Five Telltale Signs Indicating a Photo Is AI-generated

As artificial intelligence (AI) makes it increasingly simple to generate realistic-looking images, even casual internet users should be aware that the images they are viewing may not reflect reality. But that doesn’t mean we humans are doomed to be fooled.

The process by which diffusion models—AI systems that transform text to images—learn to create images tends to generate what Matt Groh calls "artifacts and implausibilities"—that is, instances when the computer model doesn't grasp underlying reality of photographic scenes.

"These models learn to reverse noise in images and generate pixel patterns in images that match text descriptions," said Groh, an assistant professor of management and organizations at Kellogg. "But these models are never trained to learn concepts like spelling or the laws of physics or human anatomy or simple functional interactions between buttons on your shirt and straps on your backpack."
