The gemini-live engine on Wixzel Voice: Gemini Live, native audio
One model for the whole turn. Google Gemini Live takes the caller's audio in and produces audio out with the reasoning inside the provider, so there is no separate speech-to-text or text-to-speech stage to name and latency is what the model itself delivers.

What does each model in the gemini-live engine cost on Wixzel Voice?
A realtime engine hands the whole turn to one model, so the price is mostly that model’s units. The pipeline label is Gemini Live, native audio.
| Stage | Model | Unit price | Per minute |
|---|---|---|---|
| Realtime model | google/gemini-live | $0.0042 per 1k audio tokens in | $0.0063 |
| Realtime model | google/gemini-live | $0.0168 per 1k audio tokens out | $0.0252 |
| Realtime model | google/gemini-live | $0.0010 per 1k tokens in | $0.0025 |
| Realtime model | google/gemini-live | $0.0063 per 1k tokens out | $0.0030 |
| Orchestration | wixzel/orchestration | $0.0120 per minute | $0.0120 |
Rounded up, never down. Where two models are listed for one stage the engine picks by language; the engine price above assumes the dearer path. All prices on the model price list.
