Dalle seems to only have a few "styles" of drawing that it is actually "good" at. It is particularly strong at these styles but disappointingly underwhelming at anything else, and will actively fight you and morph your prompt into one of these styles even when given an inpainting example of exactly what you want.
It's great at photorealistic images like this: https://labs.openai.com/s/0MFuSC1AsZcwaafD3r0nuJTT, but it's intentionally lobotomized to be bad at faces, and often has an uncanny valley feel in general, like this: https://labs.openai.com/s/t1iBu9G6vRqkx5KLBGnIQDrp (never mind that it's also lobotomized to be unable to recognize characters in general). It's basically as close to perfect as an AI can be at generating dogs and cats though, but anything else will be "off" in some meaningful ways.
It has a particular sort of blurry, amateur oil painting digital art style it often tries to use for any colorful drawings, like this: https://labs.openai.com/s/EYsKUFR5GvooTSP5VjDuvii2 or this: https://labs.openai.com/s/xBAJm1J8hjidvnhjEosesMZL . You can see the exact problem in the second one with inpainting: it utterly fails at the "clean" digital art style, or drawing anything with any level of fine detail, or matching any sort of vector art or line art (e.g. anime/manga style) without loads of ugly, distracting visual artifacts. Even Craiyon and DALLE-mini outperform it on this. I've tried over 100 prompts to get stuff like that to generate and have not had a single prompt that is able to generate anything even remotely good in that style yet. It seems almost like it has a "resolution" of detail for non-photographic images, and any detail below a certain resolution just becomes a blobby, grainy brush stroke, e.g. this one: https://labs.openai.com/s/jtvRjiIZRsAU1ukofUvHiFhX , the "fairies" become vague colored blobs here. It can generate some pretty ok art in very specific styles, e.g. classical landscape paintings: https://labs.openai.com/s/6rY7AF7fWPb5wWiSH0rAG0Rm , but for anything other than this generic style it disappoints hard.
The other style it is ok at is garish corporate clip art, which is unremarkable and there's already more than enough clip art out there for the next 1000 years of our collective needs -- it is nevertheless somewhat annoying when it occasionally wastes a prompt generating that crap because you weren't specific that you wanted "good" images of the thing you were asking for.
The more I use DALLE-2 the more I just get depressed at how much wasted potential it has. It's incredibly obvious they trimmed a huge amount of quality data and sources from their databases for "safety" reasons, and this had huge effects on the actual quality of the outputs in all but the most mundane of prompts. I've got a bunch more examples of trying to get it to generate the kind of art I want (cute anime art, is that too much to ask for?) and watching it fail utterly every single time. The saddest part is when you can see it's got some incredible glimpse of inspiration or creative genius, but just doesn't have the ability to actually follow through with it.
