For best outputs:

Sampler: DPM++ SDE.

Steps: 8, cfg 2, CLIP skip 1.

VAE: none required.

Pos prompt: quality keywords may increase overall quality a little. This model tends to understand the word "breasts" as "nipples", so if you don't want NSFW, add SFW to the pos and NSFW to the neg.

Neg prompt: can be left blank, but the "photograph" keyword gives the outputs a nice result.

This model produces high quality digital art.
