Licensing

Also known as: model license · license

Security

Licensing defines what you’re allowed to do with a model or dataset: use it, fine-tune it, serve it commercially, redistribute it.

  • Open weights: you can download and run; terms vary.
  • Permissive (Apache/MIT): broad commercial rights.
  • Restrictive / custom: usage caps, attribution, or no-redistribution.

Read it before you ship: a model can be freely downloadable and still restrict commercial use. The license, not the download button, is the real contract.
