A pruned version is available if 12gb is too much.
Made this merge because some models were good at some things but not others and some at others but not some. This merge takes the best of all the models used makes a extremely versatile model. I merge sxzLuma, Incursio Meme Diffusion, autismmixpony together and then merged them to datassrev2, duchaiten35 and an unreleased one. Settings:
Sampler: I suggest Euler a with 30 steps or DPM++ 3M SDE Karras 25 steps
Resolution: I use 1360×1360, 904x1360, 1536x1024. As long as you use common aspect ratios like 1:1 or 2:3/3:2. You'll be fine.
CFG: 3 to 10, preferably. I prefer using 5 or below.
Hires fix settings: I don't usually use it so I can't say for certain but 10 steps should be fine.
