# Can I train an AI model on CC BY-ND 4.0 material?

**Short answer:** Training a model: Needs review. Training a model you use commercially: Needs review.

Creative Commons Attribution-NoDerivatives 4.0 International (CC-BY-ND-4.0): Share the material unchanged for any purpose, including commercially, with credit. Adaptations may be made for yourself but not shared.

## Training a model — Needs review

License: [Creative Commons Attribution-NoDerivatives 4.0 International](https://creativecommons.org/licenses/by-nd/4.0/legalcode) (`CC-BY-ND-4.0`, curated)

- Creative Commons licenses grant rights to reproduce and adapt the material, with conditions that apply when it or an adaptation is shared. Whether training a model creates an adaptation, and how attribution applies to a trained model or its output, is not settled; Creative Commons notes that training may also fall under exceptions such as fair use. A human reviewer should confirm this use for your case.

## 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.
- The grant is non-sublicensable: every recipient receives the license directly from the licensor (section 2(a)(5)).
- You may not apply legal terms or technical measures that restrict recipients from exercising the licensed rights (section 2(a)(5)(C)).
