ELI5: how ai agents work

What is an AI agent?

An AI agent is like a robot assistant that lives inside a computer [1]. It watches what's happening around it, thinks about what to do, and then takes action all by itself, kind of like how you might clean your room without being told [5].

How does it decide what to do?

First, the AI agent looks at information (like emails or documents), then it uses a big brain called a language model to think about what the best action is [2]. It's like when you see your toy is messy and decide to pick it up [1].

What jobs can it do?

AI agents can help with tasks like organizing your schedule, finding information, or even writing code [4]. Right now, most agents are still learning and handle smaller jobs like summarizing research or filtering emails [3].

How does it keep learning?

The agent keeps watching what happens after it takes action and gets better over time [5]. It's like learning to ride a bike — you try, see what works, and get better at it [2].
