This new merge checkpoint is a variant of Popwind (see resources) with greyscale filter. It could bring good results for highly detailed pictures in anime style. Note that it sometimes brings back color if you ask for it (ex : yellow hair).

I'd recommend so far :

• 1024x1024 at least (consider adding Hi-Res).

• CFG 4-5

• DPM++ 2M or Euler a

• Sampling steps 25-30
