How to Choose Between Single- and Multi-Agent Solutions
Drawing on Stanford and Google/MIT research, this piece argues that single-agent systems should be the default for most AI tasks, as multi-agent orchestration introduces a hidden coordination tax that can amplify errors up to 17x and cut tool-handling efficiency by 2–6x.

Cited by
- Agent coordination
How multiple LLM agents divide work, share state, and handle failures, with research showing that coordination structure must match task structure and that poor coordination causes the majority of multi-agent system failures.
- Agentic workflows
Systems where AI agents execute multi-step tasks autonomously, raising interconnected questions about harness architecture, state management, reliability engineering, human oversight, and the organizational context those agents operate within.
- AI agents
Autonomous systems that plan, act, and verify across tool calls and multi-step workflows, with active debate over architecture choices, coordination costs, memory design, state management, and the governance infrastructure needed to make them reliable.
- AI infrastructure
The systems, abstractions, and operational layers that make AI models usable at scale, from compute and caching to routing, governance, agent hosting, and credential management.
- Benchmarks
Benchmarks measure model or system capability, but their results are only as meaningful as their design — a recurring problem across LLM, multi-agent, and vision tasks, where tests built for one context are routinely applied to contexts they cannot capture.
