The Hugging Face blog features Thousand Token Wood, a project from the Build Small Hackathon that shows a multi-agent economy simulation running entirely on a 3-billion-parameter model. The simulation places autonomous AI agents in a shared virtual world where they can trade resources, construct buildings, and form cooperative strategies.
The project is notable for its efficiency: rather than requiring a large frontier model, it runs on hardware that consumers and small teams can access. Each agent operates within a tight token budget, making decisions about resource allocation and collaboration with other agents in the simulation.
The authors describe the architecture as a step toward understanding emergent behaviors in multi-agent systems and exploring how small, efficient models can power complex agent-based applications. The full source code and implementation details are available on Hugging Face.
