Hugging Face

Hugging Face operates the most important platform infrastructure for the open AI ecosystem: a model hub hosting over one million model weights, a datasets repository, and Spaces for running AI applications. It was the founding organisation of the BigScience workshop that produced BLOOM, and hosts the Open LLM Leaderboard. Hugging Face is the primary distribution channel for open-weight models from Meta, Mistral, and hundreds of research institutions. Its position as neutral infrastructure provider gives it unusual visibility into the commercial and research AI landscape. The company raised $235 million in 2023 at a $4.5 billion valuation.
