AI Agents Explained: How Autonomous AI Works

AI agents go beyond chat — they observe, plan, act, and iterate in a loop until a task is done. From booking flights to writing and running code, agents are the reason AI is moving from "answer questions" to "do things." This path breaks down the agent architecture: how the agent loop works, the design patterns behind reliable agents, what multi-agent systems look like, and critically, how to keep humans in control when autonomous AI makes mistakes.

What You'll Learn

  • 1What defines an AI agent and how it differs from a chatbot or a workflow
  • 2The agent loop: observe, think, act, and how agents decide when they are done
  • 3Design patterns like ReAct, plan-and-execute, and reflection that make agents reliable
  • 4Multi-agent systems: when one agent is not enough and how agents collaborate
  • 5Function calling and tool use — the mechanism that lets agents interact with the real world
  • 6Failure modes, guardrails, and human-in-the-loop strategies for safe autonomous AI
