V4: the usual cfg1, 8-10 steps usually, not picky about samplers works with euler, lcm, sde samplers. Q4KM works, however more sensitive to banding sometimes, if you have the Vram use the Q8.

V3: similar as V2 but work usually with 8 steps and cfg 1.

V2: use Euler or Lcm with simple, beta at 10-12 steps, I tend to use cfg 1.3

A bit of an expirment to se how it goes and get a bit more face variation than the normal Qwen.
