Hugging Face began as a chatbot startup and grew into what is now widely described as the home of machine learning. The core of the product is the Hub: a public, searchable registry of model weights, datasets, and interactive Spaces demos. On a typical visit you will see millions of models ranging from large language and vision models published by major labs to small fine-tunes shared by individual developers, each with model cards, libraries, and one-click inference options.
Around that registry Hugging Face has built a full working stack. Its open-source libraries — Transformers, Diffusers, Datasets, Tokenizers, Accelerate, PEFT, TRL, and smolagents — power a large share of modern training and inference pipelines, and the Hub integrates directly with them. Teams can also move beyond public hosting: Inference Providers give a single API across tens of thousands of hosted models, Inference Endpoints deploy dedicated GPUs, and Enterprise plans add SSO, audit logs, private datasets, and priority support.
The platform is free to browse, upload, and collaborate on for public content, with paid tiers for individuals, teams, and enterprises that need private storage, higher limits, and compute. Because the community continuously publishes papers, blog posts, daily papers digests, and leaderboards in the same place, Hugging Face doubles as a discovery layer for what is happening in AI right now.
