What is Multi-Agent System?

Quick answer

A setup in which several AI agents, each with its own role or tools, work together or hand off tasks to reach a shared goal.

Multi-Agent System, explained

Rather than asking one agent to do everything, a multi-agent system divides work among specialized agents. One agent might plan the task, another might research, another might write, and a reviewer agent might check the result. An orchestrator coordinates the hand-offs.

For example, a marketing team could use a research agent to gather product facts, a drafting agent to write a product page, and a checking agent to compare claims against approved sources before a person signs off. Splitting roles can make complex workflows easier to manage and test. However, more agents mean more model calls, higher cost, and more places for errors to spread. Many teams find a single well-designed agent with good tools is enough until a workflow genuinely needs division of labour.
