Can I use AGPL 3.0 commercially, in AI training or with modifications?
As the GPL, plus: if you modify the software and let users interact with it over a network, you must offer them its corresponding source.
| Use | Answer | Why |
|---|---|---|
| commercial_use | Yes | Permitted, with duties: attribution, license_notice, state_changes, share_alike, source_disclosure, network_source_offer. |
| 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, share_alike, source_disclosure, network_source_offer. |
| redistribution | Yes | Permitted, with duties: attribution, license_notice, state_changes, share_alike, source_disclosure, network_source_offer. |
| model_inference | Yes | Permitted, with duties: attribution, license_notice, state_changes, share_alike, source_disclosure, network_source_offer. |
Duties
attribution, license_notice, state_changes, share_alike, source_disclosure, network_source_offer
