This here is a basic workflow for Colossus XL 4.9 and the experimental version Colossus Project XL 4.9b Experimental
This workflow saves two pictures but you can delete the third stage if you want.
There are two versions.. try both.
The Colossus Project XL workflow is compatible with every Colossus Project XL model and DEMON CORE
The 4.9 experimental workflow can might work with the other versions but was made for the Experimental model.
I highly recommend to install the Comfy Manager before because this workflow needs costom nodes. Here is the link. https://github.com/ltdrdata/ComfyUI-Manager
