Hugging Face
The open-model hub and de facto distribution registry
Hugging Face hosts the model weights, datasets, and libraries (Transformers, Diffusers) that function as the GitHub of open AI, with well over a million models. It is the neutral distribution layer that lets Llama, Mistral, Qwen, and DeepSeek reach developers. Control of this registry shapes which open models get adopted.
