Maybe a naive question, but if AI generated images are not copyrightable, wouldn't it be possible for some people to use it for research and for other people to re-use the results commercially?

I’m curious how they even thought of the idea to train a jigsaw puzzle like that in the first place. My naive guess was that those types of puzzles were preexisting. If in fact it’s a novel type of puzzle, that idea in itself is as cool as the generator they created!

I’m curious if they could ask for permission from the original authors (who doesn’t love a fun puzzle?—and it’s not like the profit motive here is alarming): most licenses are default permission.

You can always reach out and ask for a one-off in good faith.
