Yes, there is an

exclude_function_call

argument in the

.copy()

method for

chat_ctx

in LiveKit. The method signature is:

def copy(
    self,
    *,
    exclude_function_call: bool = False,
    exclude_instructions: bool = False,
    exclude_empty_message: bool = False,
    tools: NotGivenOr[Sequence[FunctionTool | RawFunctionTool | str | Any]] = NOT_GIVEN,
) -> ChatContext:

When

exclude_function_call=True

, the method excludes items with type "function_call" and "function_call_output" from the copied context. By default, this parameter is set to

False

, meaning function calls are included unless explicitly excluded. This parameter is often used in scenarios like: • Excluding function calls when reconnecting in the OpenAI Realtime API. • Copying chat context between agents while excluding function call history.
