For best outputs:

Sampler: DPM++ 2M Karras

Steps: 25, cfg 7, CLIP skip 2.

No VAE or adetailer needed.

Neg: nothing or just something simple, like e.g. "bad face, low quality, lowres, bad face, bad anatomy"

Pos: starting the pos with these keywords "Best quality, masterpiece, high res, insanely detailed" increases the output's quality slightly.

The model is incredibly obedient, being very able to literally draw nearly whatever u ask it for.

Also, despite to be not a turbo model, it's able to generate outputs in average 30s.
