@The Prompt Challenge

Great way to improve you prompting skills through daily exercises. This should be implemented in schools, would really help students. Can also see it being really valuable for adults. Not just for prompting, but for articulation in general. Also made a video about it: https://www.youtube.com/watch?v=A8ZRJgLCFy8

Diffusion pulls out extremely good images from simple prompts. Renders were a little slow on higher quality, but totally worth it for the results. The controls feel clear enough and the outputs look legit. Good one here!
