For best outputs:

Sampler: DPM++ 2M SDE Karras mainly

Steps: 60 ~ 80, cfg 4 ~ 8, CLIP skip 1

VAE: this model has its own VAE -> sdxl_vae.safetensors

The prompts: this model does not actually need too complicated prompts (do so if u please tho); the neg prompt must be pretty elaborate (or not) depending on your needs. This model can actually achieve incredible results with poor prompts anyways.
