For best outputs:

Sampler: Euler a.

Steps: 25, cfg 7, CLIP skip 2.

VAE: kl-f8-anime2_fp16.safetensors

Pos prompt: you can keep it simple, not much weights required. Quality keywords like "masterpiece, best quality" may increase the model's quality a little.

Neg prompt: i used this one for my example runs "(worst quality, low quality:1.4), bad anatomy, disfigured, kid, child, loli, underage, 3 legs".
