Function Calling

Function calling allows Large Language Models (LLMs) to interact with external tools and APIs. Instead of just generating text, the LLM can be instructed to recognize when a specific function should be called based on the user's input, and then output the arguments needed to execute that function. This enables the LLM to perform actions beyond its training data, such as retrieving real-time information or automating tasks.
