Grok Voice 3.0, at the old price

xAI announced Grok Voice 3.0 on October 14. The company calls it a speech-to-speech model with latency under one second, and says it is available in the Voice Agent API at $0.08 a minute, $4.80 an hour, the same price as Grok Voice 2.0. Agents already pointed at grok-voice-latest were switched over. No integration change, xAI says.

The benchmark xAI leads with is Artificial Analysis’s Speech-to-Speech Index. xAI dates that source October 13, 2026, and reports a score of 86.9 for Grok Voice 3.0, against 83.2 for GPT-Live-1 at its Astra medium setting and 82.6 for Gemini 3.8 Live with extended thinking set high. On the same table, xAI lists Full Duplex Bench at 97.0 percent, a task-success rate of 94.8 percent, and a speech-reasoning score, on Big Bench Audio, of 98.5 percent. On τ-Voice, the support-call test with accents, noise, and interruptions, xAI reports 71.6 percent and says that is comparable to GPT-Live-1 at 40 percent lower latency.

MODEL has not replayed those calls. The numbers are xAI’s citation of Artificial Analysis. If you are buying voice for a support line, the table is a reason to run your own calls.

Two deployment figures, again xAI’s. The company says Grok Voice handles millions of conversations a day in Tesla vehicles, including connectors for calendar and email and a mode it calls Grok Bot for tasks such as ordering or booking. It says Starlink call centers use Grok Voice for 20,000 customer calls a day, across multiple languages; that roughly 70 percent are resolved with no person in the loop; and that one in four sales calls ends in a purchase before the caller hangs up. A single agent, xAI says, verifies customers, troubleshoots hardware, issues credits, and ships replacements.

On ServiceNow’s EVA-Bench, xAI reports the highest accuracy score at 74 percent. That figure is xAI’s account of the benchmark.

The price is the cleanest fact on the page. Eight cents a minute, same as last time, live in the API now.
