AI Agent Hierarchy Explained Like You're 5
Ever wondered what actually separates a "dumb" AI from a genuinely smart one? Turns out you can explain the entire AI agent hierarchy using something you do every single morning — making coffee.
In this video, I break down all 6 classic types of AI agents, one upgrade at a time, using one running example so you never lose the thread:
☕ Simple Reflex Agent — reacts with zero memory
☕ Simple Reflex Agent with State — adds basic memory, still no planning
🧠 Model-Based Reflex Agent — builds an internal picture of the world
🎯 Goal-Based Agent — starts planning toward a specific outcome
⚖️ Utility-Based Agent — weighs competing priorities, not just one goal
📈 Learning Agent — adjusts itself based on real feedback over time
Each type exists because the one before it hit a wall. This video walks through exactly where that wall was — and how the next version got past it.
If you're trying to understand AI agents for work, for building your own automations, or just to keep up with where AI is actually headed, this is the clearest way to get it.
