Agents & Automation

Tool Use

The ability of an AI to use external tools — calculators, search engines, databases, APIs.

Definition

Tool use extends an AI's capabilities beyond what it can do with language alone. By equipping a model with tools — a web search API, a calculator, a database query interface, a code execution environment — the model can perform tasks that require external information or computation. This is fundamental to building AI agents that interact with the real world rather than just generating text.
