Multi-agent AI systems are transforming how we tackle complex problems across industries by creating collaborative networks of specialized agents. The adoption of these systems requires standardized benchmarks for evaluation, which can be challenging due to the complexity and variability of multi-agent environments. Several benchmarks have been developed to address this need, including MultiAgentBench, BattleAgentBench, SOTOPIA-π, MARL-EVAL, AgentVerse, SmartPlay, and industry-specific benchmarks. These benchmarks offer a range of evaluation frameworks, from comprehensive and modular designs like MultiAgentBench, to specialized approaches like SOTOPIA-π for social intelligence testing, and industry-specific tools like supply chain optimization benchmarks. Each benchmark has its strengths and limitations, and the choice of which one to use depends on the specific use case and requirements. By understanding these benchmarks, researchers and developers can select the right evaluation tool for their multi-agent systems and improve their performance in complex environments.
