You need a very specific prompt to make a copy. Even to just be similar enough you have to put the proper input and try a lot of repetitions.

That’s why the right holders are going after the training which included copying by the AI corpos.

In your dream land right holders could just prompt the AI till it spit something close to their work and sue the AI corp for that. Repeat as needed ; infinite money glitch.

Obviously it doesn’t work that way.
