MOSS Image picked up a cluster of community updates — step-count variants, a character reference path, a beauty pass and a style lab. Rather than treat them as separate features, this episode runs them as a matrix so the trade-offs are visible.

The six workflows

# Workflow What it isolates
01 Character reference generation Identity from a reference portrait
02 MAX ULTRA QHD High-resolution output path
04 SFT Style Lab Style transfer on the SFT variant
05 Beauty portrait Skin and feature refinement
06 Kromoss 8-step Speed/quality at 8 steps
07 StepLab 50/8/4 The same prompt at three step counts

Workflow 07 is the one worth understanding first, because it answers the question everything else depends on: what does a step actually buy you?

What step count changes, and what it does not

Running the identical prompt at 50, 8 and 4 steps:

  • Composition is decided early. All three step counts land the same layout.
  • Small text and fine pattern degrade first. At 4 steps, lettering inside the image is the first casualty.
  • Skin and fabric micro-texture is the second casualty. At 8 steps it is already smoother than 50.
  • Colour and lighting survive almost intact at 4 steps. If your image is atmospheric rather than detailed, 4 steps is genuinely usable.

That is a more useful rule than "more steps is better": spend steps on detail, not on composition, because composition is already settled.

The beauty pass is not a filter

Workflow 05 is a model pass, not a post-process. It re-renders skin with more subsurface shading and tighter feature alignment. The trade is that it also normalises — distinctive faces become slightly more generic after the pass, which is exactly what you want for stock portraits and exactly what you do not want for a specific character.
