Hugging Face Hub

Official Python client for the Hugging Face Hub. Handles model/dataset/Space downloading, uploading, caching, repo management, and Hub API interactions. Used as a dependency by transformers, datasets, sentence-transformers, and most HF ecosystem packages. The CLI was previously huggingface-cli; in v1.x it was rebranded as hf (also available as a standalone pip install hf package for CLI-only use). Import name: huggingface_hub (underscore). Package name: huggingface-hub (hyphen). These are different from the hf CLI package.
