Live — preview since I/O, on OpenRouter; deprecated by Google Oct 8: no longer selectable in AI Studio, API requests to gemini-3.5-flash auto-route to gemini-3.6-flash, and the endpoint is not shutting down (Gemini API changelog + deprecations page, read Oct 26). On the board as live since 2026-05-19 — the watchers keep tracking it: lineup changes, pricing moves and deprecations all alert.
