AI Agent (Agentic AI)

An AI system that can take actions on its own, such as using tools, browsing, or running code, to complete a multi-step task rather than just answering.

Why it matters

Agents move AI from answering questions to actually doing work, which is the direction most of the industry is heading.

Example

An agent that reads a bug report, edits code, runs tests, and opens a pull request.
