Definition
Plain language
An online hub where people share and download AI models and datasets.
As stated in the literature
A platform and library ecosystem for hosting, sharing, and running open-weight models and datasets; the de facto standard registry referenced when papers release weights.
Why it matters: It's the common meeting place for sharing open models and datasets, which is much of what makes open AI research reproducible and accessible.
For example, after a team releases an open model, anyone can download it from Hugging Face and start using it the same day.
