Ok, that doesn't address my point though: Do we agree that in the _real_ world, it is impossible to determine which image have been used to generate the model (not talking about just the LORA part here). So the solution i see is: - we ban AI-generated image from public use because of IP: basically, the use of any image not in the public domain, even CC0, will cause that - Most non-public-domain images on the internet you can use to train stuff are CC and CC0 (which is kinda public domain if i remember my wikipedia days). My point is: the majority of the images used to create the model (again, not the LORA part) are public domain or free to use as long as they are attributed. It's impossible to attribute according to what CC is demanding. The list would be impossible to find. So either we get back to the first sentence, and sue AI-generated images to oblivion, or the image are public domain/CC0. Also, the legal point: the creator of the art isn't a human, so it isn't copyrightable. A curator do not have the copyright of the image/painting he found at a garage sale, even if he put a lot of effort to restore it.
