IMPORTANT: In July 2025, we stopped releasing new versions of KTX modules, and we removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the previously released KTX modules, we recommend that you migrate your app to use KTX APIs from the main modules instead. For details, see the FAQ about this initiative.

auto

public static final @NonNull FunctionCallingConfig auto()

The default behavior for function calling. The model calls functions to answer queries at its discretion.

none

public static final @NonNull FunctionCallingConfig none()
