Can I use Apache 2.0 commercially, in AI training or with modifications?
Use, reproduce, modify, sublicense and distribute for any purpose, with an express patent license; keep notices, include the license and mark changed files.
| Use | Answer | Why |
|---|---|---|
| commercial_use | Yes | Permitted, with duties: attribution, license_notice, state_changes. |
| model_training | Needs human review | 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. |
| modification | Yes | Permitted, with duties: attribution, license_notice, state_changes. |
| redistribution | Yes | Permitted, with duties: attribution, license_notice, state_changes. |
| model_inference | Yes | Permitted, with duties: attribution, license_notice, state_changes. |
