A solo developer attempted to build a version of Grand Theft Auto 6 using AI agents, but the project quickly spiraled into chaos. As reported by Wccftech, Ziwen Xu, founder of AI startup Hyperecho, began the experiment on June 10 using the Godot engine. By Day 3, the AI had implemented NPCs, cars, and environmental features. However, by Day 2, the AI agents started building the wrong city—Los Angeles instead of Miami, the real-world inspiration for Vice City.
What Happened With the AI GTA 6 Project?
Ziwen Xu’s project, dubbed GT-Caliber, aimed to explore the potential of AI in game development. The AI agents were programmed to build a version of GTA 6, but the results were unexpected. While NPCs and vehicles were added, the city layout was incorrect, and the AI continued to generate Los Angeles instead of the intended Miami setting.
The project faced additional setbacks when Xu switched to Unreal Engine 5.8 to take advantage of its Model Context Protocol. Instead of improving performance, the engine slowed the build process. “The loop runs better without it,” Xu noted, highlighting the limitations of the latest engine version in this context.
Confirmed vs. Speculative
The AI project is not affiliated with Rockstar Games or Take-Two Interactive. It is a solo experiment by Xu, and the results are not indicative of the actual GTA 6 development process. The real GTA 6 is still on track for a November 19, 2026 release, with pre-orders opening on June 25. The AI project, while fascinating, is a proof-of-concept that highlights the current limitations of AI in open-world game development.
Rockstar Games has not commented on the AI project, but Take-Two CEO Strauss Zelnick has previously stated that AI lacks the creativity needed to produce a game on par with Rockstar’s titles.
