HillMix

It does the big booba lol.

I made this on a whim trying to replicate someone else's generation but this is actually fairly decent. It's pretty good at doing fantasy and cultural stuff in a sort of illustrative, not quite cartoon but also not quite realistic style. IME you're best using this either for full body portraits or epic fantasy scenes.

HuggingFace for recipe.

UsageI dunno lol. I mostly just stole prompts from ReV Animated and UmiAI fantasy mix. It seems to do both booru style tags and prose prompts pretty well. Try mixing and matching. It's surprisingly responsive to prompts so I figure that probably all the merging has fed it a bunch of weights and normalized their bias.

As to the upscaler, any GAN type upscaler will work fine. Latent sometimes works but is more finicky than not.
