Gemini 2.5 Flash TTS

Preview

Text-to-speech model: text in, audio out. Input $0.50 (text), output $10.00 (audio); batch $0.25 / $5.00. Google states "No shutdown date announced" but names gemini-3.1-flash-tts-preview as the recommended replacement, so the pointer is recorded and the status stays preview. 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.

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 in preview.
