Modder Uses AI to Run Minecraft Inside GTA V on iPhone via C22 Port
A developer used Claude Opus 5.5 to integrate Minecraft into a native iOS port of Grand Theft Auto V, demonstrating advanced AI coding capabilities on mobile hardware.
Key points
- Modder 0xProbability used AI to embed Minecraft into C22's native iOS port of GTA V.
- The port runs on iOS 15+ and macOS 14+ Apple silicon, achieving 50-60 FPS on iPhone 17.
- Claude Opus 5.5 wrote and tested the code, with the modder not touching the phone during the demo.
Modder 0xProbability successfully launched Minecraft inside a modified version of Grand Theft Auto V running natively on an iPhone. According to Tom's Hardware, the developer used Anthropic’s Claude Opus 5.5 to write the code and test the game, with the modder claiming they did not touch the phone while the AI flew the Ender Dragon around Los Santos.
The demonstration showed the Minecraft heads-up display and the character Steve loading directly within the GTA V environment. The AI handled the process of coding and testing, as 0xProbability stated they did not interact with the device during the flight sequence. This event highlights the capability of large language models to perform software development and testing tasks, with the user observing the results without manual intervention on the hardware.

Technical Context of the Port
The underlying GTA V port was created by C22, a student at the École Polytechnique Fédérale de Lausanne in Switzerland. C22 adapted a browser-based version of GTA V to run as a native iOS application, enabling features like multiplayer support. The README for the port specifies compatibility with iOS 15 or later and macOS 14 or later on Apple silicon devices.
According to C22’s video on X, the port runs at 50 to 60 frames per second on an iPhone 17 while consuming only 1.1GB of RAM. The project ideally requires devices with 8GB of RAM or more for optimal performance. This technical achievement allows a heavy 3D game to operate smoothly on mobile hardware that previously could not natively support such titles.
AI Role in Development
Before deploying the mod to the iPhone, 0xProbability experimented with the browser version of GTA V, adding block-building mechanics and Minecraft mobs. The developer noted that web browsers have evolved from hosting simple .io games to running heavy 3D applications in 2026. The use of Claude Opus 5.5 allowed for the writing and testing of these complex modifications.
The integration process involved the AI model generating the code and testing it, with the modder not touching the phone during the demonstration. This approach showed how much Claude Opus 5.5 is able to write code and test it on its own. It demonstrates a shift in how software modifications can be developed using advanced generative AI tools, with the user relying on the AI for execution.
What should you do?
Security professionals should monitor for unauthorized code execution in native applications, especially those derived from web technologies. Users running modified games should be aware of the potential security risks associated with unvetted code. Developers should review their app sandboxing strategies to prevent similar integrations.
Background: Large language models
Large language models are a specific type of neural network trained on text. Generative AI is the broader umbrella term for any system that creates new content, including images and code. Not all generative AI uses large language models, but most modern text generators do.
What to do and how to stay safe: GTA V
- Review application permissions and sandboxing limits to prevent unauthorized code execution within native apps.
- Monitor for unexpected resource usage or memory spikes that could indicate hidden processes or mods.
- Verify the source and integrity of any modified game files before installation or execution.
- Keep operating systems and security software updated to mitigate risks from unverified code injections.
