Build a Router Agent in Python Step by Step | LLM + Tools Explained

🚀 Build your first Router Agent in Python step by step! In this tutorial, you'll learn how to create a Router Agent that intelligently classifies a user request and dispatches it to the most appropriate specialist agent, such as a Writer, Coder, or Analyst. We’ll build the entire system from scratch using Python and the OpenAI API. 📌 What You’ll Learn What a Router Agent is How Router Agents differ from ReAct Agents How to define specialist agents How to create a routing prompt How to connect the router to an LLM How to select the best specialist agent How to call the selected agent How to return the final response 🧠 Example Query Write a haiku about gradient descent. The Router Agent will: Analyze the user request Compare it against available specialist agents Select the Writer Agent Forward the request to the Writer Agent Return the generated haiku 🛠 Technologies Used Python OpenAI API GPT-4o-mini Multi-Agent Architecture 🏗️ Step-by-Step Workflow Define Specialist Agents Create the Router System Prepare Messages Call the Router LLM Identify the Selected Agent Call the Specialist Agent Return the Final Answer 🤖 Specialist Agents in This Tutorial Writer Agent – Creative writing and storytelling Coder Agent – Programming and debugging Mathematician Agent – Calculations and proofs 🎯 Why Router Agents Matter Router Agents are useful when you have multiple specialized agents and want the LLM to decide which one should handle each query. This pattern is widely used in: Multi-agent systems Customer support automation AI copilots Enterprise workflows Agent orchestration frameworks 🌐 Try It Yourself You can try building agents on my platform: Data Jarvis AI → Select the Agent Builder app. 🔔 Subscribe for More AI Tutorials If you're interested in: AI Agents OpenAI API Python Automation Multi-Agent Systems Generative AI Subscribe to the channel for more practical, step-by-step tutorials. 🏷️ Hashtags #RouterAgent #MultiAgentSystems #PythonAI #OpenAI #AIAgents #LLM #OpenAIAPI #PythonTutorial #aiengineering #GPT4o #AgentOrchestration #artificialintelligence GitHub: https://github.com/pranaydave/data_jarvis_public/blob/main/agent_building/router_agent.py Try this out on my platform: https://datajarvis.ai
