nunchaku-Z-image_to_SDXL
The purpose of this workflow is to mix ZIT's excellent prompt tracking and high image quality with illustrious-SDXL's vast AGC character resources.
In other words, characters that ZIT has not yet learned can be expressed using illustrious-SDXL's learned resources without using Lora.
It combines nunchaku-Z-image-turbo 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.
