Why some uses need review
AI model training. The license grants broad rights but attaches conditions (such as keeping notices) to copies and adaptations. Whether a trained model, or its output, is a copy or adaptation that carries those conditions is legally unsettled, and in some places training may fall under an exception such as fair use. A human reviewer should confirm this use for your case.

Notes
- Includes an express patent license that ends for anyone who sues over patents in the work (section 3).
