ProtoLive

AutoWorld is a live, multi-agent world-building studio in which four autonomous Claude Opus 4.8 agents project the future of San Francisco as four navigable 3D worlds — one shared city running down four diverging timelines. Each agent owns a window and, on every tick, independently interprets the same real-world indicators into its own thesis, then cross-critiques the other three with cited evidence rather than opinion and self-optimizes from the feedback it accepts, so the four futures stay distinct but honest. You shape the worlds by typing events into a shared chat — "Major earthquake" hits all four, while @1 mayor built 2,000 shelters targets just one — and the agents interpret, reconcile, and reshape their cities in response, reaching for the prepackaged 3D asset library first and generating new assets with Meshy only when nothing fits. Every panel (ideally) renders instantly from a procedural Three.js baseline of the real SF skyline — Golden Gate, the Bay Bridge, Alcatraz, the wharf, downtown — that you can click into and walk with WASD, and a running changelog audits every divergence, critique, and asset spend. The result is less a simulation than a debate made visible: four reasoning agents keeping each other accountable while turning live data and human prompts into worlds you can step inside.
