YC Labs and Olam Labs have open-sourced tools for running teams of AI agents in Minecraft and Mindustry. The release includes a Minecraft harness and a framework that gives multiple agents separate computing environments, messaging and access to a shared game through software interfaces.

In a reported Minecraft experiment, 50 agents developed a hierarchy and food rationing system but became increasingly cautious after early deaths. The Mindustry tools support configurable team competitions and a survival environment for up to 20 agents. Running the experiments requires a model provider API, an agent harness and compute; the researchers used generic harnesses without special memory customization.
