- What is it?
- Hugging Face model cards (weights_format, license, sha256, download counts, risk_score). Pickle weights get a separate risk score because they execute arbitrary code on load.
- How do I use it?
- Before pulling a model with transformers, huggingface_hub, or Ollama, check this page (or GET /v1/ai/models/{purl}). Prefer the safetensors variant when weights_format is pickle; block when the license forbids commercial use.
- Why does it matter?
- Downloading a model is effectively installing "arbitrary code + a license". Pickle/.bin/.pt files run code at deserialize time, and a license violation can block a product launch overnight.
