gemini-1.0-flash
Gemini 1.0 Flash (Google)
Yes — Gemini 1.0 Flash is retired and no longer served by Google, which has not published the exact shutdown date. The recommended replacement is Gemini 2.5 Flash.
The low-latency tier of the first Gemini generation, and the start of the Flash naming that Google still uses. Like 1.0 Pro it left the API without a published retirement date, which is why this page carries a status but no shutdown day.

What to use instead
