Thanks for the links! To me (merely an amateur observer), it is not perfectly obvious that the LAION dataset is legal, because I don't think "we don't have your original images anymore, we only kept the results of applying an algorithm to them" is a universal defense. If the algorithm is "resize to 640×480" you are probably still infringing, but if it's "calculate md5 checksum" you're probably not. I don't know where on the spectrum LLM training will fall, legally!
