Parallel Function Calling for Structured Data Extraction

OpenAI introduced function calling in early 2023, which encourages language models to respond in a structured format. This has been particularly useful for extraction, the process of extracting structured data from unstructured documents. With old function calling, developers had to use hacks to extract multiple pieces of information at once. However, with parallel function calling, developers can now pass in different types of objects directly as functions and receive separate function calls as output. This significantly simplifies the extraction process and reduces the complexity of input and output logic for language models.
