That looks interesting, but I don't know how useful single icons can be. For me, the really useful part would be to get a suite of icons that all have a consistent visual style. Bonus points if I can prompt the model to generate more icons with that same style.

Recraft has a style feature where you give some images. I wonder if that would work for icons. You can also try giving an image of a bunch of icons to ChatGPT and have it generate more, then vectorize them.
