# This Site Tests Whether You Can Spot AI-Generated Faces

## A/B Testing

Deepfakes and other AI-generated images have become commonplace the algorithms that churn them out have become widespread.

On one sugar-coated hand, this means [cooler movie](<https://futurism.com/artificial-intelligence-automating-hollywood-art>) and [video game visual effects](<https://futurism.com/ai-dreams-trippy-video-games-based-real-life>). On the other hand, it means that bad actors can produce [photorealistic propaganda](<https://www.theguardian.com/technology/2018/nov/12/deep-fakes-fake-news-truth>), [fake porn of real people](<https://www.vice.com/en_us/article/j5kk9d/deepfakes-were-created-as-a-way-to-own-womens-bodieswe-cant-forget-that-v25n2>), or other convincing but fake media.

That's why two University of Washington scientists created a website, "[WhichFaceIsReal.com](<http://www.whichfaceisreal.com/about.html>)," which is meant to train people to spot the telltale signs that an alleged photo was actually built by an algorithm — by asking them to guess which of two side-by-side photos a real person and which is an AI-created dupe.

## Facial Recognition

The website has been up and running since February, shortly after a website called "[ThisPersonDoesNotExist.com](<https://thispersondoesnotexist.com/>)" went live.

That site highlights an AI algorithm built by Nvidia called StyleGAN that can create [almost-perfect portraits](<https://futurism.com/mysterious-site-ai-realistic-horrifying-faces>) of human faces out of thin air.

WhichFaceIsReal focuses on the specific errors and glitches in StyleGAN portraits, so the [tips and tricks](<http://www.whichfaceisreal.com/learn.html>) — look for asymmetrical glasses, ears, and jewelry; check whether the background is full of mysterious splotches of color — don't always generalize to other face-generating AI algorithms.

But if nothing else, WhichFaceIsReal can serve as a reminder that [AI-generated media](<https://futurism.com/ai-generates-entire-bodies-people-dont-exist>) is coming soon, and we're all going to have to be more critical about the images and videos we see every day.
