Are you talking about an artist exclusively running their images through an AI model until it is capable of regenerating images that look like it was created by them and have some semblance of intent?
In order to get anything that looks remotely like what people want, I'm pretty sure they would have to upload millions of pictures of their own creation first. So most people just layer their images on top of the giant mash of ethically sketchy data that already was there.
What @model_tar_gz@lemmy.world said, Sorry my original post was not so clear.
I based my answer on the assumption that you would not be using somebody else's art to train an AI. The Lora models are already brimming full of other people's art.
