Great document. Damn I am salivating to get access to Dall-E for some projects. Been on the waiting list for quite a while. I've been experimenting with Midjourney, which is amazing for spooky/ethereal artwork, but it struggles with complex prompts and realism.
Hang in there — I only got my invitation a couple days ago. They're still rolling out invitations at a steady pace. But, just as a side note, one of the first things they tell you is that they own the full copyright for any images you generate. You definitely have to play around with prompts to get a feel for how it works and to maximize the chance of getting something closer to what you want.
When did you sign up? I just signed up, and it sounds like it takes a year to get access, probably longer now. It's a bit frustrating because I didn't sign up when it came out because I didn't need it at the time, but now I'm afraid of waiting a year when I do. These types of waitlist systems encourage everybody to sign up for everything on the off-chance that they might need it later. Wish they just went with a simple pay-as-you-go model (with free access for researchers and other special cases who request it), like how Copilot does it.
