Google's Gemini 3.7 Flash appears on GitHub before official announcement

Google's Gemini 3.7 Flash model was discovered in the company's GitHub repository, indicating it is in preparation or internal testing phase. The discovery occurred when someone inside Google attempted to add the model to the Python GenAI SDK using the Copybara tool, but the request was rejected due to naming errors. Currently, Google's official model catalog and API change logs still list Gemini 3.6 Flash, launched on July 21. Experts speculate that the new model may be in early testing phase, with launch expected soon, given the Flash series typical update schedule of approximately every two months.
