Originally published on Towards AI.

A few months ago, OpenAI introduced a new capability to its API, enhancing its most recent models to accept additional parameters for function calling. These models are now fine-tuned to determine when it’s relevant to call one of these functions. In this article, we’ll explore how to use this feature effectively, along with tips and tricks for optimal results.
We’ll use the OpenAI SDK to demonstrate this new capability, imagining a function we find valuable to provide to the language model. We’ll delve into what makes a function “interesting” and discuss various use cases for this new parameter.
