OpenRAIL (Responsible AI License) is a family of model licenses that grant broad permission to use and distribute AI models while imposing use-based behavioral restrictions to prevent harmful applications.

OpenRAIL has become a common licensing framework for openly released foundation models and their training artifacts.
