Model is constrained to always predicting function calls only.
If "allowed_function_names" are set, the predicted function calls will be
limited to any one of "allowed_function_names", else the predicted
function calls will be any one of the provided "function_declarations".
Auto
Default model behavior, model decides to predict either function calls
or natural language response.
None
Model will not predict any function calls. Model behavior is same as when
not passing any function declarations.
Unspecified
Unspecified function calling mode. This value should not be used.
