Also known as: AI agent, intelligent agent, agentic AI system
What is an AI agent?
An AI agent goes beyond generating a single response. It can interpret a goal, decide what to do next, use tools when necessary, observe the result of an action, and continue until the task is complete.
Simple example
A travel-planning agent could understand your destination and dates, search for relevant information, compare options, adjust its plan based on results, and return a final recommendation.
Why AI agents matter
Agents turn AI models from passive answer generators into systems that can perform multi-step work toward a goal.
