Grand Theft Auto VI is finally set to come out this November, after being in development for roughly a decade. For many fans, the wait has felt even longer considering Grand Theft Auto V first came out in 2013. Now, one AI startup founder apparently can\u2019t wait any longer, so he\u2019s trying to vibe code his own version. \u201cDay 1 of building GTA 6. Still feels fake typing that out,\u201d wrote 25-year-old Ziwen Xu on X this Wednesday. \u201cUpgraded to Claude Max 20x just for this. Spent a couple hours getting the whole project structured and pushed to the repo.\u201d The post included a short clip of the game, which on day one mostly consisted of a 3D blue oval moving and jumping around some gray blocks. Xu seems to be pretty sincere about the effort. He has been posting updates every day since the original post and has even shared the code repository on GitHub. Still, it does make you wonder how much time this project is taking away from his day job as the founder of Hyperecho, a startup that helps companies deploy \u201cAI employees.\u201d<\/p>\n
\u201cThe goal: beat the real GTA 6 to launch. Ambitious, probably stupid, doing it anyway,\u201d wrote Xu. The project appears to have been inspired by a post from another AI startup founder and investor.<\/p>\n
\u201cSomeone should set up a community-funded Fable run with a prompt like: \u2018\/loop until you\u2019ve created a GTA-VI-caliber open-world game with a quality and scope surpassing what is shown in the initial trailers,\u2019\u201d wrote Matt Shumer in a post reposted by Xu. Basically, the idea is to see whether Anthropic\u2019s Claude Fable 5, a safer public version of the company\u2019s more advanced Mythos model, could vibe code a GTA-caliber video game. Vibe coding is a relatively new approach where developers rely heavily on AI assistants to generate and debug code using natural language prompts.<\/p>\n
Some high-profile tech founders are fond of the approach. Jack Dorsey vibe coded at least two apps last year. Meanwhile, OpenAI cofounder Andrej Karpathy, who coined the term, has said that using AI agents is \u201cnet unhelpful.\u201d Still, on day two Xu posted a video showing a much more human-looking character running around an urban landscape, though he admitted it was still far from perfect. \u201cThe agent built downtown LA skyscrapers, which is a problem, because this is supposed to be Florida,\u201d Xu wrote. \u201cAlso I\u2019ve burned 33% of my 20x weekly usage in one day. So that clock is ticking.\u201d By today\u2019s update, the game included NPCs walking around, cars driving on roads, and even weapons.<\/p>\n
