// models for the `Predict()` API. A model is queried
// indirectly via a ServingConfig, which associates a model with a
// given Placement (e.g. Frequently Bought Together on Home Page).

//
// * Initiate training of a model.
// * Pause training of an existing model.
// * List all the available models along with their metadata.
// * Control their tuning schedule.
