This is a modified default workflow that lets ComfyUI generate picture again and again until BLIP says conditions are met. You can set conditions in a natural language like:
What is this face expression?
Is this a classical art?
Is she completely naked?
Installation
Install WAS Node Suite custom nodes;
Install Cyclist custom nodes;
Download and open this workflow.
How to use
Select model and prompts;
Set your questions and answers;
Check Extra Options and Auto Queue checkboxes in ComfyUI floating menu;
Press Queue Prompt;
After success, check Auto Queue checkbox again.
Notes
BLIP is not human. Its answers are not 100% correct.
Answers may come in specific form, like "1" or "one". Check your console to see every BLIP answer.
You can replace BLIP with Aesthetic Score or Image Reward (Aesthetic + BLIP), but the problem is they're just not very good.
