Probably not, since I have no idea what you're talking about. I've just been using the models that InvokeAI (2.3, I only just now saw there's a 3.0) downloads for me [0]. The SD1.5 one is as good as ever, but the SD2 model introduces artifacts on (many, but not all) faces and copyrighted characters.

EDIT: based on the other reply, I think I understand what you're suggesting, and I'll definitely take a look next time I run it.

Basically don’t use SD2.x, it’s trash and the community rejected it.

If you are using invoke, try XL.

If you want to really dial into a specific style or apply a specific LORA, use 1.5.

SDXL should be used together with a refiner. You can usually see the refiner kicking in if you have a UI that shows you the preview of intermediate steps. And it can sometimes look like the situation you describe (straining further away from your desired result).

Same goes for upscalers, of course.
