Build a Supervisor Multi-agent Architecture with LangGraph
In this tutorial, you'll learn how to create a powerful multi-agent system using LangGraph, where a Supervisor Agent coordinates multiple worker agents to solve complex tasks.
We’ll build the complete architecture step by step in Python.
📌 What You’ll Learn
What a Supervisor Multi-Agent Architecture is
How the Supervisor Agent decides which worker should act next
How to define shared state in LangGraph
How to create worker agents
How to build the graph with nodes and edges
How to implement routing logic
How to run the graph until completion
🧠 Multi-Agent Architecture
In this tutorial, the Supervisor coordinates three specialist agents:
Researcher → Gathers facts and external information
Analyst → Identifies patterns and insights
Writer → Produces polished final output
The Supervisor Agent:
Examines the current state
Chooses the next worker
Updates the graph state
Continues until the task is complete
🛠 Technologies Used
Python
LangGraph
LangChain
OpenAI API
GPT-4o-mini
🏗️ Step-by-Step Workflow
Define the graph state
