AI Agents Explained - How They Actually Work

How AI agents can search, code, debug, and fix — all without you touching the keyboard? It's not a smarter AI. It's the same language model with different scaffolding. In this video, I break down exactly what's happening inside AI agents — the loop, the tool calls, the memory systems, and where it all falls apart. What you'll learn: → The ReAct pattern that powers virtually every agent framework → How tool calling actually works (model proposes, your code executes) → Why agents forget and how memory systems solve it → Common failure modes you'll hit if you build with agents → A mental model …
