Gemini 2.5 Pro TTS

Text-to-speech model: text in, audio out. RECORDED EXACTLY AS GOOGLE STATES IT, because the two things it states do not agree: the deprecations row is GRAY (= already shut down) and its Shutdown date cell reads "No shutdown date announced", while the pricing page still carries a rate card (input $1.00 text, output $20.00 audio; batch $0.50 / $10.00) with the free tier marked "Not available". Status follows the gray marker, which is the page's own legend; retires_on stays null because no date is published. 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 marks already-shut-down models with a gray row on the deprecations table ("Already-shutdown models are indicated with gray backgrounds"), and this row is gray, so status is retired. 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. Lifecycle read first-party from Google's deprecations table on 2026-08-19.
