 ### New Features and Improvements
 
+* Added support for passing additional kwargs to `WorkspaceClient().serving_endpoints.get_open_ai_client()` ([#1025](https://github.com/databricks/databricks-sdk-py/pull/1025)). Users can now pass standard OpenAI client parameters like `timeout` and `max_retries` when creating an OpenAI client for Databricks Model Serving.
