This Person Does Not Exist

This Person Does Not Exist is an intriguing AI-powered tool that generates random human faces with remarkable realism. With just one click, users can witness the creation of a non-existent person's face and have the option to download it. The generator is based on StyleGAN, a neural network from Nvidia developed in 2018. This technology consists of two competing neural networks, one that generates content and another that attempts to determine its authenticity. The training process continues until the generating network can consistently deceive the other.Interestingly, the creation of non-existent people's photographs was initially a by-product; the main goal was to train the AI to recognize fake and real faces to improve the performance of Nvidia's video cards. For users, the process is straightforward. Upon accessing the website, a random face is instantly generated. If the user is not satisfied with the result, they can simply refresh the page to get a new face. The website showcases the generator's output, which is updated every 2 - 3 seconds. However, recognizing a fake person's image is an extremely challenging task. AI has advanced to the point where 90% of fakes go undetected by the average person, and even 50% elude experienced photographers. Currently, there are no dedicated services for recognition, but occasionally, neural networks make mistakes, resulting in artifacts such as incorrect patterns, strange hair colors, and more. To detect forgeries, one needs to closely examine the image, as humans' visual processing systems are more powerful than computers in this regard. For example, look for symmetrical issues like uneven eyeglasses or earrings, as well as odd characteristics like pixels and repeated incisors. Fake hair may appear with a certain glow or an overly straight and streaked look, along with visible asymmetry. Carefully studying the background for unusual distortions or a torn appearance can also be helpful. Additionally, the NVIDIA 'StyleGAN algorithm' sometimes produces glossy 'water splotches', which can be a distinguishing feature. Overall, This Person Does Not Exist demonstrates the incredible capabilities of AI in generating realistic images, while also raising questions about the potential implications of such technology.
