You've probably seen that one face. It looks like a friendly neighbor, maybe a barista or a college student with slightly messy hair. The lighting is perfect. The pores are visible. But that person has never breathed a day in their life. They are images of fake people, generated by math and massive datasets, and they are everywhere now.
It started as a parlor trick. Back in 2014, Ian Goodfellow and his colleagues introduced Generative Adversarial Networks (GANs). It was a breakthrough. Essentially, you have two AI models: one tries to create a fake image, and the other tries to spot the fraud. They duel until the "creator" gets so good the "judge" can't tell the difference anymore. Fast forward a decade, and we aren't just looking at blurry thumbnails. We are looking at high-resolution, photorealistic humans that can trick even the most skeptical eye.
How Images of Fake People Actually Work
Honestly, it’s kinda terrifying how simple the concept is compared to the result. Most of the realistic faces you see today, like those on the famous site "This Person Does Not Exist," are built on a style-based generator architecture called StyleGAN, developed by researchers at NVIDIA.
It doesn't "think."
It predicts.
The AI looks at millions of real human photos. It breaks them down into features: the distance between eyes, the texture of a cheekbone, the way light hits a forehead. When you ask it for a new face, it’s basically remixing those learned patterns into a new configuration. It’s like a digital chef using ingredients from ten thousand different kitchens to bake a cake that looks familiar but has a completely unique recipe.
The complexity is staggering. We’re talking about mapping latent space—a multi-dimensional mathematical realm where every point represents a different facial feature. If you move a tiny bit to the left in this "space," the eyes might turn blue. Move up, and the person gets older.
Why the "Uncanny Valley" Is Disappearing
We used to be able to spot these easily. There were "tells." Maybe the earrings didn't match, or the hair looked like it was melting into the background. Sometimes the teeth were just a solid white block. But as models like Midjourney v6 and Stable Diffusion XL hit the scene, those glitches started vanishing.
The "uncanny valley" is that creepy feeling you get when something looks almost human but not quite. It’s a survival instinct. Our brains are wired to detect "wrongness" in faces to avoid disease or danger. But modern images of fake people are bridging that gap. They’ve mastered the imperfections. They add "skin noise"—tiny moles, slight redness, or uneven skin tones—that make them look more real than a heavily photoshopped celebrity on a magazine cover.
The Business of Being Fake
Why would anyone want a fake person?
Money.
Stock photography is expensive. If you’re a startup and you need a "diverse group of professionals" for your landing page, you have two choices. You can hire a photographer, rent a studio, and pay five models. Or, you can subscribe to a service like Generated Photos for a few bucks and get 10,000 unique faces that you never have to pay royalties for. No contracts. No expiration dates. No human drama.
It’s a massive shift in the creator economy. We’re seeing "AI influencers" like Lil Miquela or Aitana Lopez. These aren't just images; they are brands. Aitana, for instance, reportedly earns thousands of dollars a month in sponsorships. Brands love it because a fake person never gets "canceled" for a controversial tweet from 2012. They are perfectly controllable.
But there’s a darker side to the business.
Identity Theft and the Rise of "Ghost" Profiles
Scammers are obsessed with images of fake people.
Think about catfishing. In the old days, a scammer had to steal a real person's photos from Instagram. If the victim was smart, they’d do a reverse image search and find the original owner. With AI-generated faces, there is no original owner. The reverse image search comes up empty. It creates a "clean" identity that looks perfectly legitimate to a dating app or a LinkedIn recruiter.
Security experts like Hany Farid, a professor at UC Berkeley and a pioneer in digital forensics, have been sounding the alarm for years. These images are being used to create massive networks of "bot" accounts that look like real citizens. They spread misinformation, manipulate stock prices, or just harass people. When the face looks like a real human, we are naturally more inclined to trust what they say. It’s a psychological hack.
Spotting the Glitches in 2026
Even with the tech getting better, you can still catch them if you know where to look. It’s sort of like being a digital detective.
- The Eyes: Look at the reflections (specular highlights). In a real photo, the reflection of the light source in the pupils should be identical in shape and position. AI often struggles with the physics of light, creating slightly different reflections in each eye.
- The Background: AI puts all its "brain power" into the face. The background often becomes a surrealist nightmare of warped lines, floating shapes, or textures that don't make sense.
- The Ears and Jewelry: Ears are incredibly complex. AI frequently makes them asymmetrical or forgets where the lobe ends. Similarly, earrings might not match, or a necklace might disappear into the skin.
- The Hair-to-Skin Transition: Look closely at the hairline. Real hair has individual strands that overlap the forehead in a specific way. AI often blurs this transition, making it look like the hair is growing out of a smudge.
The Ethical Quagmire
We have to talk about the data. Where did these millions of "real" faces come from? Mostly, they were scraped from the internet without the explicit consent of the people in the photos. The FFHQ (Flickr-Faces-HQ) dataset, which powered much of the early GAN research, was pulled from Flickr.
Is it okay to use your face to teach a machine how to replace you?
That's the question regulators are currently fighting over. The European Union's AI Act is one of the first major attempts to put guardrails around this, requiring disclosure when an image is AI-generated. But the internet is borderless. A "fake person" created in a basement in one country can influence an election in another.
There's also the "Liar’s Dividend." This is a term coined by legal scholars Danielle Citron and Robert Chesney. It basically means that because we know images of fake people exist, real people can claim that genuine, incriminating photos of them are "just AI fakes." It erodes our collective sense of what is true.
Practical Steps for Navigating a Synthetic World
You can't hide from this technology, so you might as well get smart about it. Whether you're a business owner or just someone browsing social media, here’s how to handle the rise of synthetic humans.

Verify Before You Trust
If you encounter a profile that seems a little too perfect, use a tool like "Maybe's AI Detector" or look for the "Artifacts" mentioned earlier. If it’s a business contact, ask for a quick video call. AI video is catching up, but it still struggles with real-time, unscripted interaction.
Use AI Images Responsibly
If you’re a creator using these images, be transparent. Many platforms now have tags for "AI-generated content." Using these isn't just about being "nice"—it’s about building long-term trust with your audience. People don't mind the tech; they mind being lied to.
Understand the Licensing
If you use a service to generate fake people for your business, read the fine print. Some licenses allow commercial use, while others don't. And remember: you cannot currently copyright an image generated entirely by AI in the United States. This means competitors could technically "steal" your AI mascot and you might have limited legal recourse.
Watch the Hands
It’s a cliché for a reason. AI still hates drawing hands. If a "person" in a photo has their hands tucked in their pockets or hidden behind their back, be suspicious. If you do see fingers, count them. Six fingers is still a surprisingly common AI hallucination.
The world is filling up with people who don't exist. It’s a strange, fascinating, and slightly uncomfortable reality. But by understanding the mechanics behind these images and staying skeptical of "perfect" digital faces, you can navigate this synthetic landscape without losing your grip on what's real.
