Agent
Also known as: AI Agent, Autonomous Agent
In one sentence
An AI system that can use tools, make decisions, and take actions to complete tasks autonomously rather than just answering questions.
Explain like I'm 12
Instead of just telling you the answer, an agent can actually do things for you—like searching the web, running code, or booking a flight.
In context
AI agents can research topics by searching multiple sources, write and execute code to analyze data, or interact with APIs to accomplish multi-step tasks.
