Gemini 2.5 Pro TTS

Deprecated

Text-to-speech model: text in, audio out. Pricing page rate card: input $1.00 text, output $20.00 audio; batch $0.50 / $10.00, free tier "Not available". GREY MARKER REMOVED 2026-10-07: on that read the deprecations row is no longer grey and its Shutdown date cell reads November 17, 2026, so Google now states the endpoint is running with a published shutdown date; status is deprecated and retires_on carries that date. Until 2026-10-06 the row was held at retired, on the grey marker: the row was GRAY (the page's own legend for "already shut down") while its Shutdown date cell read "No shutdown date announced" and the pricing page kept the rate card - two statements that did not agree, recorded as Google stated them. The still-published rates ARE carried in the price fields, the same way gemini-2.5-flash-lite-preview-09-2025 is handled: a rate Google is still publishing is a fact, and a consumer who wants only sellable models filters on status. Google states the listed shutdown dates are "the earliest possible dates on which a model might be retired". Google's current models page publishes no input/output token limits for this endpoint (read 2026-08-19), so context_window and max_output_tokens are null rather than carried over from a page that no longer states them. Until 2026-09-24 the row named gemini-3.1-flash-tts-preview as the recommended replacement; by the 2026-09-25 read it names 'gemini-3.8-flash-tts or gemini-3.8-flash-lite-tts', and the replacement field carries the first-named. Lifecycle read first-party from Google's deprecations table on 2026-08-19, re-read 2026-09-25 and 2026-10-07.

Gemini 2.5 Pro TTS by Google costs $1 per 1M input tokens and $20 per 1M output tokens ($5.75/1M blended). It is deprecated, shutting down 17 Nov 2026; the recommended replacement is Gemini 3.8 Flash TTS.
