NVIDIA’s mind-blowing AI that generates faces of people who don’t exist recently led to an unofficial website called thispersondoesnotexist.com that lets anyone generate a new random face in an instant.

The former Uber-software engineer says that since its launch, This Person Does Not Exist has been visited about 4.2 million times, not bad for a one-off site originally posted to a closed Facebook Group. Wang initially used it as a way to convince a few friends to join in on the independent A.I. research he’s currently working on.

Follow the steps below to generate faces of people that do not exist using Unrealperson.com: Step 1: Use any good internet browser to visit the website on your mobile phone or computer. Step 2: Select the category of the subject you want to generate: People, Cat, Horse, Art, and Beach. Click “Generate” and wait a few seconds.
