Ever scrolled through LinkedIn and seen a profile picture of someone who looks just a little too perfect? The lighting is studio-quality, the skin is poreless, and they’re wearing a smile that doesn't quite reach their eyes. You might be looking at one of those pics of fake people generated by a Generative Adversarial Network (GAN). It’s weird. It’s a bit eerie. Honestly, it's becoming the new normal for the internet.
We aren't just talking about filters anymore. This isn't a FaceTune edit. These people literally do not exist in the physical world. They are math. They are pixels arranged by an algorithm that has studied millions of real human faces to learn how to mimic the bridge of a nose or the way light hits a strand of hair.
Why Everyone Is Obsessed With This Person Does Not Exist
If you’ve spent any time in the tech world lately, you’ve probably heard of "This Person Does Not Exist." It’s a website created by Philip Wang back in 2019. It uses StyleGAN, a framework developed by researchers at NVIDIA. Every time you refresh the page, the site spits out a high-resolution image of a human being who has never breathed a day in their life.
It’s addictive. You keep clicking just to see if you can catch the AI making a mistake. Sometimes you do. Maybe there’s a floating earring or a ghostly blob where a shoulder should be. But mostly? Mostly, it’s terrifyingly accurate. This technology has massive implications for industries ranging from advertising to cybersecurity.
The Tech Behind the Mask
The "how" is actually pretty fascinating if you’re into neural networks. Basically, you have two AI models fighting each other. One is the "Generator." Its job is to create an image. The other is the "Discriminator." Its job is to look at that image and decide if it’s real or fake based on a training dataset.
In the beginning, the Generator is terrible. It makes grey blobs. But the Discriminator calls it out. The Generator learns. It tries again. It keeps trying millions of times until the Discriminator can no longer tell the difference between a real photo and the synthetic one.
That’s how we get pics of fake people that can fool a casual observer. It's a constant loop of trial and error at lightning speed.

The Business of Being Fake
Why would anyone actually want to use a fake person? Well, for one, it’s cheap. Stock photography is expensive. You have to pay models, photographers, and lighting techs. Then you have to worry about usage rights and royalties.
With AI-generated humans, those problems vanish.
Privacy and Protection
Some companies use synthetic faces to protect the privacy of real people. For example, if a brand is doing a case study on a sensitive topic like mental health or domestic violence, they might use a synthetic avatar. It allows for a "human" face to be attached to the story without exposing a real individual to public scrutiny.
- Marketing agencies use them to create diverse "crowds" in digital ads.
- Video game developers use them to populate background characters without needing to hand-sculpt every face.
- Researchers use them to train facial recognition software without violating the privacy of real citizens.
But there is a dark side. Obviously.
The Misinformation Machine
You've probably seen the headlines. Synthetic media is a playground for bad actors. Pics of fake people are the foundation of "sockpuppet" accounts—fake social media profiles used to spread political propaganda or run scams.
In 2019, Facebook (Meta) removed a network of accounts that used AI-generated faces to push pro-Trump content. The faces looked real at a glance, but they were used to create a false sense of grassroots support. It's called "astroturfing." It’s much more effective when the bot has a face you feel like you can trust.

Scammers on dating apps use them too. They call it catfishing, but it's catfishing on steroids. You can't reverse-image search a person who doesn't exist. There is no original source photo to find on Google Images. That makes these fake personas incredibly difficult to track.
Spotting the "AI Glitch"
So, how do you know if you're looking at a fake? Even in 2026, the AI still has "tells."
- The Background: AI often struggles with logic in the background. Look for blurred shapes that look like they belong in a Dali painting.
- Symmetry: Real faces are slightly asymmetrical. AI tends to make them a bit too balanced, or it messes up the ears. If one ear has a lobe and the other doesn't, it’s a bot.
- The Eyes: Look at the pupils. In real humans, pupils are usually circular. AI sometimes generates weird, irregular shapes inside the iris.
- Jewelry and Glasses: This is the big one. AI often fails to render glasses that sit correctly on the bridge of the nose, or it might give a person one earring that looks different from the other.
The Ethics of the Uncanny Valley
Is it ethical to use a human face for profit when that "person" can’t give consent? It’s a philosophical headache. Some argue that since the AI is trained on real people's data (often scraped from the web without permission), the resulting images are a form of digital plagiarism.
Artists and photographers are particularly worried. If a machine can generate a perfect portrait for free, what happens to the professional headshot industry?
We are also seeing the rise of "Virtual Influencers" like Lil Miquela. She has millions of followers, she does brand deals with Prada, and she doesn't exist. She’s a 3D model managed by a marketing firm. While she's clearly "fake," the line becomes blurrier when the pics of fake people look indistinguishable from your neighbor.
Real-World Examples of Synthetic Media Success
Look at a company like Synthesia. They don't just do photos; they do video. You can type in a script, and an AI avatar will "speak" it. This is used by thousands of companies for corporate training videos. It’s efficient. It’s scalable. It also means the person teaching you how to use your company’s HR software might be a ghost in the machine.

Then there is the medical field. Researchers use "synthetic patients" to share data across borders. Because the patient isn't real, there are no HIPAA violations, but the data (like X-rays or skin pathology images) is statistically identical to real human samples. That’s a massive win for science.
Navigating the Future of Digital Identity
We are moving toward a world where "seeing is believing" is a dead concept. We have to be more skeptical.
If you're managing a brand or just trying to stay safe online, you need to understand the tools. Tools like Microsoft’s Video Authenticator or various deepfake detection platforms are trying to keep up, but it’s an arms race. The fakes get better every day.
Actionable Steps for the Digital Age
Don't panic, but do be smart. Here is what you can actually do right now:
- Verify LinkedIn Profiles: If you get a suspicious DM from a stunningly attractive recruiter, check their activity. Do they have real posts? Real connections? Or just a bunch of generic "Great post!" comments?
- Use Reverse Image Search: Even though it doesn't work on pure AI faces, it catches the "lazy" fakes that are just stolen from other sites.
- Educate Your Team: If you work in marketing or HR, make sure people know that pics of fake people are a thing. Don't get caught using a synthetic face in a campaign without realizing the potential PR backlash if people find out.
- Check the Metadata: Some AI generation tools embed "watermarks" in the metadata of the file. It's not always there, but it’s worth a look.
The technology isn't going away. It's only going to get more integrated into our lives. Whether we're using fake faces to protect ourselves or to deceive others, the "human" element of the internet is changing forever. Keep your eyes open for the glitches. They’re the only thing keeping us grounded in reality right now.
