DMD2 (Speed) Version release:

This version is a DMD2 4-step Lora merge of X-Ray V1.1. No need to download/activate the Lora separately.

DMD (Distribution Matched Distillation) allows you to generate fairly good quality images in as little as 4 steps with the LCM sampler. It cannot produce images equivalent in overall quality to a non-DMD2 checkpoint, so please keep this in mind. On the other hand, with 6-10 steps, this thing is fast as hell and outputs more than reasonable generations—which is great for anyone without a high-end graphics card.

No PAG needed for this one. Just ~8 steps, LCM w/Exponential at CFG ~1-2.0.

DMD2 Pros:

Fast, boi (i.e. ~1s with a 4090 at t2i)
Good anatomy--e.g. You can generate at 1024x1440 at t2i without anatomy horror (mostly), which might eliminate the need for additional upscaling.
Sharp

DMD2 Bad:

LCM isn’t great. Background details are a bit blurrier/painterly
Low steps means less attention to prompt and less fine detail overall
Slightly less creativity in terms of pose and composition

Suggested settings:

LCM
Exponential (or SGM-Uniform)
8-10 steps (6 also works acceptably)
CFG ~1.0-1.2
