You try to build a "true" intelligence like human, and she fills the world with false things. "There are things that don't exist," some would joke. Meanwhile, fake news and deepfakes are now everywhere.
Now the GAN, or opposing generative networks (if you want to know more I introduced them here) are used to create something that does not exist, even if it is realistic (it just lacks reality, to be precise). There are really all kinds of them: some incredible, some stupid, all certainly interesting. Here is a list of things that do not exist generated by a GAN, for a future that promises to be more likely than true.
This cat does not exist

Cats. Either you love them or you hate them. But what feeling would you have towards a cat that doesn't exist? Yet you can see so many. These cats generated by an artificial intelligence they are quite convincing, plus they don't create allergies, which can be an advantage. For the purr they are gearing up, a GAN is also needed in this sense.
This pony doesn't exist

This Pony Does Not Exist is a site that displays a colorful grid of AI-generated pony comics. The cute quadrupeds were created using Nvidia's StyleGAN2 architecture. Creatures have been created, cut out, resized and displayed in all their glory - no brush, thank you.
This machine does not exist

Here is a site that generates vehicles that never existed. All sorts of weird and wonderful cars you've never seen on the street and you'll never have. This is certainly not the best on the list, to be honest. If you refresh the page a good number of times you will start to see some really weird vehicles. More than the Dune.
These people don't exist

There is not a thing here that does not exist. There are of people who do not exist. The people you see in this collection of images do not exist and have never existed. They were created from a GAN originally developed by Nvidia, later used by Phillip Wang to create this project. The "scooter" that runs on this site essentially uses artificial intelligence to randomly generate completely artificial yet hyper realistic portraits of people. This technology is rather disturbing, because if we live in a society where images are considered evidence, a video artifact is enough to trigger violent reactions.
This meme doesn't exist (but it can exist)

Everyone loves a good meme. So why not apply artificial intelligence to create new ones? This is exactly what ImgFlip did. This meme does not exist is the result and the images generated by the system they are, well, something special.
This city does not exist

Here is a awesome website showing various aerial images of cities that don't actually exist. Yet they look like something you might find by scrolling through Google Maps or peeking out of an airplane window. Land and sea alternate with building structures. All created by un9ù
These eyes don't exist

This might sound unusual compared to the others, but it's actually quite interesting. Imagine that you are a makeup artist of some kind and need to advertise new eye makeup. Adversary generative networks allow you to create things that don't exist, say, pictures of eyes made up. This algorithm it essentially allows you to "invent" new things.
These beetles do not exist

This is a interesting project which uses machine learning to generate beetle illustrations that don't actually exist. The project was created using machine learning to analyze thousands of illustrations already in the public domain. Inspired by imagery from zoology, botany and archeology, This Beetle Does Not Exist is certainly fascinating and stands out from the rest.
These paintings don't exist

This is also delicious: it is artworks created using BigGAN (Generative Adversarial Networks) by Google, then printed and painted by Ganvas Studio. The idea is to use Joel Simon's Ganbreeder system to create your own graphics, then find it at home. Double jump: something that does not exist, but seems to exist, and in any case in the end it also becomes true and you hang it at home.
These portraits don't exist

Art Breeder it starts from the same artistic meter. It is a site that creates fake works of art with simple tweaks to the settings to change aspects of it. The results are strange, wonderful and certainly unique. These are examples of portraits that were created by this technology but would otherwise not exist. Another example? A GAN that creates Rembrandt paintings 400 years after his last work :)

This vase does not exist

Derek Philip Au, creator of This Vessel Does Not Exist, explains the logic of this project well: “The history of ceramics is a history of imitation and reproduction. The apprentice gains mastery of the trade through repetition, gradually improving his technique. Guided by a lifetime of work in the craft, the master examines each piece made by the student and throws away those deemed unsuitable. The forger also creates replicas and tests them on the market. The connoisseur, informed by decades of experience in the field of antiques, judges the replicas. Those that are mistaken for authentic are sold and the forger continues to create even more convincing copies.
