The process involves defining a Pydantic BaseModel representing the desired JSON structure for handling data in Python using LLMs and LangChain library.
The .with_structured_output() method is used directly on the chat model to enforce the output conforms to the specified schema.
LangChain simplifies prompt engineering and validation processes, making it easier to work with LLMs.
The structured_llm object ensures the model outputs data in the desired format and includes built-in retry logic if needed.
