WorkflowArena Benchmark: Top LLMs Achieve Only 36.95% in Multi-Agent Orchestration
Einsia AI's WorkflowArena benchmark evaluates 9 frontier models across 145 long-horizon tasks in 8 domains, revealing that even the best system (Claude Opus 5.5) achieves only 36.95% full solve rate, exposing multi-agent orchestration as a critical weakness, with distinct orchestration styles between Claude and GPT models, and showing that strong orchestration can significantly boost weaker executors.
