Qwen2-7B, Qwen2-57B-A14B, Qwen2-72B, Qwen2-Audio, etc.
[Qwen2](https://huggingface.co/papers/2407.10671) is a family of large language models (pretrained, instruction-tuned and mixture-of-experts) available in sizes from 0.5B to 72B parameters. The models are built on the Transformer architecture featuring enhancements like group query attention (GQA), rotary positional embeddings (RoPE), a mix of sliding window and full attention, and dual chunk attention with YARN for training stability. Qwen2 models support multiple languages and context lengths up to 131,072 tokens.
### Model Details
You can find all the official Qwen2 checkpoints under the [Qwen2](https://huggingface.co/collections/Qwen/qwen2-6659360b33528ced941e557f) collection.
Qwen2 is a language model series including decoder language models of different model sizes. For each size, we release the base language model and the aligned chat model. It is based on the Transformer architecture with SwiGLU activation, attention QKV bias, group query attention, mixture of sliding window attention and full attention, etc. Additionally, we have an improved tokenizer adaptive to multiple natural languages and codes.
> [!TIP]
> Click on the Qwen2 models in the right sidebar for more examples of how to apply Qwen2 to different language tasks.
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line using the instruction-tuned models.
## Usage tips
`Qwen2-7B` and `Qwen2-7B-Instruct` can be found on the [Huggingface Hub](https://huggingface.co/Qwen)
In the following, we demonstrate how to use `Qwen2-7B-Instruct` for the inference. Note that we have used the ChatML format for dialog, in this demo we show how to leverage `apply_chat_template` for this purpose.

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 4-bits.
```python
# pip install -U flash-attn --no-build-isolation
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(

outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

## Overview
# Qwen2.5-VL
The [Qwen2.5-VL](https://qwenlm.github.io/blog/qwen2_5-vl/) model is an update to [Qwen2-VL](https://arxiv.org/abs/2409.12191) from Qwen team, Alibaba Group.
[Qwen2.5-VL](https://huggingface.co/papers/2502.13923) is a multimodal vision-language model, available in 3B, 7B, and 72B parameters, pretrained on 4.1T tokens. The model introduces window attention in the ViT encoder to accelerate training and inference, dynamic FPS sampling on the spatial and temporal dimensions for better video understanding across different sampling rates, and an upgraded MRoPE (multi-resolutional rotary positional encoding) mechanism to better capture and learn temporal dynamics.
The abstract from this update is the following:
*Qwen2.5-VL marks a major step forward from Qwen2-VL, built upon the latest Qwen2.5 LLM. We've accelerated training and testing through the strategic implementation of window attention within the ViT. The ViT architecture itself has been refined with SwiGLU and RMSNorm, aligning it more closely with the LLM's structure. A key innovation is the expansion of native dynamic resolution to encompass the temporal dimension, in addition to spatial aspects. Furthermore, we've upgraded MRoPE, incorporating absolute time alignment on the time axis to allow the model to effectively capture temporal dynamics, regardless of frame rate, leading to superior video understanding.*
You can find all the original Qwen2.5-VL checkpoints under the [Qwen2.5-VL](https://huggingface.co/collections/Qwen/qwen25-vl-6795ffac22b334a837c0f9a5) collection.

### Batch Mixed Media Inference
The model can batch inputs composed of mixed samples of various types such as images, videos, and text. Here is an example.
```python
# Conversation for the first image
conversation1 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image1.jpg"},
{"type": "text", "text": "Describe this image."}
]
}
]
# Conversation with two images
conversation2 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image2.jpg"},
{"type": "image", "path": "/path/to/image3.jpg"},
{"type": "text", "text": "What is written in the pictures?"}
]
}
]
# Conversation with pure text
conversation3 = [
{
"role": "user",
"content": "who are you?"
}
]
# Conversation with mixed midia
conversation4 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image3.jpg"},
{"type": "image", "path": "/path/to/image4.jpg"},
{"type": "video", "path": "/path/to/video.jpg"},
{"type": "text", "text": "What are the common elements in these medias?"},
],
}
]
conversations = [conversation1, conversation2, conversation3, conversation4]
# Preparation for batch inference
ipnuts = processor.apply_chat_template(
conversations,
video_fps=1,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device)
# Batch Inference
output_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, output_ids)]
output_text = processor.batch_decode(generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True)
print(output_text)
```
### Usage Tips
#### Image Resolution trade-off
The model supports a wide range of resolution inputs. By default, it uses the native resolution for input, but higher resolutions can enhance performance at the cost of more computation. Users can set the minimum and maximum number of pixels to achieve an optimal configuration for their needs.
```python
min_pixels = 224*224
max_pixels = 2048*2048
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```
In case of limited GPU RAM, one can reduce the resolution as follows:
```python
min_pixels = 256*28*28
max_pixels = 1024*28*28
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```
This ensures each image gets encoded using a number between 256-1024 tokens. The 28 comes from the fact that the model uses a patch size of 14 and a temporal patch size of 2 (14 x 2 = 28).
#### Multiple Image Inputs
By default, images and video content are directly included in the conversation. When handling multiple images, it's helpful to add labels to the images and videos for better reference. Users can control this behavior with the following settings:
```python
conversation = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "Hello, how are you?"}
]
},
{
"role": "assistant",
"content": "I'm doing well, thank you for asking. How can I assist you today?"
},
{

#### Flash-Attention 2 to speed up generation
First, make sure to install the latest version of Flash Attention 2:
```bash
pip install -U flash-attn --no-build-isolation
```
Also, you should have hardware that is compatible with FlashAttention 2. Read more about it in the official documentation of the [flash attention repository](https://github.com/Dao-AILab/flash-attention). FlashAttention-2 can only be used when a model is loaded in `torch.float16` or `torch.bfloat16`.
To load and run a model using FlashAttention-2, add `attn_implementation="flash_attention_2"` when loading the model:
```python
from transformers import Qwen2_5_VLForConditionalGeneration
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct",
torch_dtype=torch.bfloat16,
attn_implementation="flash_attention_2",
output_text = processor.batch_decode(
generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
```
</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 [torchao](../quantization/torchao) to only quantize the weights to int4.
```python
import torch
from transformers import TorchAoConfig, Gemma3ForConditionalGeneration, AutoProcessor
quantization_config = TorchAoConfig("int4_weight_only", group_size=128)
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct",
torch_dtype=torch.bfloat16,
device_map="auto",
quantization_config=quantization_config
)
```
### Notes
- Use Qwen2.5-VL for video inputs by setting `"type": "video"` as shown below.
```python
conversation = [
{
"role": "user",
"content": [
{"type": "video", "path": "/path/to/video.mp4"},
{"type": "text", "text": "What happened in the video?"},
],
}
]
inputs = processor.apply_chat_template(
conversation,
video_fps=1,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device)
# Inference: Generation of the output
output_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, output_ids)]
output_text = processor.batch_decode(generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True)
print(output_text)
```
- Use Qwen2.5-VL for a mixed batch of inputs (images, videos, text). Add labels when handling multiple images or videos for better reference
as show below.
```python
import torch
from transformers import Qwen2_5_VLForConditionalGeneration, AutoProcessor
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct")
conversation = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "Hello, how are you?"}
]
},
{
"role": "assistant",
"content": "I'm doing well, thank you for asking. How can I assist you today?"
},
{
"role": "user",
"content": [
{"type": "text", "text": "Can you describe these images and video?"},
{"type": "image"},
{"type": "image"},
{"type": "video"},
{"type": "text", "text": "These are from my vacation."}
]
},
{
"role": "assistant",
"content": "I'd be happy to describe the images and video for you. Could you please provide more context about your vacation?"
},
{
"role": "user",
"content": "It was a trip to the mountains. Can you see the details in the images and video?"
}
]
# default:
prompt_without_id = processor.apply_chat_template(conversation, add_generation_prompt=True)
# Excepted output: '<|im_start|>system\nYou are a helpful assistant.<|im_end|>\n<|im_start|>user\n<|vision_start|><|image_pad|><|vision_end|>Hello, how are you?<|im_end|>\n<|im_start|>assistant\nI'm doing well, thank you for asking.

Can you see the details in the images and video?<|im_end|>\n<|im_start|>assistant\n'
```
- Use the `min_pixels` and `max_pixels` parameters in [`AutoProcessor`] to set the resolution.
```python
min_pixels = 224*224
max_pixels = 2048*2048
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```
Higher resolution can require more compute whereas reducing the resolution can save memory as follows:
```python
min_pixels = 256*28*28
max_pixels = 1024*28*28
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```

## Overview
The ShieldGemma 2 model was proposed in a forthcoming technical report by Google. ShieldGemma 2 is built on [Gemma 3](https://ai.google.dev/gemma/docs/core/model_card_3), is a 4 billion (4B) parameter model that checks the safety of both synthetic and natural images against key categories to help you build robust datasets and models. With this addition to the Gemma family of models, researchers and developers can now easily minimize the risk of harmful content in their models across key areas of harm as defined below:

- No Sexually Explicit content: The image shall not contain content that depicts explicit or graphic sexual acts (e.g., pornography, erotic nudity, depictions of rape or sexual assault).
- No Dangerous Content: The image shall not contain content that facilitates or encourages activities that could cause real-world harm (e.g., building firearms and explosive devices, promotion of terrorism, instructions for suicide).

## Overview
# T5
The T5 model was presented in [Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer](https://arxiv.org/pdf/1910.10683.pdf) by [Colin Raffel](https://huggingface.co/craffel), Noam Shazeer, [Adam Roberts](https://huggingface.co/adarob), Katherine Lee, Sharan Narang,
Michael Matena, Yanqi Zhou, Wei Li, [Peter J. Liu](https://huggingface.co/peterjliu).
[T5](https://huggingface.co/papers/1910.10683) is a encoder-decoder transformer available in a range of sizes from 60M to 11B parameters. It is designed to handle a wide range of NLP tasks by treating them all as text-to-text problems. This eliminates the need for task-specific architectures because T5 converts every NLP task into a text generation task.
The abstract from the paper is the following:
To formulate every task as text generation, each task is prepended with a task-specific prefix (e.g., translate English to German: ..., summarize: ...). This enables T5 to handle tasks like translation, summarization, question answering, and more.
*Transfer learning, where a model is first pre-trained on a data-rich task before being fine-tuned on a downstream
task, has emerged as a powerful technique in natural language processing (NLP). The effectiveness of transfer learning
has given rise to a diversity of approaches, methodology, and practice. In this paper, we explore the landscape of
transfer learning techniques for NLP by introducing a unified framework that converts every language problem into a
text-to-text format. Our systematic study compares pretraining objectives, architectures, unlabeled datasets, transfer
approaches, and other factors on dozens of language understanding tasks. By combining the insights from our exploration
with scale and our new "Colossal Clean Crawled Corpus", we achieve state-of-the-art results on many benchmarks covering
summarization, question answering, text classification, and more. To facilitate future work on transfer learning for
NLP, we release our dataset, pre-trained models, and code.*

This model was contributed by [thomwolf](https://huggingface.co/thomwolf). The original code can be found [here](https://github.com/google-research/text-to-text-transfer-transformer).
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and how to translate with T5 from the command line.
## Usage tips
<hfoptions id="usage">
<hfoption id="Pipeline">
- T5 is an encoder-decoder model pre-trained on a multi-task mixture of unsupervised and supervised tasks and for which
each task is converted into a text-to-text format. T5 works well on a variety of tasks out-of-the-box by prepending a
different prefix to the input corresponding to each task, e.g., for translation: *translate English to German: ...*,
for summarization: *summarize: ...*.
- The pretraining includes both supervised and self-supervised training. Supervised training is conducted on downstream tasks provided by the GLUE and SuperGLUE benchmarks (converting them into text-to-text tasks as explained above).
- Self-supervised training uses corrupted tokens, by randomly removing 15% of the tokens and replacing them with individual sentinel tokens (if several consecutive tokens are marked for removal, the whole group is replaced with a single sentinel token). The input of the encoder is the corrupted sentence, the input of the decoder is the original sentence and the target is then the dropped out tokens delimited by their sentinel tokens.
```py
import torch
from transformers import pipeline
- T5 uses relative scalar embeddings. Encoder input padding can be done on the left and on the right.
- See the [training](#training), [inference](#inference) and [resources](#resources) sections below for all details regarding usage.
T5 comes in different sizes:
- [google-t5/t5-small](https://huggingface.co/google-t5/t5-small)
- [google-t5/t5-base](https://huggingface.co/google-t5/t5-base)
- [google-t5/t5-large](https://huggingface.co/google-t5/t5-large)
- [google-t5/t5-3b](https://huggingface.co/google-t5/t5-3b)
- [google-t5/t5-11b](https://huggingface.co/google-t5/t5-11b).
Based on the original T5 model, Google has released some follow-up works:
- **T5v1.1**: T5v1.1 is an improved version of T5 with some architectural tweaks, and is pre-trained on C4 only without
mixing in the supervised tasks. Refer to the documentation of T5v1.1 which can be found [here](t5v1.1).
- **mT5**: mT5 is a multilingual T5 model. It is pre-trained on the mC4 corpus, which includes 101 languages. Refer to
the documentation of mT5 which can be found [here](mt5).
- **byT5**: byT5 is a T5 model pre-trained on byte sequences rather than SentencePiece subword token sequences. Refer
to the documentation of byT5 which can be found [here](byt5).
- **UL2**: UL2 is a T5 like model pretrained on various denoising objectives
- **Flan-T5**: Flan is a pretraining methods that is based on prompting. The Flan-T5 are T5 models trained on the Flan collection of
datasets which include: `taskmaster2`, `djaym7/wiki_dialog`, `deepmind/code_contests`, `lambada`, `gsm8k`, `aqua_rat`, `esnli`, `quasc` and `qed`.
- **FLan-UL2** : the UL2 model finetuned using the "Flan" prompt tuning and dataset collection.
- **UMT5**: UmT5 is a multilingual T5 model trained on an improved and refreshed mC4 multilingual corpus, 29 trillion characters across 107 language, using a new sampling method, UniMax. Refer to
the documentation of mT5 which can be found [here](umt5).
## Training
T5 is an encoder-decoder model and converts all NLP problems into a text-to-text format. It is trained using teacher
forcing. This means that for training, we always need an input sequence and a corresponding target sequence. The input
sequence is fed to the model using `input_ids`. The target sequence is shifted to the right, i.e., prepended by a
start-sequence token and fed to the decoder using the `decoder_input_ids`. In teacher-forcing style, the target
sequence is then appended by the EOS token and corresponds to the `labels`. The PAD token is hereby used as the
start-sequence token. T5 can be trained / fine-tuned both in a supervised and unsupervised fashion.
One can use [`T5ForConditionalGeneration`] (or the Tensorflow/Flax variant), which includes the
language modeling head on top of the decoder.
- Unsupervised denoising training
In this setup, spans of the input sequence are masked by so-called sentinel tokens (*a.k.a* unique mask tokens) and
the output sequence is formed as a concatenation of the same sentinel tokens and the *real* masked tokens. Each
sentinel token represents a unique mask token for this sentence and should start with `<extra_id_0>`,
`<extra_id_1>`, ... up to `<extra_id_99>`. As a default, 100 sentinel tokens are available in
[`T5Tokenizer`].
For instance, the sentence "The cute dog walks in the park" with the masks put on "cute dog" and "the" should be
processed as follows:
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> input_ids = tokenizer("The <extra_id_0> walks in <extra_id_1> park", return_tensors="pt").input_ids
>>> labels = tokenizer("<extra_id_0> cute dog <extra_id_1> the <extra_id_2>", return_tensors="pt").input_ids
>>> # the forward function automatically creates the correct decoder_input_ids
>>> loss = model(input_ids=input_ids, labels=labels).loss
>>> loss.item()
3.7837
pipeline = pipeline(
task="text2text-generation",
model="google-t5/t5-base",
torch_dtype=torch.float16,
device=0
)
pipeline("translate English to French: The weather is nice today.")
```

</hfoption>
<hfoption id="AutoModel">
- Supervised training
```py
import torch
from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
In this setup, the input sequence and output sequence are a standard sequence-to-sequence input-output mapping.
Suppose that we want to fine-tune the model for translation for example, and we have a training example: the input
sequence "The house is wonderful." and output sequence "Das Haus ist wunderbar.", then they should be prepared for
the model as follows:
tokenizer = AutoTokenizer.from_pretrained(
"google-t5/t5-base"
)
model = AutoModelForSeq2SeqLM.from_pretrained(
"google-t5/t5-base",
torch_dtype=torch.float16,
device_map="auto"
)
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
input_ids = tokenizer("translate English to French: The weather is nice today.", return_tensors="pt").to("cuda")
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> input_ids = tokenizer("translate English to German: The house is wonderful.", return_tensors="pt").input_ids
>>> labels = tokenizer("Das Haus ist wunderbar.", return_tensors="pt").input_ids
>>> # the forward function automatically creates the correct decoder_input_ids
>>> loss = model(input_ids=input_ids, labels=labels).loss
>>> loss.item()
0.2542
output = model.generate(**input_ids, cache_implementation="static")
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
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). The model will automatically create the `decoder_input_ids` based on the `labels`, by
shifting them one position to the right and prepending the `config.decoder_start_token_id`, which for T5 is
equal to 0 (i.e. the id of the pad token). Also note the task prefix: we prepend the input sequence with 'translate
English to German: ' before encoding it. This will help in improving the performance, as this task prefix was used
during T5's pre-training.
</hfoption>
<hfoption id="transformers-cli">
However, the example above only shows a single training example. In practice, one trains deep learning models in
batches. This entails that we must pad/truncate examples to the same length. For encoder-decoder models, one
typically defines a `max_source_length` and `max_target_length`, which determine the maximum length of the
input and output sequences respectively (otherwise they are truncated). These should be carefully set depending on
the task.
In addition, we must make sure that padding token id's of the `labels` are not taken into account by the loss
function. In PyTorch and Tensorflow, this can be done by replacing them with -100, which is the `ignore_index`
of the `CrossEntropyLoss`. In Flax, one can use the `decoder_attention_mask` to ignore padded tokens from
the loss (see the [Flax summarization script](https://github.com/huggingface/transformers/tree/main/examples/flax/summarization) for details). We also pass
`attention_mask` as additional input to the model, which makes sure that padding tokens of the inputs are
ignored. The code example below illustrates all of this.
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
>>> import torch
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> # the following 2 hyperparameters are task-specific
>>> max_source_length = 512
>>> max_target_length = 128
>>> # Suppose we have the following 2 training examples:
>>> input_sequence_1 = "Welcome to NYC"
>>> output_sequence_1 = "Bienvenue à NYC"
>>> input_sequence_2 = "HuggingFace is a company"
>>> output_sequence_2 = "HuggingFace est une entreprise"
>>> # encode the inputs
>>> task_prefix = "translate English to French: "
>>> input_sequences = [input_sequence_1, input_sequence_2]
>>> encoding = tokenizer(
... [task_prefix + sequence for sequence in input_sequences],
... padding="longest",
... max_length=max_source_length,
... truncation=True,
... return_tensors="pt",
... )
>>> input_ids, attention_mask = encoding.input_ids, encoding.attention_mask
>>> # encode the targets
>>> target_encoding = tokenizer(
... [output_sequence_1, output_sequence_2],
... padding="longest",
... max_length=max_target_length,
... truncation=True,
... return_tensors="pt",
... )
>>> labels = target_encoding.input_ids
>>> # replace padding token id's of the labels by -100 so it's ignored by the loss
>>> labels[labels == tokenizer.pad_token_id] = -100
>>> # forward pass
>>> loss = model(input_ids=input_ids, attention_mask=attention_mask, labels=labels).loss
>>> loss.item()
0.188
```bash
echo -e "translate English to French: The weather is nice today." | transformers-cli run --task text2text-generation --model google-t5/t5-base --device 0
```
Additional training tips:
</hfoption>
</hfoptions>
- T5 models need a slightly higher learning rate than the default one set in the `Trainer` when using the AdamW
optimizer. Typically, 1e-4 and 3e-4 work well for most problems (classification, summarization, translation, question
answering, question generation). Note that T5 was pre-trained using the AdaFactor optimizer.
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.
According to [this forum post](https://discuss.huggingface.co/t/t5-finetuning-tips/684), task prefixes matter when
(1) doing multi-task training (2) your task is similar or related to one of the supervised tasks used in T5's
pre-training mixture (see Appendix D of the [paper](https://arxiv.org/pdf/1910.10683.pdf) for the task prefixes
used).
The example below uses [torchao](../quantization/torchao) to only quantize the weights to int4.
If training on TPU, it is recommended to pad all examples of the dataset to the same length or make use of
*pad_to_multiple_of* to have a small number of predefined bucket sizes to fit all examples in. Dynamically padding
batches to the longest example is not recommended on TPU as it triggers a recompilation for every batch shape that is
encountered during training thus significantly slowing down the training. only padding up to the longest example in a
batch) leads to very slow training on TPU.
```py
# pip install torchao
import torch
from transformers import TorchAoConfig, AutoModelForSeq2SeqLM, AutoTokenizer
## Inference
quantization_config = TorchAoConfig("int4_weight_only", group_size=128)
model = AutoModelForSeq2SeqLM.from_pretrained(
"google/t5-v1_1-xl",
torch_dtype=torch.bfloat16,
device_map="auto",
quantization_config=quantization_config
)
At inference time, it is recommended to use [`~generation.GenerationMixin.generate`]. This
method takes care of encoding the input and feeding the encoded hidden states via cross-attention layers to the decoder
and auto-regressively generates the decoder output. Check out [this blog post](https://huggingface.co/blog/how-to-generate) to know all the details about generating text with Transformers.
There's also [this blog post](https://huggingface.co/blog/encoder-decoder#encoder-decoder) which explains how
generation works in general in encoder-decoder models.
tokenizer = AutoTokenizer.from_pretrained("google/t5-v1_1-xl")
input_ids = tokenizer("translate English to French: The weather is nice today.", return_tensors="pt").to("cuda")
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> input_ids = tokenizer("translate English to German: The house is wonderful.", return_tensors="pt").input_ids
>>> outputs = model.generate(input_ids)
>>> print(tokenizer.decode(outputs[0], skip_special_tokens=True))
Das Haus ist wunderbar.
output = model.generate(**input_ids, cache_implementation="static")
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
Note that T5 uses the `pad_token_id` as the `decoder_start_token_id`, so when doing generation without using
[`~generation.GenerationMixin.generate`], make sure you start it with the `pad_token_id`.
## Notes
The example above only shows a single example. You can also do batched inference, like so:
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> task_prefix = "translate English to German: "
>>> # use different length sentences to test batching
>>> sentences = ["The house is wonderful.", "I like to work in NYC."]
>>> inputs = tokenizer([task_prefix + sentence for sentence in sentences], return_tensors="pt", padding=True)
>>> output_sequences = model.generate(
... input_ids=inputs["input_ids"],
... attention_mask=inputs["attention_mask"],
... do_sample=False, # disable sampling to test if batching affects output
... )
>>> print(tokenizer.batch_decode(output_sequences, skip_special_tokens=True))
['Das Haus ist wunderbar.', 'Ich arbeite gerne in NYC.']
```
Because T5 has been trained with the span-mask denoising objective,
it can be used to predict the sentinel (masked-out) tokens during inference.
The predicted tokens will then be placed between the sentinel tokens.
```python
>>> from transformers import T5Tokenizer, T5ForConditionalGeneration
>>> tokenizer = T5Tokenizer.from_pretrained("google-t5/t5-small")
>>> model = T5ForConditionalGeneration.from_pretrained("google-t5/t5-small")
>>> input_ids = tokenizer("The <extra_id_0> walks in <extra_id_1> park", return_tensors="pt").input_ids
>>> sequence_ids = model.generate(input_ids)
>>> sequences = tokenizer.batch_decode(sequence_ids)
>>> sequences
['<pad> <extra_id_0> park offers <extra_id_1> the <extra_id_2> park.</s>']
```
## Performance
If you'd like a faster training and inference performance, install [NVIDIA APEX](https://github.com/NVIDIA/apex#quick-start) for NVIDIA GPUs, or [ROCm APEX](https://github.com/ROCmSoftwarePlatform/apex) for AMD GPUs and then the model will automatically use `apex.normalization.FusedRMSNorm` instead of `T5LayerNorm`. The former uses an optimized fused kernel which is several times faster than the latter.

🚀 **Deploy**
- A blog post on how to deploy [T5 11B for inference for less than $500](https://www.philschmid.de/deploy-t5-11b).
- You can pad the encoder inputs on the left or right because T5 uses relative scalar embeddings.
- T5 models need a slightly higher learning rate than the default used in [`Trainer`]. Typically, values of `1e-4` and `3e-4` work well for most tasks.

## Overview[[Overview]]
[Qwen2-VL](https://qwenlm.github.io/blog/qwen2-vl/) 모델은 알리바바 리서치의 Qwen팀에서 개발한 [Qwen-VL](https://arxiv.org/pdf/2308.12966) 모델의 주요 업데이트 버전입니다.
블로그의 요약은 다음과 같습니다:
*이 블로그는 지난 몇 년간 Qwen-VL에서 중대한 개선을 거쳐 발전된 Qwen2-VL 모델을 소개합니다. 중요 개선 사항은 향상된 이미지 이해, 고급 비디오 이해, 통합 시각 에이전트 기능, 확장된 다언어 지원을 포함하고 있습니다.모델 아키텍처는 Naive Dynamic Resolution 지원을 통해 임의의 이미지 해상도를 처리할 수 있도록 최적화되었으며, 멀티모달 회전 위치 임베딩(M-ROPE)을 활용하여 1D 텍스트와 다차원 시각 데이터를 효과적으로 처리합니다. 이 업데이트된 모델은 시각 관련 작업에서 GPT-4o와 Claude 3.5 Sonnet 같은 선도적인 AI 시스템과 경쟁력 있는 성능을 보여주며, 텍스트 능력에서는 오픈소스 모델 중 상위권에 랭크되어 있습니다. 이러한 발전은 Qwen2-VL을 강력한 멀티모달 처리 및 추론 능력이 필요한 다양한 응용 분야에서 활용할 수 있는 다재다능한 도구로 만들어줍니다.*

## 사용 예시[[Usage example]]
### 단일 미디어 추론[[Single Media inference]]
이 모델은 이미지와 비디오를 모두 인풋으로 받을 수 있습니다. 다음은 추론을 위한 예제 코드입니다.
```python
import torch
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
# 사용 가능한 장치에서 모델을 반 정밀도(half-precision)로 로드
model = Qwen2VLForConditionalGeneration.from_pretrained("Qwen/Qwen2-VL-7B-Instruct", device_map="auto")
processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-7B-Instruct")
conversation = [
{
"role":"user",
"content":[
{
"type":"image",
"url": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg"
},
{
"type":"text",
"text":"Describe this image."
}
]
}
]
inputs = processor.apply_chat_template(
conversation,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device)
# 추론: 아웃풋 생성
output_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, output_ids)]
output_text = processor.batch_decode(generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True)
print(output_text)
# 비디오
conversation = [
{
"role": "user",
"content": [
{"type": "video", "path": "/path/to/video.mp4"},
{"type": "text", "text": "What happened in the video?"},
],
}
]
inputs = processor.apply_chat_template(
conversation,
video_fps=1,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device)
# 추론: 아웃풋 생성
output_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, output_ids)]
output_text = processor.batch_decode(generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True)
print(output_text)
```
### 배치 혼합 미디어 추론[[Batch Mixed Media Inference]]
이 모델은 이미지, 비디오, 텍스트 등 다양한 유형의 데이터를 혼합하여 배치 입력으로 처리할 수 있습니다. 다음은 예제입니다.
```python
# 첫번째 이미지에 대한 대화
conversation1 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image1.jpg"},
{"type": "text", "text": "Describe this image."}
]
}
]
# 두 개의 이미지에 대한 대화
conversation2 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image2.jpg"},
{"type": "image", "path": "/path/to/image3.jpg"},
{"type": "text", "text": "What is written in the pictures?"}
]
}
]
# 순수 텍스트로만 이루어진 대화
conversation3 = [
{
"role": "user",
"content": "who are you?"
}
]
# 혼합된 미디어로 이루어진 대화
conversation4 = [
{
"role": "user",
"content": [
{"type": "image", "path": "/path/to/image3.jpg"},
{"type": "image", "path": "/path/to/image4.jpg"},
{"type": "video", "path": "/path/to/video.jpg"},
{"type": "text", "text": "What are the common elements in these medias?"},
],
}
]
conversations = [conversation1, conversation2, conversation3, conversation4]
# 배치 추론을 위한 준비
ipnuts = processor.apply_chat_template(
conversations,
video_fps=1,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device)
# 배치 추론
output_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(inputs.input_ids, output_ids)]
output_text = processor.batch_decode(generated_ids, skip_special_tokens=True, clean_up_tokenization_spaces=True)
print(output_text)
```
### 사용 팁[[Usage Tips]]
#### 이미지 해상도 트레이드오프[[Image Resolution trade-off]]
이 모델은 다양한 해상도의 입력을 지원합니다. 디폴트로 입력에 대해 네이티브(native) 해상도를 사용하지만, 더 높은 해상도를 적용하면 성능이 향상될 수 있습니다. 다만, 이는 더 많은 연산 비용을 초래합니다. 사용자는 최적의 설정을 위해 최소 및 최대 픽셀 수를 조정할 수 있습니다.
```python
min_pixels = 224*224
max_pixels = 2048*2048
processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```
제한된 GPU RAM의 경우, 다음과 같이 해상도를 줄일 수 있습니다:
```python
min_pixels = 256*28*28
max_pixels = 1024*28*28
processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
```
이렇게 하면 각 이미지가 256~1024개의 토큰으로 인코딩됩니다. 여기서 28은 모델이 14 크기의 패치(patch)와 2의 시간 패치(temporal patch size)를 사용하기 때문에 나온 값입니다 (14 × 2 = 28).
#### 다중 이미지 인풋[[Multiple Image Inputs]]
기본적으로 이미지와 비디오 콘텐츠는 대화에 직접 포함됩니다. 여러 개의 이미지를 처리할 때는 이미지 및 비디오에 라벨을 추가하면 참조하기가 더 쉬워집니다. 사용자는 다음 설정을 통해 이 동작을 제어할 수 있습니다:
```python
conversation = [
{
"role": "user",
"content": [
{"type": "image"},
{"type": "text", "text": "Hello, how are you?"}
]
},
{
"role": "assistant",
"content": "I'm doing well, thank you for asking. How can I assist you today?"
},
{
"role": "user",
"content": [
{"type": "text", "text": "Can you describe these images and video?"},
{"type": "image"},
{"type": "image"},
{"type": "video"},
{"type": "text", "text": "These are from my vacation."}
]
},
{
"role": "assistant",
"content": "I'd be happy to describe the images and video for you. Could you please provide more context about your vacation?"
},
{
"role": "user",
"content": "It was a trip to the mountains. Can you see the details in the images and video?"
}
]
# 디폴트:
prompt_without_id = processor.apply_chat_template(conversation, add_generation_prompt=True)
# 예상 아웃풋: '<|im_start|>system\nYou are a helpful assistant.<|im_end|>\n<|im_start|>user\n<|vision_start|><|image_pad|><|vision_end|>Hello, how are you?<|im_end|>\n<|im_start|>assistant\nI'm doing well, thank you for asking.

```
#### 빠른 생성을 위한 Flash-Attention 2[[Flash-Attention 2 to speed up generation]]
첫번째로, Flash Attention 2의 최신 버전을 설치합니다:
```bash
pip install -U flash-attn --no-build-isolation
```
또한, Flash-Attention 2를 지원하는 하드웨어가 필요합니다. 자세한 내용은 공식 문서인 [flash attention repository](https://github.com/Dao-AILab/flash-attention)에서 확인할 수 있습니다. FlashAttention-2는 모델이 `torch.float16` 또는 `torch.bfloat16` 형식으로 로드된 경우에만 사용할 수 있습니다.
Flash Attention-2를 사용하여 모델을 로드하고 실행하려면, 다음과 같이 모델을 로드할 때 `attn_implementation="flash_attention_2"` 옵션을 추가하면 됩니다:
```python
from transformers import Qwen2VLForConditionalGeneration
model = Qwen2VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2-VL-7B-Instruct",
torch_dtype=torch.bfloat16,
attn_implementation="flash_attention_2",
)

### Multi-GPU Evaluation
here is a command to run xsum evaluation on 8 GPUS. It is more than linearly faster than run_eval.py in some cases
here is a command to run xsum evaluation on 8 GPUs. It is more than linearly faster than run_eval.py in some cases
because it uses SortishSampler to minimize padding. You can also use it on 1 GPU. `data_dir` must have
`{type_path}.source` and `{type_path}.target`. Run `./run_distributed_eval.py --help` for all clargs.
