Model description
flux2_klein-SDXL_Upscale_workflow
(text to image upscale)
The purpose of this workflow is to mix flux2_klein excellent prompt tracking and high image quality with illustrious-SDXL's vast AGC character resources.
In other words, characters that flux2_klein has not yet learned can be expressed using illustrious-SDXL's learned resources without using Lora.
It combines flux2_klein and SDXL for extremely fast generation speeds.
This is how I use it, but it's up to you to use it in your own way.
* Note *
Turn Off Upscale-Switch, only flux2_klein will be rendered.
Can be used as a regular flux2_klein workflow
