Not to say that I don't understand people's arguments. I think that being able to type a living artist's name into a prompt and emulate their style could represent an infringement, but there needs to be a sense of nuance. I don't think that training models on copyrighted materials is infringing at all. The data a model was trained on doesn't exist inside the model, so it doesn't really count as a copy.
And prompts that don't evoke a specific artist don't produce works that infringe on anyone.
This is the Vranas instance.
