SD2 wasn’t “neutered”, the piece of it from OpenAI that knew a lot of artist names but wasn’t reproduceable was replaced with a new one from Stability that doesn’t. You can fine-tune anything you want back in.
The training-set was nerfed really good as well, it wasn't just OpenCLIP that was replaced. They will successively re-admit more training data during the 2.x releases I guess.
Yes, they removed some NSFW which might've hurt it, but releasing models that can generate CP /will/ get you in legal trouble.
The "in the style of Greg Rutkowski" prompts from SD1 though, IIRC, were thought to be proof it was reproducing the training set. But it actually only saw ~27 images of his, and the rest was residual biases from CLIP.
