# What Is a Multi-Agent System?

> A multi-agent system coordinates multiple specialized AI agents — each with distinct roles and tools — to solve complex tasks that exceed a single agent's scope.

A **multi-agent system** coordinates multiple AI agents — each with its own role, tools, and instructions — to accomplish tasks too complex for a single agent.

Instead of one generalist agent trying to do everything, you decompose the work:

- A **research agent** gathers information
- A **writer agent** synthesizes findings into a report
- A **reviewer agent** checks for accuracy and gaps
- An **orchestrator** routes work and manages handoffs

## When to use multiple agents

Multi-agent architectures make sense when:

- Tasks have **distinct phases** that benefit from specialized prompts and tools
- **Parallel work** is possible (multiple research threads simultaneously)
- **Quality checks** need separation from generation (a reviewer shouldn't share the writer's context)
- A single agent's context window or capability set is insufficient

## When one agent is enough

Many teams over-engineer multi-agent setups. A single well-architected agent with good tools often outperforms a swarm of poorly coordinated specialists. Start with one agent; split only when you hit clear bottlenecks.

## Orchestration patterns

- **Sequential pipeline** — Agent A output feeds Agent B
- **Supervisor** — A lead agent delegates to specialists and synthesizes results
- **Debate / consensus** — Multiple agents propose solutions, a judge selects the best
