Can I train an AI model on GPL 3.0 material?
Last updated
TL;DR: Training a model: Needs review. Training a model you use commercially: Needs review. GNU General Public License v3.0 (GPL-3.0-only): Run, study, change and share the software, including commercially. If you convey it or a work based on it, you must do so under the GPL with the corresponding source.
Is training a model allowed under GNU General Public License v3.0?
Needs 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.

What else should I know?
- Whether a trained model is a copy or adaptation of its training data is legally unsettled; where the license does not settle it, a2ally marks training for human review instead of guessing.
- Sublicensing is not allowed; every recipient receives a license from the original licensors (sections 2 and 10).
- Running the software, including as a network service, does not by itself trigger the duty to share source; conveying copies does.
