     Args:
         input (str | Series | List[str|Series] | Tuple[str|Series, ...]):
             A mixture of Series and string literals that specifies the input to send to the model. The Series can be BigFrames Series
             or pandas Series.
         categories (tuple[str, ...] | list[str]):
             Categories to classify the input into.
+        examples (list[tuple[str, str]], optional):
+            An array that contains representative examples of input strings and the output category
+            that you expect. You can provide examples to help the model understand your
+            intended threshold for a condition with nuanced or subjective logic. We recommend providing at most 5 examples.
         connection_id (str, optional):
             Specifies the connection to use to communicate with the model. For example, `myproject.us.myconnection`.
             If not provided, the query uses your end-user credential.
+        endpoint (str, optional):
+            A STRING value that specifies the Vertex AI endpoint to use for the model. You can specify any
+            generally available or preview Gemini model. If you specify the model name, BigQuery ML automatically
+            identifies and uses the full endpoint of the model.
+        optimization_mode (Literal["minimize_cost", "maximize_quality"], optional):
+            A STRING value that specifies the optimization strategy to use. Supported values are ``minimize_cost``
+            and ``maximize_quality``.
+        max_error_ratio (float, optional):
+            A value between ``0.0`` and ``1.0`` that contains the maximum acceptable ratio of row-level
+            inference failures to rows processed on this function. The default value is 1.0.
+            This argument isn't supported when ``optimization_mode`` is set to ``minimize_cost``.

         bigframes.series.Series: A new series of strings.
