Deprecated in favor of tool_choice. Controls which (if any) function is called by the model. none means the model will not call a function and instead generates a message. auto means the model can pick between generating a message or calling a function. Specifying a particular function via {\"name\": \"my_function\"} forces the model to call that function. none is the default when no functions are present. `auto`` is the default if functions are present.
