z0.1.14a LangChain has introduced a method called `with_structured_output` thatis available on ChatModels capable of tool calling.You can read more about the method here: . Please follow our extraction use case documentation for more guidelineson how to do information extraction with LLMs.. If you notice other issues, please provide feedback here:z1.0a4

setup: str = Field(description="The setup of the joke")
punchline: str = Field(description="The punchline to the joke")
# Or any other chat model that supports tools.
# Please reference to to the documentation of structured_output
# to see an up to date list of which models support
# with_structured_output.
model = ChatAnthropic(model="claude-3-opus-20240229", temperature=0)

structured_llm.invoke("Tell me a joke about cats.
Make sure to call the Joke function.")

C s@ t | }|ptt}tdd}t|}t||||||d} | S )a Creates a chain that extracts information from a passage.
Args:
schema: The schema of the entities to extract.
llm: The language model to use.
prompt: The prompt to use for extraction.
verbose: Whether to run in verbose mode. In verbose mode, some intermediate
logs will be printed to the console. Defaults to the global `verbose` value,
accessible via `langchain.globals.get_verbose()`.
Returns:
Chain that can be used to extract information from a passage.
