Building AI Agents from Scratch: Understanding the Core Components Behind the Magic
Introduction As a data scientist and AI engineer, I’ve spent countless hours working with various agentic frameworks like LangGraph, AutoGen, and CrewAI. While these tools are incredibly powerfull and make our lives easier, I often found myself wondering: what actually happens under the hood? What makes an AI agent tick?
