Alem (Easy) - Coordination: leaderboard
The coordination return on the easy difficulty of Alem (2026), a multi-agent Craftax-like world for LLM agent teams: reward earned from synchronous, all-agent and handover coordination tasks as a percent of its maximum. Higher is better.
Metric: Coordination return (%): each agent's reward from coordination tasks divided by its maximum (159) and averaged across agents on the Easy difficulty, zero-shot homogeneous team (every agent driven by the same LLM) in alem, a JAX Craftax-like open-ended multi-agent world with procedurally generated coordination tasks (synchronous, all-agent and handover) and soft role specialisation; text interface with the rules, local observation and legal actions each step, scratchpad memory, broadcast communication and the last eight observations; reasoning enabled where available, proprietary models at high reasoning; mean over 20 seeds (10 for the API models); higher is better.
