A simple 3-image Klein 9B edit workflow for ComfyUI. This workflow is built for combining multiple image references into one edited output using a prompt-driven FLUX/Klein setup. Drop in three source images, describe how you want them combined, and let the workflow handle the reference conditioning, edit pass, detail refinement, upscaling, and final sharpening.
The setup uses reference latents from all three input images, a two-stage sampling flow, Detail Daemon refinement, Remacri upscaling, resize to 1920px longest side, and CAS sharpening for a cleaner final image.
Good for quick composites, character/object placement, car edits, scene edits, and testing multi-image reference control without building a huge complicated workflow from scratch.
This is a basic V1 workflow, so treat it as a starting point and tweak CFG, denoise, steps, sampler, and prompt strength depending on your images. This workflow uses res2 sampling.

Anyone using UmeAirt getting a crash as soon as this flow hits Sampler 1? I have tried a couple of up to date fresh installs and no joy getting this workflow to get past that point.
Whats UmeAirt? It's made for comfyui.
It's a Comfy auto installer. As soon as this workflow hits Sampler 1 on this Comfy build it crashes Comfy and will not relaunch until all the workflow process is purged. I have tried a couple of clean installs and still no luck.
I doubt it is hardware related as my system is pretty beefy by home machine standards. 14900k, 192gb 6000, liquid cooled 5090. Not showing off just got really lucky on the GPU and memory, bought right as GPU's dipped and days before memory went nuts. Swap file etc all set up to push some pretty heavy LTX 2.3 loads.

@markfjohnson You’re probably missing the res2 sampler https://github.com/ClownsharkBatwing/RES4LYF
@EchoSingularity I already had the RES4LYF nodes installed. Reinstalled the latest package just in case but no luck.
@EchoSingularity Seems there was a conflict between logicutils and sage attention in my comfy build. Bypassing the sage attention nodes allows the workflow to go to completion. Certainly not an expert but as I understand it I may or may not lose a little speed with that bypass but otherwise no harm done?
@markfjohnson Yeah you're fine running without sage attention. You can always try changing the node to use a different version and that might work. Without it you'll just lose some speed but not a big deal.
It works but the generated image looks cartoony as hell and not good tbh.
