LLM

What is function calling / tool use in LLMs, and why does it matter?

The question is about LLM .

Answer:

Function calling, also called tool use, lets a model request that a specific function be run with specific arguments, such as looking up a database record or calling an external API, instead of only generating text. It matters because it's what turns an LLM from something that answers questions into something that can take real actions inside an application, which is the core mechanism behind most AI agents.
