How to Build Multi-Agent Systems for Complex Workflows
Multi-agent systems represent a powerful paradigm for handling complex, interconnected workflows that single AI agents struggle with. By orchestrating multiple specialized agents, organizations can tackle sophisticated problems with greater efficiency and accuracy.
Why Multi-Agent Systems?
Complex workflows often require diverse expertise, parallel processing, and sophisticated coordination - capabilities that multi-agent systems excel at providing through specialized, collaborative AI agents.
Core Architecture Patterns
1. Sequential Pattern
Agents work in a linear chain, where each agent's output becomes the next agent's input. Perfect for workflows with clear dependencies.
Research Agent → Analysis Agent → Writing Agent → Review Agent2. Hierarchical Pattern
A manager agent delegates tasks to specialized worker agents and aggregates their results. Ideal for complex tasks requiring diverse expertise.
Manager Agent → [Data Agent, API Agent, Analysis Agent] → Synthesis3. Collaborative Pattern
Multiple agents work together on shared state, communicating through a message bus or shared memory. Best for iterative refinement tasks.
