I had some trouble figuring out what exactly was going on as well, but the Stable Diffusion subreddit gave away that it was at least AI related, as that’s one of the popular AI programs. It wasn’t until I saw the tag though, that I really understood - Workflow Included. Meaning that the person included the steps they used to create the photo in question. Which means that the person in the photo was created using the AI program and is fake.

The implications of this sort of stuff are massive too. How long until people are using AI to generate incriminating evidence to get people arrested on false charges, or the opposite - creating false evidence to get away with murder.
