Unity's AI-based content generator has been created with a custom-built and as Unity mentioned "responsibly" trained model. So that creators don't have to worry about using someone else's copyrighted content.
In fact, Unity is so confident about the results generated by their AI model that they will partner to defend creators in the unlikely event of a copyright issue!
