Google's internal models (Imagen and Parti) are much better. It looks like DALLE2 is just not big enough to accurately draw faces, which are very detailed things.

"This person doesn't exist" uses StyleGAN which can definitely do faces, but can't do general pictures.

Are there samples of faces by the Google models? The websites don't seem to show any. Though their 20B samples are incredibly impressive.

There's animal faces. Google employees have been tweeting a lot more image samples, though I don't remember if any have human faces.

(Its output seems to be a lot more aligned to the input than DALL-E2, but also less "artistic" and more like it just did exactly what you said.)
