When to use GPT Realtime Translate

Updated 2026-07-31

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

The model accepts raw audio input and returns translated audio output without intermediate text conversion. It supports voice cloning across 13 languages: Spanish, Portuguese, French, Japanese, Russian, Chinese, German, Korean, Hindi, Indonesian, Vietnamese, Italian, and English.

On Kyma, it operates as a realtime websocket connection billed per minute. Requests automatically failover if a serving path degrades, and every response includes the exact cost in usage.cost alongside an X-Kyma-Model header. Prompt caching bills repeated prompt prefixes at 10% of the input rate.

It is strictly an audio modality model with a 3600-token context window. It does not support text inputs, vision, structured outputs, or explicit reasoning steps, and runs on a premium cost tier with fast inference speeds.
