Hugging Face
The largest open-source AI model hub with 500K+ models, Spaces demos, and Inference Endpoints for developers.
Hugging Face is the central repository and collaboration platform for the open-source AI community. It hosts 500,000+ pre-trained models, datasets, and Spaces (interactive ML demo apps built with Gradio or Streamlit). Developers use it to discover and fine-tune LLMs, image models, audio models, and more. Inference Endpoints offer one-click dedicated GPU deployments. ZeroGPU provides free shared GPU compute for Spaces. The Transformers, Diffusers, PEFT, and TRL libraries maintained by HF are the backbone of modern AI research and production. With 42M monthly visitors, it is the most-visited AI developer platform in the world.
