Build a Supervisor Multi-agent Architecture with LangGraph

Description

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 Create specialist worker nodes Build the Supervisor node Add conditional routing logic Connect nodes with edges Compile the graph Run the multi-agent workflow 🎯 Example Use Cases Supervisor architectures are ideal for: Research assistants Content generation pipelines Data analysis workflows Business intelligence systems Autonomous AI teams 🤖 Why Use LangGraph? LangGraph makes it easy to build agent systems with: Shared state Conditional branching Iterative loops Human-in-the-loop controls Durable execution 🌐 Try It Yourself You can experiment with AI agents on my platform: Data Jarvis AI → Open the Agent Builder app. 🔔 Subscribe for More AI Tutorials If you're interested in: LangGraph AI Agents Multi-Agent Systems OpenAI API Python Automation Subscribe for more practical, step-by-step tutorials.
