Can I train an AI model on CC0 material?
Last updated
TL;DR: Training a model: Yes. Training a model you use commercially: Yes. Creative Commons Zero v1.0 Universal (CC0-1.0): Dedicates the work to the public domain: copyright and related rights are waived as far as the law allows, with a fallback license where they cannot be.
Is training a model allowed under Creative Commons Zero v1.0 Universal?

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