What Is an AI Agent and How Does It Work?
Artificial intelligence is no longer just about answering questions. A new generation of AI systems — called agents — can plan, decide, and act on their own to complete complex tasks. But what exactly is an AI agent, and how is it different from the AI tools you may already be using? The basic idea An AI agent is a software system that perceives its environment, processes information, and takes actions to achieve a specific goal, often without a human having to guide every step. Unlike a chatbot that responds to a single prompt, an agent can break a task into steps, execute each one, evaluate the result, and adjust its approach along the way. Why it matters now Three things changed at once: models got good enough to plan, tools became callable from a conversation, and the systems around them learned to keep a record. Together they turn a clever answer into finished work.
