Description
I'll probably change it to floating point for a percentage of sampling steps rather than discrete steps.done. Would recommend anyone that uses it uses it as a quicksetting.I'll look into adding an option to make NGMS skip all steps towards this end.done, this PR now fully implements the paper. Between the two options, I find I can often get away with skipping CFG on around 1/3 of total sampling steps.Screenshots/videos:
25 steps, no skipped CFG steps:
25 steps, skipped CFG on first four steps:
50 steps, no CFG skipping:
50 steps, skipped CFG on first eight steps:
As you can see, the image with CFG skipping converged much faster. There are some noticeable side effects on image brightness (prompt on this image contained
(dark,:1.3)
, so this is somewhat less dark than I would typically expect).Checklist:
