## 100k Transformers has just reached 100k stars on GitHub, and to celebrate we wanted to highlight 100 projects in the vicinity of `transformers` and we have decided to create an [awesome-transformers](https://github.com/huggingface/transformers/blob/main/awesome-transformers.md) page to do just that. We accept PRs to add projects to the list! * Top 100 by @LysandreJik in #22912 * Add LlamaIndex to awesome-transformers.md by @ravi03071991 in #23484 * add cleanlab to awesome-transformers tools list by @jwmueller in #23440 ## 4-bit quantization and QLoRA By leveraging the `bitsandbytes` library by @TimDettmers, we add 4-bit support to `transformers` models! * 4-bit QLoRA via bitsandbytes (4-bit base model + LoRA) by @TimDettmers in #23479 ## Agents The Agents framework has been improved and continues to be stabilized. Among bug fixes, here are the important new features that were added: - Local agent capabilities, to load a generative model directly from `transformers` instead of relying on APIs. - Prompts are now hosted on the Hub, which means that anyone can fork the prompts and update them with theirs, to let other community contributors re-use them - We add an `AzureOpenAiAgent` class to support Azure OpenAI agents. * Add local agent by @sgugger in #23438 * Enable prompts on the Hub by @sgugger in #23662 * Add AzureOpenAiAgent by @sgugger in #24058 ## Safetensors The `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 has now become a core dependency of `transformers`. * Making `safetensors` a core dependency. by @Narsil in #23254 ## New models ### Swiftformer The SwiftFormer paper introduces a novel efficient additive attention mechanism that effectively replaces the quadratic matrix multiplication operations in the self-attention computation with linear element-wise multiplications. A series of models called β€˜SwiftFormer’ is built based on this, which achieves state-of-the-art performance in terms of both accuracy and mobile inference speed. Even their small variant achieves 78.5% top-1 ImageNet1K accuracy with only 0.8 ms latency on iPhone 14, which is more accurate and 2Γ— faster compared to MobileViT-v2. * Add swiftformer by @shehanmunasinghe in #22686 ### Autoformer This model augments the Transformer as a deep decomposition architecture, which can progressively decompose the trend and seasonal components during the forecasting process. * [Time-Series] Autoformer model by @elisim in #21891 ### MobileViTv2 MobileViTV2 is the second version of MobileViT, constructed by replacing the multi-headed self-attention in MobileViT with separable self-attention. * Add MobileViTv2 by @shehanmunasinghe in #22820 ### PerSAM PerSAM proposes a minimal modification to [SAM](https://huggingface.co/docs/transformers/model_doc/sam) to allow dreambooth-like personalization, enabling to segment concepts in new images using just one example. * Add PerSAM [bis] by @NielsRogge in #23659 ## Timm backbone We add support for loading `timm` weights within the `AutoBackbone` API in `transformers`. `timm` models can be instantiated through the `TimmBackbone` class, and then used with any vision model that needs a backbone. * Add TimmBackbone model by @amyeroberts in #22619 ## Image to text pipeline conditional support We add conditional text generation to the image to text pipeline; allowing the model to continue generating an initial text prompt according to an image. * [image-to-text pipeline] Add conditional text support + GIT by @NielsRogge in #23362 ## TensorFlow implementations * Add TensorFlow implementation of EfficientFormer by @D-Roberts in #22620 ## Accelerate Migration A major rework of the internals of the `Trainer` is underway, leveraging `accelerate` instead of redefining them in `transformers`. This should unify both framework and lead to increased interoperability and more efficient development. * Smangrul/accelerate mp integrate by @pacman100 in #23148 * Smangrul/accelerate ddp integrate by @pacman100 in #23151 * fix trainer slow tests related to hyperparam search by @pacman100 in #24011 * remove the extra `accelerator.prepare` by @pacman100 in #23914 * move fsdp handling to accelerate by @pacman100 in #23158 * shift torch dynamo handling to accelerate by @pacman100 in #23168 * accelerate deepspeed and gradient accumulation integrate by @pacman100 in #23236 * fix
