You might already know that AI can put real faces in implausible scenarios, but it’s now clear that it can create faces that otherwise wouldn’t exist. Developer Phillip Wang has created a website, ThisPersonDoesNotExist, that uses AI to generate a seemingly infinite variety of fake but plausible-looking faces. His tool uses an NVIDIA-designed generative adversarial network (where algorithms square off against each other to improve the quality of results) to craft faces using a large catalog of photos as training material.

The results are imperfect (look at the area below the woman’s eyes as proof), but when everything falls into place, it’s disconcertingly realistic — you sometimes wouldn’t know a person is imaginary. It doesn’t require much computational power, either. Wang told Motherboard that he’s using an NVIDIA GPU on a rented server to create a random face every two seconds. This isn’t so much a technological breakthrough as a bid to raise awareness of AI’s ability to manipulate images.
