Workflow
The team partnered with Olam Labs to study multi-agent dynamics by deploying 50 GPT-6.1 Sol agents in a custom, open-sourced Minecraft harness. Agents were tasked with building a civilization, utilizing tools like Mineflayer for world interaction and Pi for the agentic loop. They communicated via DMs and shared files to coordinate survival, resource gathering, and governance.
Reported result
The agents formed a pseudo-government with rationing ledgers but became highly risk-averse after 22 deaths occurred in the first night. The civilization shifted from expansion to survival, with agents huddling in shelters and abandoning ambitious tasks. GPT agents used truncated speech, while Claude agents frequently used collective pronouns like "we".
Human role
The original post does not say how a person stayed involved.
Limitations
The source does not specify human oversight protocols or operational costs for the 50-agent simulation. The environment lacked persistent consequences for death beyond gear loss, which may skew behavioral realism. Integration requires custom harnesses and specific Minecraft server configurations.
Try it
I want to replicate the Civ50 experiment to study agent coordination. Please set up a Minecraft server using the open-sourced harness from github.com/yc-software/minecraft-agent-harness. Deploy [replaceable number] GPT-6.1 Sol agents with the goal: "Build a thriving civilization." Ensure agents have access to a shared sandbox and DM capabilities. Before running the full simulation, execute a dry run with [replaceable small number] agents for 10 minutes to verify tool connectivity and message logging. Show me the initial logs and agent behaviors for confirmation before scaling up. Monitor for emergent hierarchies and risk-aversion patterns. If agents fail to interact or crash, pause and report the error logs. Do not proceed to the 3-hour full run without my explicit approval after reviewing the dry run results.
