If you want to copyright the prompt, go right ahead. As far as I’m concerned that’s fair game; though I still think you’re a dumbass for getting mad about it.

As for the image? Fuck off. You can convince people that AI is capable of original works, or you can convince people that AI is nothing but a tool to remix and mashup other people’s artwork.

If you do the former, then the AI is the one that should receive copyright, not you. If the AI wants to then sell or transfer the copyright to you, then it’s free to do that… Except AI can’t hold copyright because there’s no evidence that it is intelligent enough to do so.

As for the latter? You’d better start going through your training set to make sure none of the trained images exist in the final image in a large enough capacity to be considered infringing. Otherwise, you may be liable for copyright infringement.

Either way, go fuck yourself.
