Hugging Face

Hugging Face is the leading open-source AI platform and community, often called the "GitHub of machine learning." Founded in 2016 by Clément Delangue, Julien Chaumond, and Thomas Wolf, the company has become the central hub where the AI community shares models, datasets, and applications.

The Hugging Face Hub hosts over 500,000 models, 100,000 datasets, and 200,000 demo applications (Spaces), making it the largest repository of open-source AI assets in the world. The company's Transformers library is the most widely used Python library for working with pre-trained models, and its ecosystem includes libraries for training (Accelerate), evaluation (Evaluate), and deployment (Inference Endpoints). Virtually every major AI research paper releases its models on Hugging Face.

Hugging Face has raised over $400 million at a $4.5 billion valuation, with investments from Google, Amazon, NVIDIA, and Salesforce. The company generates revenue through enterprise subscriptions (private model hosting, dedicated inference), while keeping its core community platform free. Hugging Face's role as the neutral repository for the entire AI ecosystem — hosting models from OpenAI, Meta, Google, and thousands of independent researchers — gives it an unmatched position in the AI developer community.
