I would love to see the table of racial categorizations and probabilities. I doubt the probabilities match those of world demographics - with the American categories I and many readers are familiar with, I bet they have "White" and "Black" overweight, "East Asian" and "South Asian" underweight.

That's what it does yes. If you ask it for an image with a programmer in it for example, the prompt it feeds to DALL-E (which you can see) will explicitly request a female programmer.
