Ask HN: Why are AI generated images so shiny/glossy?

I’ve noticed a lot of the time you can tell an image is AI generated because it has a shiny/glossy lighting look to it.

Has anyone figured out why this is the case?

AI is compression and compression, of any lossy kind, usually works by removing the high-frequency information first. That applies to both audio and imagery. It's obviously not the only factor, but I bet it's an important one.

Is there any technique to reapply high frequency info to make stuff look realistic?

With less lossy compression, sure. Meaning bigger models.
