What is a multi-agent system? A complete guide

Overview

Hot take: I really liked the "Stranger Things" finale. Yeah, the final fight was formulaic, but I love a good boss fight. Everyone has a specialty, and they all contribute to the win.

Key Takeaways

  • Multi-agent systems (MAS) are a collection of AI agents that can collaborate and work autonomously to achieve business goals.
  • Like Dustin and Steve, they're better together.

    In this guide, I'll break down what a multi-agent system is, how it works, where it helps (and where it creates new problems), and a few practical ways teams are using multi-agent setups at work.

  • A single-agent system is one intelligent AI agent that performs defined tasks.

    For example, one agent could generate a meeting transcript and send it to participants, summarize your daily calendar in Slack, or assign to-dos based on overdue tasks.

  • Multiple specialized agents can sometimes be more reliable than a single agent for multi-step workflows because you can narrow the scope at each step.

    Large language models (LLMs) are probabilistic, not deterministic , meaning they generate likely outputs rather than guaranteed ones.

  • The agents are individual entities with defined behaviors working within structures.

Multi-agent systems (MAS) are a collection of AI agents that can collaborate and work autonomously to achieve business goals. Learn more about them in our guide. See how Zapier helps you manage, secure, and scale automation across your organization.

Three phases to move from disconnected AI pilots to orchestrated systems that scale. Hot take: I really liked the "Stranger Things" finale. Yeah, the final fight was formulaic, but I love a good boss fight.

Everyone has a specialty, and they all contribute to the win. That's how high-performing teams work everywhere, whether it's a psychic, demon-fighting group of teenagers or an automation system. AI agents can do a lot on their own, but organized into a multi-agent system, they can specialize, share information, and delegate.
