YC let agent swarms battle in Minecraft and Mindustry — OpenAI models retrieved source code to beat Claude
ycombinator · x · 2026-10-30
Y Combinator Labs, with Olam Labs, ran experiments letting agent swarms compete in Minecraft and Mindustry over long periods in a shared world.
Key findings:
- Emergent "civil bureaucracy" among agents
- Thousands of telegraphic agent-to-agent messages
- OpenAI models retrieved the game's source code to beat Claude
The team argues games are the best medium for making multi-agent dynamics legible to humans.
