Part 5/9:
It's also crucial to note that not all versions of OpenAI's models support structured outputs. For example, the latest models like GPT-4 Mini are equipped with this feature, while older versions, such as GPT-3.5, are not and will require the use of JSON mode as a workaround.
Implementing Structured Outputs
To implement structured outputs with function calling, developers must specify the strict parameter set to true in their function definitions. This ensures that the returned data adheres to the expected structure. In cases where certain features are unsupported or when APIs require dynamic schemas that change frequently, developers may choose not to use structured outputs.
