AI Agent
What AI Agent means, how it works, and which tools and models on this site relate to it.
Definition
An AI agent is a system that uses a model to choose actions — tools, code, browsers, or APIs — toward a goal, often in a loop.
How it works
The model plans, calls a tool, reads the result, and continues until it stops or hits a limit. Reliability depends on tool design, permissions, memory, and evaluation — not just the base model.
