> I haven't seen anyone propose a rule that could be applied (much less an argument that would justify it as likely) based on copyright law that gets you to “used SD, in violation”. The speculative worst-case outcome for these tools that I've seen suggested is the legal system deciding that an image generated with them is a derivative work of every image that was used to train the model. Since none of these models were trained on images that they had rights releases for, this would mean they're incapable of outputting images that aren't infringing on the copyrights of vast numbers of people. I can't say how likely that is to actually be the legal outcome, of course, but it seems like the sort of concern that might lead to Valve's policy here.
