get_openai_output_parser#
- langchain.chains.structured_output.base.get_openai_output_parser(functions: Sequence[Dict[str, Any] | Type[BaseModel] | Callable]) BaseOutputParser | BaseGenerationOutputParser[source]#
Get the appropriate function output parser given the user functions.
- Parameters:
functions (Sequence[Dict[str, Any] | Type[BaseModel] | Callable]) – Sequence where element is a dictionary, a pydantic.BaseModel class, or a Python function. If a dictionary is passed in, it is assumed to already be a valid OpenAI function.
- Returns:
- A PydanticOutputFunctionsParser if functions are Pydantic classes, otherwise
a JsonOutputFunctionsParser. If there’s only one function and it is not a Pydantic class, then the output parser will automatically extract only the function arguments and not the function name.
- Return type:
