Which Face Is Real: Can You Spot the AI-Generated Faces?

Could you tell the difference between an A.I. generated person vs a real person? This test will tell you how discerning your eye really is.

As someone with extensive experience as a professional photo retoucher, I've spent countless hours meticulously analyzing images at the pixel level, identifying even the tiniest flaws and seamlessly correcting them. This level of scrutiny has honed my eye to a degree that some might consider borderline obsessive or even unnecessary.

So when I first came across, I went in feeling quite confident in my ability to easily distinguish between the real and synthetic images in every single comparison. Well, it didn't take long for that confidence to be thoroughly shaken. After a few rounds on the site, I found myself starting to question my own sanity. Some of these AI-generated faces were so convincing that even my trained eye struggled to tell them apart from the real deal and admittedly did get quite a few wrong. 

It was a truly humbling experience, and it really drove home just how far this technology has come. If anyone out there claims that they were able to guess every single comparison correctly, I'd welcome them to record a video proving it. 

All in all, it was a fascinating and eye-opening moment for me. It made me wonder, what hope do regular people who aren’t trained have? It just goes to show that no matter how much of an expert you might be in a particular field, there's always room for surprises and new discoveries. And in the rapidly evolving world of AI and synthetic media, those surprises seem to be coming faster than ever before.
About Which Face Is Real

The creation of is rooted in a fundamental shift in how we perceive digital identities. In the past, we have often been skeptical of bots online, recognizing how easily words can be used to mask reality. However, images have long held a certain credibility—until now. With advances in machine learning, it has become possible to generate photorealistic images of people who don't actually exist, compromising our ability to trust even visual content.

The developers of, West and Bergstrom, aim to educate the public about the ease with which fake digital identities can be created, and to help improve our ability to spot these fakes. By presenting users with a real image alongside a synthetic one generated by “StyleGAN”, the site not only tests but also trains our ability to tell the difference between what's authentic and what's artificial.
How It Works: The Technology Behind the Site

At the heart of is StyleGAN, a type of generative adversarial network (GAN) developed by researchers at NVIDIA. First introduced in 2019, StyleGAN involves two neural networks engaged in a continuous feedback loop of creation and critique. One network generates new images, while the other evaluates them against a dataset of authentic photographs, learning from each interaction to improve the realism of its synthetic outputs.

The training data for StyleGAN came from two major sources: CELEBA-HQ, a dataset of celebrity images, and FFHQ (Flickr-Faces-HQ), a broader dataset of 70,000 facial photographs sourced from Flickr under a Creative Commons license. This extensive training enables the AI to produce highly realistic faces that can be difficult to distinguish from real ones.
Implications and Future Challenges

The implications of this technology are far-reaching and profound. Synthetic images have already been used in espionage, and as the technology continues to evolve, it's likely that they will find their way into more malicious applications. The ease with which fake profiles and identities can be created raises concerns about the spread of misinformation and fraud, making it increasingly important for individuals to become more discerning about digital content.

West and Bergstrom's initiative with is more than just a clever online game; it serves as a vital educational tool in an era where digital literacy must encompass a deep understanding of AI and its capabilities. As the technology behind synthetic image creation continues to advance, the site will remain a valuable resource for learning how to effectively spot these fakes.


In summary, serves as a compelling example of the challenges and necessities of digital literacy in the 21st century. By harnessing cutting-edge AI technology, it offers both a test and a lesson on the level of realism that synthetic identities can achieve. Moving forward, the ability to distinguish between what is real and what is artificial will become an increasingly essential skill, one that websites like play a crucial role in helping us develop.
