When to use Gemini 3.5 Live Translate

Updated 2026-07-31

Where this model earns its cost — and where it doesn't.

Gemini 3.5 Live Translate is a real-time speech-to-speech model from Google. It accepts audio input and returns translated audio output, maintaining the original speaker's pitch, pacing, and intonation across more than 70 languages.

On Kyma, it runs as a WebSocket-based realtime session. Requests automatically failover if a serving path degrades, and the platform returns exact usage costs in the response payload. Prompt caching is supported, billing repeated prefixes at 10% of the standard input rate.

It does not support text input, vision, structured outputs, or reasoning. The context window is 16,384 tokens with a maximum output of 32,768 tokens. It operates on a per-minute billing mode and sits in the premium cost tier.
