Questions
About Gemini 3.1 Flash TTS on OSMEXO
- Is this the same Gemini 3.1 Flash TTS as calling Google directly?
- Yes. Routes are checked with a real generation before they are enabled and re-checked continuously; a provider that fails or drifts is removed from rotation. Media models are verified by output, not by token fingerprint.
- How do I call Gemini 3.1 Flash TTS with the OpenAI SDK?
- Use the OpenAI-compatible audio endpoints at https://api.osmexo.com/v1 with your OSMEXO key and the model id google/tts-gemini-3-1-flash. The model page in the dashboard shows the exact request shape and lets you run one in the playground first.
- Why is Gemini 3.1 Flash TTS “on request”?
- The model is in the catalog but not yet enabled for every key, usually because its routes are still being verified or a vendor key is pending. Ask from the contact form or the dashboard and it is normally enabled within a business day.
