Tool Calling
[/tuːl ˈkɔːlɪŋ/]
Definitions
A capability that allows language models to invoke external functions, APIs, or services during generation. The model decides when to call a tool, formats the call arguments as JSON, receives the result, and incorporates it into its response — enabling real-world action beyond text generation.
“The agent used tool calling to check the current weather before generating its travel recommendations.”
