Hugging Face is the dominant open-source platform for machine learning — often called "GitHub for AI." Developers, researchers, and enterprises use it to discover, share, fine-tune, and deploy AI models, datasets, and interactive demo apps (called Spaces). As of May 2026, the Hub hosts 2.4M+ models, 730K+ datasets, and ~1M Spaces. The company also maintains the Transformers library (160K+ GitHub stars), a widely-used Python toolkit for running virtually any open-weight model. On the commercial side, it sells managed enterprise Hub deployments and dedicated inference endpoints, while routing serverless inference through an OpenAI-compatible gateway ("Inference Providers") connecting to Groq, Together, Fireworks, Cerebras, Replicate, Cohere, and 10+ others. More recently, Hugging Face acquired Pollen Robotics and launched LeRobot — an open robotics software stack — expanding into embodied AI. Revenue is estimated at ~$130M ARR (2024). Customers range from individual developers on $9/month plans to large enterprises paying for private, managed Hub instances.
