During February 2025, Zhongzhen focused on stabilizing the infiniflow/ragflow repository’s Python SDK by addressing a critical bug affecting session handling. He improved the session.ask method to return a single message when stream was set to False, ensuring the SDK’s behavior matched the documented API and eliminating inconsistent response formats that previously caused integration confusion. This work, implemented in Python and leveraging his skills in SDK development and bug fixing, enhanced the usability and reliability of non-streaming calls for downstream developers. Although no new features were added, Zhongzhen’s targeted fix contributed to a more predictable and developer-friendly SDK experience.
