Gemini 3.7 Flash Explained: Deprecated, Now Routed to 3.8 Flash
In short: Gemini 3.7 Flash is a Google AI model released on 13 August 2026 and since deprecated. Google's API now automatically routes requests for gemini-3.7-flash to its replacement, Gemini 3.8 Flash, and the old model can no longer be selected in Google AI Studio. While it was current, it had a 1,048,576-token context window, 65,536 tokens of output and accepted text, images, video, audio and PDFs.
What was Gemini 3.7 Flash?
Gemini 3.7 Flash was a model in Google's Flash line - the faster, lower-cost Gemini models. Google announced it in August 2026, about three weeks after Gemini 3.6 Flash. Google's Pro and Flash lines are two sizes of the same family; see Gemini 3.1 Pro explained for the Pro side.

Is Gemini 3.7 Flash still available?
Its API endpoint still answers, but it is deprecated and serves a different model. Google's deprecations page lists gemini-3.7-flash (released 13 August 2026) with gemini-3.8-flash as its replacement, and notes that it is not available to select in Google AI Studio and that the endpoint is not shutting down but automatically routes API requests to gemini-3.8-flash.
In practice, code that still calls gemini-3.7-flash keeps working, but the answers now come from Gemini 3.8 Flash, released on 2 September 2026.
How much does Gemini Flash cost now?
Requests are served by Gemini 3.8 Flash, so its pricing is the one that applies. Gemini 3.8 Flash costs $0.75 per million input tokens and $3.75 per million output tokens, with a 1M-token context window; full details are on its model page and Google's pricing page.
