It's absolutely AI generated. I've messed with this model myself a few times. Edit: I believe it's Children's Stories V1 Toon-Anime Either that or something similar.
Still funny how a lot of people who try to pass off AI-generated art effectively give themselves away by disabling comments.
Or by not using any AI-related tags whatsoever. Didn't even realize this was AI generated until someone tagged it as such and I looked at the tags on the artist's other posts here.
