**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.
- Trademark and patent rights are not waived (section 4(a)).
- No warranties are given (section 4(b)).
