For best outputs:

Sampler: DPM++ SDE Karras, DPM++ SDE Karras.

Steps 4, cfg 1 ~ 1.5, CLIP skip 2.

VAE: sdxl_vae.safetensors (highly recommended).

Pos prompt: starting your prompt with "Masterpiece, extremely detailed, best quality" actually improves quality. This model also makes use of the LoRa "sdxl_offset", which improves contrast and perceived image quality. Weight to your taste.

Neg prompt: this one will do "(low quality, worst quality:1.2), lowres, multiple views, border, (grayscale, grainy), (watermark, signature, text:1.1), underexposed, overexposed, oversaturated, low saturation".

This is a semi-realistic model. It cannot create perfect realism neither anime, but instead it can create beautiful outputs quickly (feel free to check my example runs to see what it can do).
