Hugging Face has announced the launch of Transformers version 4.42which brings many new features and improvements to the popular machine learning library. This release introduces several advanced models, supports new tools and Recall Augmented Generation (RAG), offers fine-tuning of GGUF, and introduces a quantized KV cache, among other improvements.
With Transformers version 4.42, this release of new models including Gemma 2, RT-DETR, InstructBlip and LLaVa-NeXT-Video also makes it more noticeable. The Gemma 2 model family, developed by Google's Gemma2 team, consists of two versions: 2 billion and 7 billion parameters. These models are trained on 6 billion tokens and have shown remarkable performance on several academic benchmarks in language understanding, reasoning, and security. They outperformed similarly sized open models on 11 of 18 text-based tasks, showing their strong capabilities and responsible development practices.
RT-DETR, or Real-Time Detection Transformer, is another important addition. Designed for real-time object detection, this model takes advantage of the transformer architecture to quickly and accurately identify and locate multiple objects within images. Its development positions it as a formidable competitor in object detection models.
InstructBlip improves the matching of visual instructions using the BLIP-2 architecture. It sends text prompts to the Q-Former, allowing for more effective interactions between the visual model and the language model. This model promises improved performance on tasks that require both visual and textual understanding.
LLaVa-NeXT-Video builds on the LLaVa-NeXT model by incorporating video and image datasets. This enhancement enables the model to perform state-of-the-art video understanding tasks, making it a valuable tool for zero-shot video content analysis. The AnyRes technique, which represents high-resolution images as multiple smaller images, is crucial to this model's ability to effectively generalize images to video frames.
Tooling usability and RAG support have also been significantly improved. Hugging Face automatically generates JSON schema descriptions for Python functions, facilitating seamless integration with tooling models. A standardized API for tooling models ensures compatibility across multiple implementations, targeting the Nous-Hermes, Command-R, and Mistral/Mixtral model families for imminent compatibility.
Another notable improvement is support for GGUF fine-tuning. This feature allows users to fine-tune models within the Python/Hugging Face ecosystem and then convert them back to GGUF/GGML/llama.cpp libraries. This flexibility ensures that models can be optimized and deployed in a variety of environments.
Quantization improvements, including the addition of a quantized KV cache, further reduce memory requirements for generative models. This update, along with a comprehensive overhaul of the quantization documentation, provides users with clearer guidance for selecting the most appropriate quantization methods for their needs.
In addition to these major updates, Transformers 4.42 includes several other improvements. New instance segmentation examples have been added, allowing users to leverage weights from pre-trained Hugging Face models as the backbone of vision models. The release also includes bug fixes and optimizations, as well as the removal of deprecated components such as ConversationalPipeline and the Conversation object.
In conclusion, Transformers 4.42 represents a significant development for the Hugging Face machine learning library. With its new models, improved tool support, and numerous optimizations, this release consolidates Hugging Face’s position as a leader in NLP and machine learning.
