Artificial Analysis ranks Grok Voice 3.0 first on its Speech-to-Speech Index, which it says blends spoken reasoning, simulated support calls, blind preference votes and task success. The post says Grok Voice 3.0 runs inside Tesla vehicles, handling millions of conversations a day for hands-free requests such as calendar checks and coffee orders. It also powers Grok Bot's voice mode.

Grok Voice 3.0 at work inside Tesla. it handles millions of conversations a day in Tesla. Drivers can use Connectors for simple requests like checking their calendar or answering an email, and Grok Bot for bigger tasks like ordering a coffee or booking dinner—all completely hands-free (see it on X). Grok Voice 3.0 also powers Grok Bot’s voice mode.
SpaceXAI launched Grok Voice 3.0 tops Artificial Analysis’s Speech-to-Speech Index at 86.9, beating OpenAI and Google. The index blends spoken reasoning, simulated support calls, blind preference votes and task success, where GPT-Live-1 (Astra, Medium) reaches 83.2. The largest gain comes on τ-Voice, where a simulated caller asks the model to rebook flights or dispute charges using domain tools and a policy document. There, Grok’s success rate jumped from 56.5% under Grok Voice 2.0 to 71.6%. Grok’s edge is speed: it answers 40% sooner than GPT-Live-1, whose 1.34 seconds implies roughly 0.8 seconds, slightly slower than Grok Voice 2.0’s 0.70. Introducing Grok Voice 3.0 +2 It also costs $0.025 per task on Artificial Analysis’s Big Bench Audio run, against $0.030 for GPT-Live-1 and $0.055 for GPT-Realtime-2.1 (High).
