A real open world
A dense, living coastal city with seamless streaming: vehicles, crowds, water, and weather. The bar is modern AAA fidelity, not a tech demo.

GT CALIBER
An AAA open world, vibe coded in the open.

THE PROJECT
What is GT Caliber?
GT Caliber is an original open world game on Unreal Engine 5, with one twist in how it gets made: AI agents write it, in public, using a custom set of skills and plugins built for the job.
Built by AI agents
AI agents do the building. They plan, write the systems, and wire up gameplay, working through the roadmap one piece at a time.
Custom skills and plugins
The agents run on a kit of custom skills and plugins made for game work, so each pass lands real gameplay instead of boilerplate.
Built in the open
Community driven and open source. The code lives on GitHub and the work happens in public, commit by commit.
ROADMAP
Built to grow.
GT Caliber is an original open world action game on Unreal Engine 5, built to be extended. Most open world games are sealed boxes that stop growing the day they ship. GTC keeps growing because players and creators make their own cars, missions, and looks. The community is the moat. The foundation is already playable: you can control a character and drive a real city, with combat and economy systems built and tested underneath.
- A controllable character in a good looking, fully lit world
- Get in a car, drive it, get out, smoothly
- One complete activity start to finish, a race or a job
- Enough polish that a 60 second clip sells the vision
CLAUDE CODE, LIVE
WEBHOOK LIVEThe tokens this build has burned.
Every Claude Code session that ships GT Caliber posts its token usage here, straight from a Stop hook. Claude Code on a subscription isn't billed per token, so the dollar figure is the estimated API-equivalent value, not a real charge.

THE TOKEN
A community coin, not the point.
GT Caliber is a game first. $B4GTA6 is a community token on Solana that rallies around it. It does not fund a promise and you never need it to follow the project or play the game.
CONTRACT · SOLANADexscreener
Verify the address before trading. Scammers clone names and tickers. This is the only official $B4GTA6 contract.
