langchain.agents.output_parsers.openai_functions.OpenAIFunctionsAgentOutputParser¶
class langchain.agents.output_parsers.openai_functions.OpenAIFunctionsAgentOutputParser[source]¶
Bases: AgentOutputParser
Parses a message into agent action/finish.
Is meant to be used with OpenAI models, as it relies on the specific
function_call parameter from OpenAI to convey what tools to use.
If a function_call parameter is passed, then that is used to get
the tool and tool input.
If one is not passed, then the AIMessage is assumed to be the final output.
Create a new model by parsing and validating input data from keyword arguments.
Raises ValidationError if the input data cannot be parsed to form a valid model.
async abatch(inputs: List[Input], config: Optional[Union[RunnableConfig, List[RunnableConfig]]] = None, *, return_exceptions: bool = False, **kwargs: Optional[Any]) → List[Output]¶
Default implementation of abatch, which calls ainvoke N times.
Subclasses should override this method if they can batch more efficiently.
async ainvoke(input: str | langchain.schema.messages.BaseMessage, config: langchain.schema.runnable.config.RunnableConfig | None = None, **kwargs: Optional[Any]) → T¶
Default implementation of ainvoke, which calls invoke in a thread pool.
Subclasses should override this method if they can run asynchronously.
async aparse(text: str) → T¶
Parse a single string model output into some structure.
Parameters
text – String output of a language model.
Returns
Structured output.
async aparse_result(result: List[Generation], *, partial: bool = False) → Union[AgentAction, AgentFinish][source]¶
Parse a list of candidate model Generations into a specific format.
