Google deprecates Gemini 3.7 Flash, auto-routes requests to Gemini 3.8 Flash
2026-10-08
Google's Gemini API changelog (Oct 8, 2026) announced gemini-3.7-flash is deprecated and replaced by gemini-3.8-flash, with all requests to the old model string automatically routed to the new one; developers are told to update their model string. The same entry announced the deep-research-pro-preview-12-2025 agent is deprecated and will shut down October 23, 2026, with migration to newer Deep Research agent variants.
Significance 2: Routine model-lifecycle churn on a tracked entity with automatic routing and no new capability or score reported — context-level per the rubric.
