AI is a branch of computer science that aims to create machines or software that can perform tasks that normally require human intelligence, such as recognizing faces, understanding language, or generating images. One of the most advanced types of AI is called a generative adversarial network (GAN), which can create new images from scratch.
A GAN consists of two parts: a generator and a discriminator. The generator tries to create fake images that look real, while the discriminator tries to tell apart real images from fake ones. The generator and the discriminator compete with each other, improving their skills over time. The result is that the generator can produce very realistic images that can fool even human eyes.
One example of a website that uses a GAN to create fake images of people is https://www.thispersondoesnotexist.co/. This website uses a model developed by NVIDIA, a company that makes graphics cards and chips for computers. The model is trained on a large dataset of more than 70 thousand photos of real people. The model can generate new photos of people who do not exist at a high resolution of 1024x1024 pixels.
Another example of a website that uses a GAN to create fake images of models is https://www.thismodeldoesnotexist.co/. This website uses a similar model as the previous one, but trained on a different dataset of photos of models. The model can generate new photos of models who do not exist, with different poses, outfits, and backgrounds.
These websites are examples of how AI can be used to create new and realistic content that can be used for various purposes, such as entertainment, education, or research. However, they also raise some ethical and legal questions about who owns the rights to the generated images and how they can be used without harming anyone. Therefore, it is important to be aware of the source and the quality of the images that we see online and to use them responsibly.
