This is simple detailer trained on model NoobAI-XL.
V-Pred versions work better on v-pred model. If you don't know what it means - read checkpoint description. If not explicitly stated - 99% it is eps prediction version.
V-pred related specifics:
V0.5 - just slap it on with weight 1.5 makes image better.
V1.0 - slightly alters image giving more details. Weird interaction that I found - it darkens dark. V-pred NOOB-AI is first SDXL model that I see that can make really dark imagery. ESPECIALLY with short prompts, like 1girl, dark, night. If you are feeling that that is not what you want - just be more descriptive. describe face, vlothes and you won't get those black on black silhouettes anymore. Btw that applies to the NOOBvp1 itself too. See example here: https://civitai.com/images/47951726
On the upside it can darken stuff that base model has issues with darkening, like some poses.
V1.0
Merged with custom flat color lora, recommended weight is 1. Slightly alters image, especially with no prompts like 1girl.
V0.5
Weight range -6 - +6
I recommend using 1-2.
