Grok Voice 3.0 ranks first on the Speech-to-Speech Index by Artificial Analysis
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.

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 0.030 for GPT-Live-1 and $0.055 for GPT-Realtime-2.1 (High).
