Since I'm a lowly unwashed peasant without access to OpenAI's DALL-E 2 I've been entertaining myself with Craiyon instead.
It isn't nearly as good as DALL-E (I have friends with access, and DALL-E is too good), but it's still a tonne of fun and I've found it fairly useful as a creative tool.
If I'm not feeling particularly inventive or creative but still want to doodle I'll generate a couple of prompts for inspiration. The results are always a little wonky, but more than good enough to work with as rough concept art:
Look at those deformed goblins work! There's a lot of great little ideas to pick up from these: clothing, scenes, poses -- lots of details I probably wouldn't have thought of. It's great for doodle exercises!
Why spend time looking at reference art when an AI model has already looked at ALL the reference art?
Another excellent use case is generating horrific imagery from seemingly innocent prompts:
How is this free!?
