On a tangent note, actually there are two types of structured data extraction, Function Calling and through response_format , but i suppose in llama-index we are doing Structure Output Extraction i.e. llm.as_structured() using only Function Calling
I would also like to know more about this, as I am planning to use entity extraction on a larger scale with around 5 to 60 entities being extracted so, i would need some guarantee of the output format.
