Fable 5.1 World Modeling
Fable 5.1 is a project that uses autonomous AI agent swarms to generate explorable, browser-native 3D reconstructions of real-world locations using open data. The project avoids traditional game engines, instead relying on code to render environments like San Francisco's Union Square.
Why it matters
It demonstrates a novel, automated approach to digital twin creation and urban modeling without proprietary software.
Worlds via code. Explorable, browser-native reconstructions of real places — researched, modelled, and quality-checked end to end by autonomous Claude Fable 5.1 agent swarms, then shipped as plain Three.js apps you can run with npm run dev .
No game engine. No proprietary 3D tiles. Every building, storefront, sign, tree and traffic light is generated from open data and public reference imagery by code that lives in this repo.
