Hugging Face
huggingface.co
The central repository for open-source AI models, datasets, and Spaces demos — hosting over 1 million models and 150,000 datasets with free download and one-line API access.
Why it is useful
Became the de facto standard for sharing open-weight models, which means virtually every research model and fine-tune ends up here. The model cards document training data, intended use, and benchmarks in a consistent format that makes comparison practical. Free Spaces hosting means you can try most models in a browser before downloading anything.
