A ComfyUI workflow that uses 2 models, an Illustrious one as base and a Pony model as refiner/second pass. Can easily generate UHD images (3840x2160).
All showcase images didn't use any kind of upscaling, hires fix, adetailer, etc., the latent itself was 1024x1536.
Description
Added better base promp, finer granularity for refiner pass and add metadata to image
