The short answer
Google's Gemini API changelog of October 8, 2026: gemini-3.7-flash is deprecated and has been replaced by gemini-3.8-flash. It is no longer available to select in Google AI Studio, and API requests to gemini-3.7-flash are automatically routed to gemini-3.8-flash. Likewise, gemini-3.5-flash is deprecated, and API requests to it are automatically routed to gemini-3.6-flash.
What to do
- Search your code for gemini-3.7-flash and gemini-3.5-flash.
- Update your model string to gemini-3.8-flash (for 3.5 Flash: gemini-3.6-flash or gemini-3.8-flash).
Good to know
