COOL WORLD

A scaled-down local rebuild of an AI society. Five citizens with layered memory, a credit economy, and a constitution they can amend, running on a local model as a terrarium.

Five simulated citizens in a small town, with memory, money, and a constitution they can change, all running on my own hardware. A terrarium, not a product.

Stack

A Python backend with SQLite and an event log, a local language model and embeddings, a 64-tool registry. A viewer in React and React Three Fiber.

Highlights

  • The engine is ground truth. Agent beliefs never mutate world facts, because hallucinations cascade agent to agent.
  • Ambient mode. Ten-minute beats, load, act, unload, near-zero GPU between beats, after the always-on version was ruled to be living beyond its means.
  • A finished 3D town viewer at dusk with citizen, governance, and event panels.
