and here is a fixed version of their NAG chroma workflow. this is a good basis for testing various settings and comparing to your old chroma workflow.

I suspect NAG makes chroma work better with lower CFG values like around 3. But NAG doesn't replace CFG, you still need CFG enabled unless you are using DMD2/turbo/etc.

I'll also post comparisons VS NegPip for SDXL, as I already replaced negative prompts and CFG completely with NegPip in my SDXL workflows.
