For best outputs:

Sampler: Euler a / DPM++ 2M Karras.

Steps: 30, cfg 8, CLIP skip 2.

VAE: none required.

Pos prompt: the model is NSFW, which means, it is great at making nudes, even at making girls take sensual / seductive positions easily, but it can not make sex / porn on its own. For this, you will need the help of LoRa's.

Neg prompt: anime, cartoon, 3d render, child, old, overexposed, underexposed, monochrome, watermark

What changes from v3.0 to v4.0: input_image feature.

Checkpoint Merge.
