For best outputs:

Sampler: nearly any. The ones used in the example runs were Heun, Euler a, DPM++ 2M SDE Karras, DPM++ 2M Karras or DPM++ 3M SDE Exponential, among others.

Steps: 30 ~ 50, cfg around 7, CLIP skip 2.

VAE: sdxl_vae.safetensors.

Adetailer required for faces that are small (full body shots).

This is a versatile kind of model, able from realism to anime, but its strong point is that it's art oriented, being plenty trained in many art forms and artists.
