CoffeeBench: Benchmarking Long-Horizon LLM Agents in Heterogeneous Multi-Agent Economies

Innovation Summary

CoffeeBench: Benchmarking Long-Horizon LLM Agents in Heterogeneous Multi-Agent Economies: We introduce CoffeeBench, a benchmark for evaluating LLM agents in a long-horizon multi-agent economy composed of heterogeneous firms.

Executive Summary

CoffeeBench: Benchmarking Long-Horizon LLM Agents in Heterogeneous Multi-Agent Economies: We introduce CoffeeBench, a benchmark for evaluating LLM agents in a long-horizon multi-agent economy composed of heterogeneous firms. Why it matters: Overall signal 82/100 driven by novelty 77 and practical impact 100. Primary categories: LLM agents, agent behavior, autonomous agents, communication, cumulative net income, economic systems. Community signal includes 4 upvote(s) and 1 comment(s), which helps separate durable interest from title-only curiosity. Implementation angle: Implementation potential scores 89/100; prioritize adaptation paths for internal agent, evaluation, or platform workflows. No linked repository is present, so expect more translation work before the ideas are production-ready. Technical depth scores 63/100, so a quick skim should focus on architecture, data, and evaluation sections before full adoption work. Caveat: Evidence appears benchmark-centric, so verify transfer to production workloads before acting on the claims.

Why It Matters
