Tool Use

Noun · AI & Machine Learning

Definitions

  1. The ability of an LLM to invoke external tools (functions, APIs, databases, code interpreters) to accomplish tasks beyond text generation. The model decides when to call a tool, generates the parameters, and incorporates the result. Transforms LLMs from text generators into general-purpose agents.

    In plain English: When an AI can call external programs and APIs to get real information or take actions, not just generate text.

    Example: "The AI assistant uses tool use to check the weather API, query the database, and send an email — all orchestrated by the model's reasoning."
