Why some uses need review
AI model training. 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.
