Fable 5.1 World Modeling

Fable 5.1 has unveiled a new feature called "World Modeling." This innovative technology allows for the creation of explorable, browser-native reconstructions of real places. These reconstructions are meticulously researched, modeled, and quality-checked by autonomous "Claude Fable 5.1" agent swarms.

The worlds generated using this system can be shipped as plain Three.js applications, running simply with the command "npm run dev." No game engine is required, and there are no proprietary 3D tiles involved. Every element, from buildings and storefronts to signs, trees, and traffic lights, is generated from open data and public reference imagery through code within the repository.

The demonstration showcases the square and its surrounding blocks on real terrain and a real street grid, including Powell, Geary, Post, and Stockton avenues. The area features 129 identified storefronts, functioning traffic lights, cable cars, and visuals of day, sunset, and night. Two explorable interiors are also included: Apple Union Square (300 Post St) and Nintendo San Francisco (331 Powell St).

The entire pipeline for creating these worlds is documented in the repository, with all stages available for re-running. The code and generated assets are licensed under MIT. Geometry in these worlds is derived from OpenStreetMap (ODbL) and USGS 3DEP, both of which are in the public domain.

Reference photographs, though not redistributed, are sourced and documented per sector in the world's "refs/*/SOURCES.md" files. Brand names and logos in the worlds accurately identify the real businesses at their physical locations, respecting their owners' rights.
