"This X Does Not Exist" is a collection of websites that showcases realistic but fictional content created using generative models such as generative adversarial networks (GANs). The homepage introduction states that with GANs, we can learn how to generate realistic-looking fake versions of almost anything; this collection brings together a batch of such websites that emerged over the past month.
Purpose: The website itself is an index-style collection used to display and summarize various "does not exist" generator websites. It does not directly generate content, but instead provides links to or descriptions of multiple independent sites, allowing visitors to learn about the application of generative models to different objects.
Main capabilities and covered topics: The collection covers a wide range, including faces (thispersondoesnotexist.com, using StyleGAN), cats, interior design, plot summaries, Stack Overflow questions, resumes, facial emotion recognition, ceramics, lyrics, food, memes, chairs (3D and with adjustable "weirdness"), SMS chatbots sending foot animation images, art styles, chemical molecules (3D models with correct bonding), horses, nonexistent words (using GPT-2), UK Parliament faces, ponies (pan and zoom), Cybertruck inspiration sources, cosmetics, butterflies, aerial views of airplanes, recipes, Simpsons style, fursonas, night skies, music videos (combining OpenAI Jukebox and StyleGAN), beaches, maps, startup ideas, sneakers, baseball players, flags, interview Q&A, irises, sounds, Pepe, houses, natural landscapes, mountains, musical scores, GeoGuessr-style street views (DALL-E 2), doodles, airports, theatrical stages, and more.
How to use: Most sites generate new content by refreshing the page; some sites offer interactive features, such as generated chairs with adjustable "weirdness," ponies that can be panned and zoomed, chemical molecules rendered as 3D models, maps where you can create details yourself, street view games that can be played, music videos that can be watched, and so on. The collection homepage provides brief descriptions of each site, guiding users to visit the corresponding websites.
Applicable scenarios: Suitable for users interested in generative adversarial networks, applications of generative models, and AI creative content to browse and experience; it can also be used to understand the generation effects and limitations of GANs across different modalities such as images, text, and audio.
Limitations: The homepage explicitly states that some generated content may show visual deformities due to imperfect models, for example cats may occasionally have visual defects, which may cause discomfort. Some sites use technologies that are not strictly GANs, for example the resume website uses TextgenRNN (a type of recurrent neural network), word generation uses GPT-2, the street view game uses DALL-E 2, and the emotion recognition website does not use deep learning. In addition, some content such as drug discovery, political figures, and the music industry is for display purposes only and should not be regarded as real, usable professional tools; some sites may contain adult or discomforting content (for example, the Simpsons-style site is described as "very dark," and the SMS chatbot involves foot images), so visitors should use their own judgment.
