Key points

  1. SpaceXSI says Grok Voice 3.0 is available in its Voice Agent API at $0.08 per minute, the same as Grok Voice 2.0, and agents on grok-voice-latest were switched over automatically.
  2. SpaceXSI reports that Artificial Analysis ranks it first on the Speech-to-Speech Index at 86.9, ahead of GPT-Live-1 at 83.2 and Gemini 3.8 Live at 82.6.
  3. SpaceXSI says Starlink call centres use Grok Voice to answer 20,000 customer calls every day, and roughly 70% are resolved with no human in the loop.

What happened

SpaceXSI announced Grok Voice 3.0, a speech-to-speech model, on 14 October 2026. It is available in the Voice Agent API at $0.08 per minute, the same price as Grok Voice 2.0, and agents using grok-voice-latest were switched over automatically.

SpaceXSI says Artificial Analysis's independent testing ranks it first on its Speech-to-Speech Index with 86.9, ahead of GPT-Live-1 at 83.2 and Gemini 3.8 Live at 82.6. It reports a tau-Voice score of 71.6%, against 74.5% for GPT-Live-1 (Astra, Medium).

On Artificial Analysis's Big Bench Audio run it lists a cost per task of $0.025 for Grok Voice 3.0, against $0.030 for GPT-Live-1 and $0.055 for GPT-Realtime-2.1. The company says Starlink call centres use Grok Voice to answer 20,000 customer calls every day and that roughly 70% are resolved without a human.

What it means for you

Our view

The benchmark figures are SpaceXSI's account of Artificial Analysis's results, and the Starlink call figures are the company's own, so none is an independent finding of ours.

The price stays at $0.08 a minute, and because agents on grok-voice-latest were switched over automatically, their behaviour can change without any action on your side.

If you run voice agents on this API, pin a model version where the API allows it, replay a sample of your own calls against 3.0 before relying on it, and compare your cost per call, not only the per-minute rate.

It adds no new facts.
