OpenAI’s addition of function calling builds on instruction tuning. By describing functions in a schema, developers can tune LLMs to return structured outputs adhering to that schema – for example, extracting entities from text by outputting them in a predefined JSON format.

Function calling enables developers to create chatbots that can answer questions using external tools or OpenAI plugins. It also allows for converting natural language queries into API calls or database queries and extracting structured data from text.

Developers can now describe functions to the gpt-4-0613 and gpt-3.5-turbo-0613 models and have the models intelligently generate a JSON object containing arguments to call those functions. This feature aims to enhance the connection between GPT models and external...
