RobMix - Evolution V2.0
by ModelsLabRobMix Evolution builds on my first merge, RobMix Ultimate.
This version starts with RobMix Ultimate, then merged block-by-block with some fantastic models to draw out the best parts of each and mitigate the downsides. My goal was to expand the creative range of the model while retaining the photorealistic style.
You can read my process for early experiments with Evolution on Medium. Note that the models referenced in the post went into a personal merge that I called Evolution A and Evolution B—the models referenced in that post aren't included in Evolution D.
The final stage of Evolution, Evolution D, started by blending:
Photonium for photorealism
That blend was merged back into RobMix Ultimate.
Next, I added a block-by-block merge of Juggernaut v9, followed by a dash of ICBINP XL v4.
This model can be sensitive to high CFGs.
Recommended settings:
DPM++ 3M SDE
AlignYourSteps scheduler
CFG 3.0-4.0
40 steps
Clip Skip -3
The higher the CFG, the more steps you'll need. If it's speed you're looking for, you may want to look elsewhere. Alternatively, consider using the genius Automatic CFG node in Comfy and set your CFG wherever you'd like.
This model is generally very capable with only a single pass, but really shines in quality with a 1.5x latent upscale at 0.30 to 0.40 denoise with an additional 40 steps.
With this full workflow, a generation on my 3080 takes around 40 seconds.
To get the very best results, add the following optimizations:

b1: 1.05
b2: 1.08
