FAQ
What Are AI Agents?
An AI agent is a computer program or robot that can make decisions and take actions on its own. Imagine having a helper that never gets tired, never sleeps, and can think through a problem for you! AI agents can live in cyberspace as bits of code or in the real world as robots and smart devices.
But how do AI agents know what to do? They use “intelligence”: a mixture of rules, learning, and logic to understand their environment and pick the best action. Some are built to focus on specific tasks, while others can learn and get better over time.
They even come in teams called multi-agent systems—think of a superpowered robot soccer match, or a swarm of drones working together like ants! (source, source)
Types of AI Agents: Meet the Dream Team
AI agents come in different “personalities” or types, depending on how they make decisions:
1. Utility-Based Agents
These clever agents decide what action gets them the highest “score” or utility. For example, they might pick the quickest path to deliver your pizza or the cleanest way to manage energy in a smart home.
2. Goal-Based Agents
These are built with a finish line in mind: they want to achieve goals. They figure out how to get there step-by-step, planning routes and solving problems as they go.
3. Model-Based Reflex Agents
These agents see the world around them and act on “reflexes,” but with a twist: they also keep a mental map (or “model”) of what’s happening. That helps them respond in smarter ways to changes and surprises.
4. Learning Agents
The brainiacs of the AI world! Learning agents aren’t satisfied with what they know—they study, experiment, and get better as they go. Each challenge makes them faster, smarter, and more useful.
