Gemini 2.5 Flash

Deprecated

Output: text only. Audio input priced higher: input $0.30 (text/image/video) / $1.00 (audio); cached input $0.03 (text/image/video) / $0.10 (audio) per 1M tokens (values shown are text/image/video tier). DEPRECATED 2026-11-02, per Google: the Gemini API changelog entry dated November 2, 2026 says "gemini-2.5-flash is deprecated and is no longer available to select in Google AI Studio. Effective December 1, 2026, all API requests to gemini-2.5-flash will automatically route to gemini-3.5-flash-lite and be billed at Gemini 3.5 Flash-Lite rates." The deprecations table row for gemini-2.5-flash now gives shutdown December 1, 2026 and gemini-3.5-flash-lite as the recommended replacement, under a caution callout repeating the same text, and the model page links to it and says API access is limited to existing users until December 1, 2026. Signal used: Google's own dated deprecation declaration on those three surfaces, read first-party on 2026-11-03 (the docs now redirect from ai.google.dev to aistudio.google.com/docs); NOT a grey row and not a passed date, and nothing here is retired. NOTE THE AUTO-ROUTE: on and after 2026-12-01 Google states that calls to this model string are served by gemini-3.5-flash-lite and billed at its rates, so the rates above stop applying then even though the string keeps answering. The same table and callout state that gemini-2.5-flash-lite "is not deprecated and remains available through the API until further notice". Previous stages, kept for the history: from 2026-10-20 to 2026-11-02 this row was held at ga because the model page said "These models are not deprecated and will continue to be served until further notice through the API" and the deprecations row read "No shutdown date announced" with no replacement; that sentence is gone from the model page as of this read. Before that, until 2026-10-19, the same table gave shutdown October 16, 2026 and gemini-3.6-flash as the recommended replacement (gemini-3.5-flash until Google re-pointed it on 2026-07-31), and the row was deprecated on that basis; that date passed without a grey marker and Google withdrew it. The pricing page still carries the section with the rates above. Deprecations page release date: 2025-06-17. Latest update June 2025.

Gemini 2.5 Flash by Google costs $0.3 per 1M input tokens and $2.50 per 1M output tokens ($0.85/1M blended), with a 1.0M (1.048.576-token) context window. It is deprecated, shutting down 1 Dec 2026; the recommended replacement is Gemini 3.5 Flash-Lite.
