Really nice way to visualize the generative nature of the pictures.
They definitely look real to me. A trained eye might catch them as fake or maybe an AI app will be needed to distinguish fake from real people.
I found your comment very funny. These things are created by GANs (Generative Adversarial Networks) which work with a generator and a discriminator, which is an AI to detect fakes. So it is actually made with an AI that detects fakes.
If you zoom deeply in on the backgrounds, you may see some crosses in the background which are defects that GANs can sometimes have.
