Haofan Zhang updated the Jupyter AI extension in the jupyterlab/jupyter-ai repository to support the latest Gemini models, specifically adding gemini-2.5-pro and gemini-2.5-flash while removing deprecated versions. This work focused on backend development and API integration using Python, ensuring the extension aligned with the evolving Gemini model roadmap. By refreshing the supported model list, Haofan enabled users to access new capabilities within their Jupyter AI workflows. The targeted update was implemented with minimal code changes to reduce risk and maintain clear release traceability, reflecting a focused and incremental approach to feature delivery within a short timeframe.
