Build Your First AI Agent: From Chatbot to Problem Solver with LangChain

What if your AI could decide what to do, call the right tools, and even improve based on what it learns—all without constant prompting? That’s the magic of agents. In this tutorial, we’ll build your first real AI agent using LangChain and OpenAI. Think of it as training a junior teammate—not just to answer questions, but to solve problems step by step. With simple Python code and no prior experience with LangChain needed, you’ll go from zero to agent in under 15 minutes.
