Can I train an AI model on CDLA Permissive 2.0 material?
Last updated
TL;DR: Training a model: Yes. Training a model you use commercially: Yes.

Results of computational use, such as trained models, carry no restrictions or obligations.

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.
- Written for data and machine learning: the agreement places no restrictions or obligations on results such as trained models.
- Sublicensing is not documented.
