# Can I train an AI model on Apache 2.0 material?

**Short answer:** Training a model: Needs review. Training a model you use commercially: Needs review.

Apache License 2.0 (Apache-2.0): Use, reproduce, modify, sublicense and distribute for any purpose, with an express patent license; keep notices, include the license and mark changed files.

## Training a model — Needs review

License: [Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0) (`Apache-2.0`, curated)

- 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.

Duties: attribution, license_notice, state_changes

## Context
- Whether a trained model is a copy or adaptation of its training data is legally unsettled; where the license does not settle it, Rightshold marks training for human review instead of guessing.
- Includes an express patent license that ends for anyone who sues over patents in the work (section 3).
- Does not grant rights to the licensor's trademarks (section 6).
