    "abstract": "Zero-shot coordination (ZSC)—the ability to adapt to new partners in a cooperative task—is critical for human-compatible AI. While prior work has focused on training agents to cooperate on a single task, these specialized models fail to generalize to new tasks, even if similar. We study how reinforcement learning on a distribution of environments with a single partner induces general cooperative skills that support ZSC with many new partners on many new problems. We introduce two Jax-based procedural generators that create billions of solvable coordination challenges. We develop a new paradigm called Cross-Environment Cooperation (CEC), and show that it outperforms baselines quantitatively and qualitatively when collaborating with real people. Our findings suggest that learning to collaborate across diverse scenarios encourages agents to develop general norms effective for collaboration. Together, our results suggest a new route toward designing generalist cooperative agents that interact with humans without requiring human data.",
