Transformers
Version 5.17.0
Maintained by Hugging Face13
Transformers is Hugging Face's open-source Python library of model definitions for text, vision, audio, video, and multimodal models, used for both inference and training. Its README presents it as a shared model-definition layer that other training frameworks and inference engines build on, and it loads pretrained checkpoints from the Hugging Face Hub.12

Loading and running pretrained models through the high-level Pipeline API or model classes, fine-tuning them, and serving or chatting with a model from the command line.2
Run and use notes
- The installation guide documents offline use: download a model repository in advance and set HF_HUB_OFFLINE=1 (or pass local_files_only=True) so that loading does not contact the Hub.4
