For best outputs:

Sampler: DPM++ 2M Karras

Steps: 40, cfg 12, CLIP skip 2.

VAE: kl-f8-anime2_fp16.safetensors.

Pos prompt: always include the word "solo" unless you plan to create more than 1 single person.

Neg prompt: "more than 2 arms, easynegative, badhandv4, bad anatomy, bad hands, (low quality, worst quality:1.4), artist name, signature, watermark, choker, garter straps, legwear garter, earrings, error, mutation, mutated, fused fingers, jpeg artifacts", being "easynegative" and "badhandv4" embeddings included in the example runs.

Despite it to be an SD1.5 model, it doesn't need of great weights, but rather simple and short prompts (check the example runs).
