A model-definition framework for state-of-the-art machine learning models across text, vision, audio, and multimodal tasks.
Transformers is a Python library and model-definition framework for state-of-the-art machine learning across text, vision, audio, and multimodal domains. It provides a unified API for using, training, and sharing pretrained models, acting as a central standard that ensures compatibility with numerous ML tools and frameworks. The library simplifies access to over a million models, reducing the barrier to entry for advanced AI applications.
Machine learning researchers, engineers, and developers who need to work with state-of-the-art models for NLP, computer vision, audio, or multimodal tasks, whether for research, prototyping, or production deployment.
Developers choose Transformers for its extensive model support, framework interoperability, and the vast Hugging Face Hub ecosystem. Its unified API and central model definition reduce complexity and enable seamless integration with the broader ML toolchain, from training to inference.
🤗 Transformers: the model-definition framework for state-of-the-art machine learning models in text, vision, audio, and multimodal models, for both inference and training.

Centralizes model definitions for compatibility across training frameworks like DeepSpeed and inference engines like vLLM, as highlighted in the README's pivot diagram, ensuring seamless integration.
Provides access to over 1M+ model checkpoints on Hugging Face Hub, reducing the need to train from scratch and lowering compute costs, as stated in the key features.
Offers a high-level Pipeline API for quick tasks like text generation and speech recognition with minimal code, demonstrated in the quickstart examples for various modalities.
Handles text, vision, audio, and multimodal models for both inference and training, with examples spanning from image classification to visual question answering in the README.
The library intentionally avoids additional abstractions in model files, making it less suitable for researchers who need to quickly iterate on custom architectures without refactored building blocks.
The training API is optimized specifically for PyTorch models from Transformers; for generic machine learning loops, users must rely on external libraries like Accelerate, as admitted in the README.
Provided example scripts may not work out-of-the-box for specific use cases and often require significant modification, which can increase development time and complexity.
