This workflow is intended to be used with the Z-Image Turbo model to generate an image and then refine the image using the GonzaLomo V6.0 Photo XL model. V6.0 will provide the image with much better detailed anatomical features.
Note that it's not required to use the GonzaLomo SDXL model as any photorealistic SDXL model should do a very good job at refining the Z-Image image.
The different detailers require separate models that should go in your ComfyUI /models/ultralytics/bbox folder. I've uploaded them to this model page here but you can also find these files here and here.
Description
CZXL = Chroma->ZImageTurbo->SDXL
This is a very experimental (and slow) workflow that uses Chroma to create the initial image because I think it has superior composition and color. Also, Chroma provides a wider diversity of faces and body types than ZIT, in addition to much better NSFW options.
The entire image is then passed to ZImageTurbo to be refined on a high denoise, ~0.60, because ZIT provides superior realistic textures.
Finally, there are some optional SDXL refiners to fix the naughty bits that ZIT tends to mess up.
I find that this workflow provides the best of all worlds for me but I wish it wasn't necessary. Hopefully we get much better trained ZIT models and that can take over completely. For now, this is the workflow I'm using on a regular basis.
Please provide me some feedback! I'd like to make this better and/or fix any problems that anyone discovers.
P.S. The quality of the resulting image is going to be totally defined by the different denoise settings. You can play around with the ZIT denoise a lot and go anywhere from 0.15 to 0.75. Also, the SDXL detailers have their own denoise settings that you can play with to increase/decrease the amount of detail they provide.
P.P.S I haven't added any upscaling in this initial version but I will in the next. I'm considering SeedVR2 as the upscaler.
