Release Date

Announced and made available in the API on 2026-10-14. Existing users of the rolling alias were switched automatically; the vendor says pricing is unchanged from Grok Voice 2.0. (source)

Benchmarks

The vendor reproduces Artificial Analysis results dated 2026-10-13: AA Speech-to-Speech Index 86.9, Big Bench Audio 98.5%, Task Success Rate 94.8%, and Full Duplex Bench 97.0%. It separately reports τ-Voice 71.6% and EVA-Bench accuracy 74%. These are different metrics, not interchangeable success rates. The independent evaluator pages were not read in this capture.

Use Cases

Speech-to-speech support agents and hands-free tool use. The vendor describes Starlink agents verifying customers, troubleshooting hardware, issuing credits and shipping replacement equipment; these are deployment claims rather than an independently audited reliability study. (source)

Compared To

The announcement quotes AA Speech-to-Speech Index 81.3 for Grok Voice 2.0, 83.2 for GPT-Live-1 (Astra, Medium), and 82.6 for Gemini 3.8 Live (Ext. Thinking, High). Preserve those effort settings and the evaluation date when comparing. Its stated 40% lower latency than GPT-Live-1 on τ-Voice is not a claim of 40% higher task success. (source)
