But what happens when you need an agent that researches *while* another agent writes *while* a third agent monitors quality? You need a **multi-agent system** — multiple specialized agents working together, each handling a piece of a larger workflow. Multi-agent architectures are exploding in 2026. From CrewAI and AutoGen to custom orchestration with Claude and GPT, teams are discovering that **a team of focused agents outperforms one general-purpose agent** on complex tasks. But multi-agent systems also introduce coordination overhead, higher costs, and debugging nightmares if built wrong. This guide covers when multi-agent systems make
