Today, OpenAI introduced a Function Call API so we're going to dive into a much more structured and efficient way of handling output parsing when interacting with OpenAI. This method leverages the robustness of the Pydantic library in tandem with the recent improvements in OpenAI's API.
Historically, dealing with output parsing, especially with JSON responses, has been fraught with complexities. Ensuring the extracted data adheres to a specific schema or matches certain function calls often involves writing intricate and cumbersome error-checking code. Add to this the vagaries of AI and you often end up reasking and hoping it does a better job.
However, Pydantic, a Python library that provides data validation through Python type annotations, comes to the rescue! And when combined with OpenAI's new function call capabilities, it allows us to handle output parsing in a much more structured and reliable way with a much better d
