Gemini 2.5 Flash TTS

Deprecated

Text-to-speech model: text in, audio out. Input $0.50 (text), output $10.00 (audio); batch $0.25 / $5.00. Until 2026-10-06 Google stated "No shutdown date announced" and the status was held at preview. On the 2026-10-07 read Google's deprecations table publishes a shutdown date of November 17, 2026 for this endpoint (row not grey, so it is still running); status is therefore deprecated and retires_on carries that date. Google publishes shutdown dates as "the earliest possible dates on which a model might be retired". Until 2026-09-24 Google's deprecations table 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', both GA since 2026-09-22. The replacement field holds one id and carries the first-named, gemini-3.8-flash-tts, in the table's own order; both are first-party migration targets. 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. Lifecycle read first-party from Google's deprecations table on 2026-08-19 and re-read 2026-09-25.

Gemini 2.5 Flash TTS by Google costs $0.5 per 1M input tokens and $10 per 1M output tokens ($2.88/1M blended). It is deprecated, shutting down 17 Nov 2026; the recommended replacement is Gemini 3.8 Flash TTS.
