Version 9: should work with most samplers. I dent to use CFG 4-5 and 30 steps. Sometimes the pony triggers can be helpful like score_9, ...
DMD2 versions: quite fun and super fast LCM Karras or Normal CFG 1.2-1.5, 4-8 steps You can use slightly higher CFG like (8 steps or more). Hires. fix I usually use 4 steps.
Version 4: Works with DPM++ SDE starting 6 steps but 9 is better (6 is a bit soft) and cfg 3 - 3.5 Works with other sampler too but did not test those much yet. They seem ok and work at fairly low steps too.
V3 is a complete rework, all samplers are usable. I am not sure what is going on model hash is the same but I seem not to be able to recreate the same pictures. I don't know if the windows update or Nvidia update messed something up for me.
V2 was made to be used with DPM++ 2M SDE (karras or exponential), some others should work too. 3M SDE and 2S a seem to work well too. Steps 12-16 works fairly well. You can push CFG fairly high to like 12 but might depends on steps.
As an experiment merges some lightning and others and 3 of my Loras.
Quite like it so I thought I would share.
DPM++ SDE Karras starting 6 steps and CFG 2 works (not sure if there is limit 20 steps cfg 5 works too for example).
