**Short answer:** Training a model: Yes. Training a model you use commercially: Yes.

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