Multi-Agent Systems: When One Agent Isn’t Enough
Multi-Agent Systems: When One Agent Isn’t Enough
The intuition
If a problem requires different skills (research, coding, reviewing) or parallel work, splitting responsibilities into multiple agents can improve quality and speed.
When multi-agent is worth it
- Parallel research and summarization
- Separation of duties (generator vs reviewer)
- Complex workflows with specialized tools
When it’s overkill
If a single agent can solve it with good tool use and memory, multi-agent adds overhead: coordination, latency, and failure modes.
