Which Face is Real?

One service creates them while the other tests your ability to detect an AI forgery.

I was out and about on the internet, snooping for a free API to use for a little project I wanted to work on when I remembered This Person Does Not Exist.

"Hmm," I thought to myself. "I wonder if I could make a fake product review app with these fake faces?"

But before I could get to that, a second thought struck me. "Can people reliably tell the difference between a forgery and reality regarding human photos?"

And that was a trickier problem to get to the bottom of. Some estimates put humans' inability to detect a faked face as high as 90%.

Now, I've seen a lot of faked images in my day, and I feel like I have a pretty good grasp of what fakes look like. Some are virtually impossible to tell from real faces. Still, the vast majority typically have some "stitching" issue—where a pattern is broken or a mismatch occurs regarding facial symmetry.

So I looked up what kind of websites there are that test this, and lo, I found Which Face Is Real.

This is a distraction you didn't know you needed. Make a little game out of it so that when Skynet shows up, you'll be ready to spot fake photos that have no relation whatsoever to Terminators.
