City Bots Demo: Multi-Agent World Simulation with Physics Engine
ProfBuehlerMIT · x · 2026-08-27
The City Bots project by SwarmWorld is a world simulator allowing users to coexist with thousands of AI agents.
Core Features & Config
- AI Citizens: Each citizen is an independent agent that users can chat with, direct, or observe.
- Custom Worlds: Supports generating worlds via text description, with adjustable map sizes (16x16 to 256x256).
- BYOK: Driven by API keys from OpenRouter, OpenAI, or xAI. Note that costs can be high with massive concurrent agent calls.
- Tech Params: Adjustable parallel LLM calls, agent sensing radius, actions per turn, and physics engine tick rate.
Technical Details
The system feeds agents' action plans into a physics engine, where physical rules determine the outcomes, demonstrating the emergent behavior of "recursive AI creating AI worlds." A web interface is currently available for direct play.
