Kasumi Arimura 有村架純: v3.0: 有村架纯1-000016.safetensors

Higher steps. May varies only a bit from v2.5.

Maybe larger (640*704) training images are not better than normal (512*512 or 512*640)... At least I tested for hours and outputs are not satifying enough.

Maybe set your resolution around 640*704 before (or without) Hires.fix would help get better results.
