My 2-stage (base + refiner) workflows for SDXL 1.0 in ComfyUI, with separate prompts for text encoders. If you don't need LoRA support, separate seeds, CLIP controls, or hires fix - you can just grab basic v1.0 workflow. Works with bare ComfyUI (no custom nodes needed).
SD+XL workflows are variants that can use previous generations SD models to provide initial scene concept.

* versions with fixed issue #4310.

MoonRide Mix 10 (you can replace it with any other SD variant you like).
Parameters to play with:
text in prompts,
width and height (but stick to combinations used during SDXL training - listed in notes section),
noise seeds,
steps ("end_at_step" is switching point between base and refiner - should be about 50% to 95% of total steps, depending on selected scheduler and samplers - look at preview image from base to check what is being passed to refiner stage),
scheduler,
sampler names,
cfg (lower - more creative, but also less defined),
CLIP Skip (-1 will treat prompts more literally, -3 will generalise),
LoRA strengths (0 means disabled).
Cheers, and have fun!
