AI Agent

Definition

An autonomous AI system powered by an LLM that can perceive its environment, make decisions, create plans, and execute actions using external tools to achieve a specific goal.

Explain Like I'm New

ChatGPT is just a brain in a jar—it can only talk. An AI Agent is a brain with hands. You tell it 'Book me a flight to NY'. It autonomously opens the web browser, reads the prices, clicks the buttons, and enters your credit card.

Real World Example

AutoGPT or Devin (the AI software engineer). You give Devin a goal: 'Build a snake game'. Devin writes the code, runs the code, reads the error message, Googles how to fix the error, and fixes the code without you doing anything.

Common Use Cases

•Workflow automation
•Autonomous research
•Coding assistants
