  "details": "Google shuts down gemini-2.5-flash-preview-tts and gemini-2.5-pro-preview-tts on 2026-11-17. After that the models are turned off and speech-generation calls that name them in the path fail. Calls that pass the model in a request body are not matched by this path.\n\nSwitch to gemini-3.8-flash-tts or gemini-3.8-flash-lite-tts before 2026-11-17; the current speech-generation docs send the model in the body of POST /v1beta/interactions. Re-check voice names and how you decode the returned audio.",
