About
Hugging Face is the de facto home for the global machine learning community, providing a collaborative platform to discover, share, and deploy state-of-the-art AI models, datasets, and applications. With over 2 million models, 500,000+ datasets, and 1 million+ AI-powered applications (Spaces), it is the most comprehensive AI model repository in existence. The platform underpins modern AI development through a rich ecosystem of open-source libraries including Transformers (157k+ GitHub stars), Diffusers, Tokenizers, PEFT, TRL, smolagents, and Transformers.js — tools that power research and production workloads worldwide. Developers can access 45,000+ models from leading AI providers through a unified Inference API with no service fees. Hugging Face serves a wide audience: individual researchers can host unlimited public models and datasets for free and build their ML portfolio, while enterprises get advanced security, SSO, audit logs, resource groups, and dedicated support starting at $20/user/month. GPU-accelerated Inference Endpoints and Spaces allow seamless deployment of AI applications starting at $0.60/hour. Trusted by over 50,000 organizations — including Google, Microsoft, Meta, Amazon, and Intel — Hugging Face has become an essential infrastructure layer for AI development, democratizing access to frontier models and fostering collaboration across academia and industry.
