 ** *`model_size_bytes` (Optional, number)*: The estimated memory usage in bytes to keep the trained model in memory.
 This property is supported only if defer_definition_decompression is true
 or the model definition is not supplied.
+** *`platform_architecture` (Optional, string)*: The platform architecture (if applicable) of the trained mode. If the model
+only works on one platform, because it is heavily optimized for a particular

+architecture or OS features), leave this field unset.
 ** *`tags` (Optional, string[])*: An array of tags to organize the model.
 ** *`defer_definition_decompression` (Optional, boolean)*: If set to `true` and a `compressed_definition` is provided, the request defers definition decompression and skips relevant validations.
