Hey! Creator of ArtBot here. Thanks for plugging the site!
For those not aware, here's an interesting fact about ArtBot (and the AI Horde in general) -- we've been running an A/B test with Stability.ai for the last 3 weeks or so related to SDXL [1].
Any time a user generates an image using SDXL_beta on the AI Horde, they get two images back. They pick which image they think is best for the given prompt. This data is sent back to Stability.ai in order to help improve their image models.
In a similar vein, LAION partnered with the AI Horde earlier this year in order to gather aesthetics ratings for improving various image datasets. [2]
It's a cool little open source community and there's just a ton of stuff going on.
I just took the ones I liked and then deleted out the words that were specific to that image and left the ones that were providing the style of the image. So for example on the first one I would delete "an cute kitsune in florest" but would keep "colorfully fantast concept art". Then I just added a comma separated list of the of the features I wanted in my picture. It took a lot more trial and error than I thought and adding sentences seemed to be worse than just individual words. I am sure I barely scratched the surface of interfacing with the tool correctly but the space is moving so fast its not the kind of thing I want to spend my time learning right now just to have that knowledge deprecate in 6 months.
