New model additions

Mixtral

Mixtral is the new open-source model from Mistral AI announced by the blogpost [Mixtral of Experts](https://mistral.ai/news/mixtral-of-experts/). The model has been proven to have comparable capabilities to Chat-GPT according to the benchmark results shared on the release blogpost.

The architecture is a sparse Mixture of Experts with Top-2 routing strategy, similar as `NllbMoe` architecture in transformers. You can use it through `AutoModelForCausalLM` interface:

py
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer

>>> model = AutoModelForCausalLM.from_pretrained("mistralai/Mixtral-8x7B", torch_dtype=torch.float16, device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-8x7B")

>>> prompt = "My favourite condiment is"

>>> model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
>>> model.to(device)

>>> generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]


The model is compatible with existing optimisation tools such Flash Attention 2, `bitsandbytes` and PEFT library. The checkpoints are release under [`mistralai`](https://huggingface.co/mistralai) organisation on the Hugging Face Hub.

Llava / BakLlava

Llava is an open-source chatbot trained by fine-tuning LlamA/Vicuna on GPT-generated multimodal instruction-following data. It is an auto-regressive language model, based on the transformer architecture. In other words, it is an multi-modal version of LLMs fine-tuned for chat / instructions.

The Llava model was proposed in [Improved Baselines with Visual Instruction Tuning](https://arxiv.org/pdf/2310.03744) by Haotian Liu, Chunyuan Li, Yuheng Li and Yong Jae Lee.

* [`Llava`] Add Llava to transformers by younesbelkada in 27662
* [LLaVa] Some improvements by NielsRogge in 27895

The integration also includes [`BakLlava`](https://github.com/SkunkworksAI/BakLLaVA) which is a Llava model trained with Mistral backbone.

The mode is compatible with `"image-to-text"` pipeline:

py
from transformers import pipeline
from PIL import Image
import requests

model_id = "llava-hf/llava-1.5-7b-hf"
pipe = pipeline("image-to-text", model=model_id)
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/ai2d-demo.jpg"

image = Image.open(requests.get(url, stream=True).raw)
prompt = "USER: <image>\nWhat does the label 15 represent? (1) lava (2) core (3) tunnel (4) ash cloud\nASSISTANT:"

outputs = pipe(image, prompt=prompt, generate_kwargs={"max_new_tokens": 200})
print(outputs)


And you can find all Llava weights under [`llava-hf`](https://huggingface.co/llava-hf) organisation on the Hub.

SeamlessM4T v2

SeamlessM4T-v2 is a collection of models designed to provide high quality translation, allowing people from different linguistic communities to communicate effortlessly through speech and text. It is an improvement on the [previous version](https://huggingface.co/docs/transformers/v4.36.0/en/model_doc/seamless_m4t.md) and was proposed in [Seamless: Multilingual Expressive and Streaming Speech Translation](https://ai.meta.com/research/publications/seamless-multilingual-expressive-and-streaming-speech-translation/) by the Seamless Communication team from Meta AI.

For more details on the differences between v1 and v2, refer to section [Difference with SeamlessM4T-v1](https://huggingface.co/docs/transformers/v4.36.0/en/model_doc/seamless_m4t_v2#difference-with-seamlessm4t-v1).

SeamlessM4T enables multiple tasks without relying on separate models:

- Speech-to-speech translation (S2ST)
- Speech-to-text translation (S2TT)
- Text-to-speech translation (T2ST)
- Text-to-text translation (T2TT)
- Automatic speech recognition (ASR)


* Add SeamlessM4T v2 by ylacombe in 27779

PatchTST

The PatchTST model was proposed in [A Time Series is Worth 64 Words: Long-term Forecasting with Transformers](https://arxiv.org/abs/2211.14730) by Yuqi Nie, Nam H. Nguyen, Phanwadee Sinthong and Jayant Kalagnanam.

At a high level, the model vectorizes time series into patches of a given size and encodes the resulting sequence of vectors via a Transformer that then outputs the prediction length forecast via an appropriate head. The model is illustrated in the following figure:



* [Time series] Add PatchTST by psinthong in 25927
* [Time series] Add PatchTST by kashif in 27581

PatchTSMixer

The PatchTSMixer model was proposed in [TSMixer: Lightweight MLP-Mixer Model for Multivariate Time Series Forecasting](https://arxiv.org/pdf/2306.09364.pdf) by Vijay Ekambaram, Arindam Jati, Nam Nguyen, Phanwadee Sinthong and Jayant Kalagnanam.

PatchTSMixer is a lightweight time-series modeling approach based on the MLP-Mixer architecture. In this HuggingFace implementation, we provide PatchTSMixer’s capabilities to effortlessly facilitate lightweight mixing across patches, channels, and hidden features for effective multivariate time-series modeling. It also supports various attention mechanisms starting from simple gated attention to more complex self-attention blocks that can be customized accordingly. The model can be pretrained and subsequently used for various downstream tasks such as forecasting, classification and regression.

* [Time series] Add PatchTSMixer by ajati in 26247

CLVP

The CLVP (Contrastive Language-Voice Pretrained Transformer) model was proposed in [Better speech synthesis through scaling](https://arxiv.org/abs/2305.07243) by James Betker.

* Add CLVP by susnato in 24745

A patch release was made for the following commit:

- [`tokenizers`] update tokenizers version pin 27494

to fix all the issues with versioning regarding `tokenizers` and `huggingface_hub`

A patch release was made for the following three commits:

- Fix FA2 import + deprecation cycle (27330)
- Fix from_pt flag when loading with safetensors (27394)
- Default to msgpack for safetensors (27460)

New models

Distil-Whisper

Distil-Whisper is a distilled version of Whisper that is 6 times faster, 49% smaller, and performs within 1% word error rate (WER) on out-of-distribution data. It was proposed in the paper [Robust Knowledge Distillation via Large-Scale Pseudo Labelling](https://arxiv.org/abs/2311.00430).

Distil-Whisper copies the entire encoder from Whisper, meaning it retains Whisper's robustness to different audio conditions. It only copies 2 decoder layers, which significantly reduces the time taken to auto-regressively generate text tokens:

<img src="https://huggingface.co/datasets/distil-whisper/figures/resolve/main/architecture.png" width="800">

Distil-Whisper is MIT licensed and directly available in the Transformers library with chunked long-form inference, Flash Attention 2 support, and Speculative Decoding. For details on using the model, refer to the [following instructions](https://github.com/huggingface/distil-whisper#1-usage).

Fuyu


The Fuyu model was created by [ADEPT](https://www.adept.ai/blog/fuyu-8b), and authored by Rohan Bavishi, Erich Elsen, Curtis Hawthorne, Maxwell Nye, Augustus Odena, Arushi Somani, Sağnak Taşırlar.

The authors introduced Fuyu-8B, a decoder-only multimodal model based on the classic transformers architecture, with query and key normalization. A linear encoder is added to create multimodal embeddings from image inputs.

By treating image tokens like text tokens and using a special image-newline character, the model knows when an image line ends. Image positional embeddings are removed. This avoids the need for different training phases for various image resolutions. With 8 billion parameters and licensed under CC-BY-NC, Fuyu-8B is notable for its ability to handle both text and images, its impressive context size of 16K, and its overall performance.

Joint work from molbap, pcuenca, amyeroberts, ArthurZucker

* Fuyu: improve image processing by molbap in 27007

SeamlessM4T


The SeamlessM4T model was proposed in [SeamlessM4T — Massively Multilingual & Multimodal Machine Translation](https://dl.fbaipublicfiles.com/seamless/seamless_m4t_paper.pdf) by the Seamless Communication team from Meta AI.

SeamlessM4T is a collection of models designed to provide high quality translation, allowing people from different linguistic communities to communicate effortlessly through speech and text.

SeamlessM4T enables multiple tasks without relying on separate models:

- Speech-to-speech translation (S2ST)
- Speech-to-text translation (S2TT)
- Text-to-speech translation (T2ST)
- Text-to-text translation (T2TT)
- Automatic speech recognition (ASR)

[SeamlessM4TModel](https://huggingface.co/docs/transformers/main/en/model_doc/seamless_m4t#transformers.SeamlessM4TModel) can perform all the above tasks, but each task also has its own dedicated sub-model.

* Add Seamless M4T model by ylacombe in 25693

Kosmos-2

The KOSMOS-2 model was proposed in [Kosmos-2: Grounding Multimodal Large Language Models to the World](https://arxiv.org/abs/2306.14824) by Zhiliang Peng, Wenhui Wang, Li Dong, Yaru Hao, Shaohan Huang, Shuming Ma, Furu Wei.

<div style="text-align: center">
<img src="https://huggingface.co/microsoft/kosmos-2-patch14-224/resolve/main/annotated_snowman.jpg" width="500" height="400" >
</div>

KOSMOS-2 is a Transformer-based causal language model and is trained using the next-word prediction task on a web-scale dataset of grounded image-text pairs [GRIT](https://huggingface.co/datasets/zzliang/GRIT). The spatial coordinates of the bounding boxes in the dataset are converted to a sequence of location tokens, which are appended to their respective entity text spans (for example, a snowman followed by <patch_index_0044><patch_index_0863>). The data format is similar to “hyperlinks” that connect the object regions in an image to their text span in the corresponding caption.

* Add `Kosmos-2` model by ydshieh in 24709

Owl-v2

OWLv2 was proposed in [Scaling Open-Vocabulary Object Detection](https://arxiv.org/abs/2306.09683) by Matthias Minderer, Alexey Gritsenko, Neil Houlsby. OWLv2 scales up [OWL-ViT](https://huggingface.co/docs/transformers/main/en/model_doc/owlvit) using self-training, which uses an existing detector to generate pseudo-box annotations on image-text pairs. This results in large gains over the previous state-of-the-art for zero-shot object detection.

* Add OWLv2, bis by NielsRogge in 26668

🚨🚨🚨 Safetensors by default for `torch` serialization 🚨🚨🚨

Version v4.35.0 now puts `safetensors` serialization by default. This is a significant change targeted at making users of the Hugging Face Hub, `transformers`, and any downstream library leveraging it safer.

The [`safetensors`](https://github.com/huggingface/safetensors) library is a safe serialization framework for machine learning tensors. It has been audited and will become the default serialization framework for several organizations (Hugging Face, EleutherAI, Stability AI).

It was already the **default loading mechanism** since v4.30.0 and would therefore already default to loading `model.safetensors` files instead of `pytorch_model.bin` if these were present in the repository.

With v4.35.0, any call to `save_pretrained` for torch models will now save a `safetensors` file. This `safetensors` file is in the PyTorch format, but can be loaded in TensorFlow and Flax models alike.

⚠️ If you run into any issues with this, please let us know ASAP in the issues so that we may help you. Namely, the following errors may indicate something is up:
- Loading a `safetensors` file and having a warning mentioning missing weights unexpectedly
- Obtaining completely wrong/random results at inference after loading a pretrained model that you have saved in `safetensors`

If you wish to continue saving files in the `.bin` format, you can do so by specifying `safe_serialization=False` in all your `save_pretrained` calls.

* Safetensors serialization by default by LysandreJik in 27064

Chat templates

Chat templates have been expanded with the addition of the `add_generation_prompt` argument to `apply_chat_template()`. This has also enabled us to rework the [ConversationalPipeline](https://huggingface.co/docs/transformers/main/en/main_classes/pipelines#transformers.ConversationalPipeline) class to use chat templates. Any model with a chat template is now automatically usable through `ConversationalPipeline`.

* Add add_generation_prompt argument to apply_chat_template by Rocketknight1 in 26573
* Conversation pipeline fixes by Rocketknight1 in 26795

Guides

Two new guides on LLMs were added the library:

* [docs] LLM prompting guide by MKhalusova in 26274
* [docs] Optimizing LLMs by patrickvonplaten in 26058

Quantization

Exllama-v2 integration

Exllama-v2 provides better GPTQ kernel for higher throughput and lower latency for GPTQ models. The original [code](https://github.com/turboderp/exllamav2) can be found here.

* add exllamav2 arg by SunMarc in 26437
* Add exllamav2 better by SunMarc in 27111

You will need the latest versions of `optimum` and `auto-gptq`. Read more about the integration [here](https://huggingface.co/docs/transformers/main/en/main_classes/quantization#exllama-kernels-for-faster-inference).

AWQ integration

AWQ is a new and popular quantization scheme, already used in various libraries such as TGI, vllm, etc. and known to be faster than GPTQ models according to some benchmarks. The original code can be found [here](https://github.com/mit-han-lab/llm-awq/) and [here](https://arxiv.org/abs/2306.00978) you can read more about the original paper.


We support AWQ inference with original kernels as well as kernels provided through [`autoawq`](https://github.com/casper-hansen/AutoAWQ/) package that you can simply install with `pip install autoawq`.

* [`core` / `Quantization` ] AWQ integration by younesbelkada in 27045

We also provide an example script on [how to push quantized weights on the hub on the original repository](https://github.com/mit-han-lab/llm-awq/blob/main/examples/convert_to_hf.py).

Read more about the benchmarks and the integration [here](https://huggingface.co/docs/transformers/main/en/main_classes/quantization#awq-integration)

GPTQ on CPU !

You can now run GPTQ models on CPU using the latest version of `auto-gptq` thanks to vivekkhandelwal1 !

* Add support for loading GPTQ models on CPU by vivekkhandelwal1 in 26719

Attention mask refactor

We refactored the attention mask logic for major models in transformers. For instance, we removed `padding_mask` argument which was ambiguous for some users

* Remove ambiguous `padding_mask` and instead use a 2D->4D Attn Mask Mapper by patrickvonplaten in 26792
* [Attention Mask] Refactor all encoder-decoder attention mask by patrickvonplaten in 27086


Flash Attention 2 for more models + quantization fine-tuning bug fix

`Gpt-bigcode` (starcoder), whisper, Bart and MBart now supports FA-2 ! Use it by simply passing `use_flash_attention_2=True` to `from_pretrained`. Some bugfixes with respect to mixed precision training with FA2 have been also addressed.

* Add flash attention for `gpt_bigcode` by susnato in 26479
* [`FA2`] Fix flash attention 2 fine-tuning with Falcon by younesbelkada in 26852
* [Whisper, Bart, MBart] Add Flash Attention 2 by patrickvonplaten in 27203

A bugfix with respect to fine-tuning with FA-2 in bfloat16 was addressed. You should now smoothly fine-tune FA-2 models in bfloat16 using quantized base models.

* 🚨🚨🚨 [`Quantization`] Store the original dtype in the config as a private attribute 🚨🚨🚨 by younesbelkada in 26761
* [`FA-2`] Final fix for FA2 dtype by younesbelkada in 26846

Neftune

NEFTune is a new technique to boost Supervised Fine-tuning performance by adding random noise on the embedding vector. Read more about it on the original paper [here](https://arxiv.org/abs/2310.05914)


We propose a very simple API for users to benefit from this technique, simply pass a valid `neftune_noise_alpha` parameter to `TrainingArguments`

Read more about the API [here](https://huggingface.co/docs/transformers/main/en/main_classes/trainer#boost-your-fine-tuning-performances-using-neftune)

* [FEAT] Add Neftune into transformers Trainer by younesbelkada in 27141

Gradient checkpointing refactor

We have refactored the gradient checkpointing API so that users can pass keyword arguments supported by `torch.utils.checkpoint.checkpoint` directly through `gradient_checkpointing_kwargs` when calling `gradient_checkpointing_enable()`, e.g.

python
from transformers import AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained("facebook/opt-125m")
model.gradient_checkpointing_enable(gradient_checkpointing_kwargs={"use_reentrant": False})


`gradient_checkpointing_kwargs` is also supported with `Trainer` through `TrainingArguments`.

* [`Trainer` / `GC`] Add `gradient_checkpointing_kwargs` in trainer and training arguments by younesbelkada in 27068
* [`core`] Refactor of `gradient_checkpointing` by younesbelkada in 27020
* [`core`/ `GC` / `tests`] Stronger GC tests by younesbelkada in 27124
* Fix import of torch.utils.checkpoint by NielsRogge in 27155

The refactor should be totally backward compatible with previous behaviour. For superusers, you can still use the attribute `gradient_checkpointing` on model's submodules to control the activation / deactivation of gradient_checkpointing.
