Amazing work! If I had a GPU, I'd join. I know similar project for text-to-image: https://aqualxx.github.io/stable-ui/
My only problem with stable horde is that their anti-cp measure involves checking the prompt for words like small, meaning I can't use a nsfw-capable model with certain prompts (holding a very small bag, etc). That, and seeing great things in the image rating and being unable to reproduce because it doesn't provide the prompt.
