TL;DR. The ability of an AI model, especially an LLM agent, to autonomously identify, select, and utilize external tools and APIs to accomplish tasks.

Technical Definition

The ability of an AI model, especially an LLM agent, to autonomously identify, select, and utilize external tools and APIs to accomplish tasks.

How it works

Tool use significantly expands the capabilities of LLMs beyond text generation. By integrating with external tools (e.g., search engines, calculators, code interpreters, custom APIs), an AI agent can overcome its inherent limitations, such as lack of up-to-date information or inability to perform complex calculations. This allows for more powerful and versatile problem-solving.
