What Does This Mean?
A mechanism that lets a large language model interact with external systems, applications or data sources: the model returns a structured request to call a tool, the surrounding program runs it and sends the result back so the model can continue. Also called function calling or tool calling.

REAL-WORLD EXAMPLE
""With tool use turned on, the assistant looked up the weather instead of guessing.""
LORE & ORIGIN
Wikipedia describes tool use as a program separate from the model watching its output for a special tool-calling syntax and running the tool; Anthropic's documentation states that tool use (also called function calling) lets Claude call functions that a developer defines or that Anthropic provides. Recent term; no dated source found yet for its first use.
