What is function-calling?

What is Function Calling?

Function calling is a fundamental concept in programming in which a specific block of code (function) is invoked or executed from another part of the code. allowing for modular, reusable, and efficient code. For example, a function to calculate the sum of two numbers can be called multiple times with different inputs, rather than rewriting the code each time.

How Function Calling Works

Fundamentally, function calling allows the chatbot to execute custom functions in response to user inputs. This means that instead of relying solely on static responses, the chatbot can use a set of predefined functions to perform specific actions. These functions can range from retrieving real-time data to executing complex operations, providing users with a more personalised and interactive experience.

For example, if a user inquires about the latest product prices, the chatbot can dynamically call a pricing function to fetch up-to-date information from the database. This ensures that users receive accurate and relevant data, enhancing the overall user experience.
