Version 4.0

Welcome to version 4 of my workflow, now with an even further improved base output and a different upscaling method for the refiner. I also want to give a shoutout to Bunline v0.5 and its creator yayaman for his great work finetuning PixArt!

Version 3.0

I managed to get a lot better outputs from the base PixArt Model with some changes and therefore you do not need to do as much refining anymore. Sometimes the unrefined output even seems better. I think this is a huge step up from the previous versions and I would love to hear some Feedback from you! I also wanted to thank you for all the downloads and ratings so far ❤️

Version 2.0

Updated the workflow with an optional unsampling and refining step as well as an optional upscaling step. I have also changed some default settings for the samplers.

Version 1.0

The first release of my ComfyUI workflow for PixArt with a SDXL Refiner. Custom nodes can be found with ComfyUI Manager. Read the description of each node on how to use it if you run into issues! I made this for PixArt Sigma, but the Alpha Version should work as well I think.

Follow the install instructions on https://github.com/city96/ComfyUI_ExtraModels carefully to get a proper install of PixArt and T5!
