i already told you, it's Illustrious, and it's various versions, i don't know which version exactly i downloaded and where it was a long time ago, create clean inpaint workflow, download 10 various checkpoints and test what they are capable of, that is what i did back in a day, problem with checkpoints they can't publicly write "it can guro", just need download many of them and test. but i think it was these ones which certainly have guro
