Getting Up to Speed on Multi-Agent Systems, Part 7: Benchmarks and What They Miss
Most MAS benchmarks were designed for single agents and can't measure coordination quality, communication overhead, or failure recovery — causing papers like ChatDev and MetaGPT to report contradictory results while multi-agent overhead only pays off on breadth-first, parallel-decomposable tasks.

- AI agents
AI agents are LLM-powered systems that plan, act, and iterate autonomously; active research and engineering practice reveal deep tensions between coordination complexity, reliability, tool design, and the human oversight they still require.
- AI-assisted coding
AI coding assistants accelerate development but introduce tradeoffs around skill atrophy, codebase design, verification, and security that shape how much value they actually deliver.
- Multi-agent systems
LLM-based multi-agent systems coordinate multiple AI agents on decomposed tasks, but empirical work shows failure rates of 41–87%, with information synthesis rather than coordination being the core bottleneck.
