## Summary

xAI launched **Grok Voice 3.0**, a speech-to-speech model for voice agents, on October 14, 2026. The model is available via the **Voice Agent API** at **$0.08 per minute**—the same price as its predecessor—claiming top scores on **Artificial Analysis’ Speech-to-Speech Index (86.9)** and **ServiceNow’s EVA-Bench (74% accuracy)**. xAI says it powers **millions of daily conversations** in **Tesla vehicles** (hands-free tasks like scheduling) and **Starlink call centers** (20,000 calls/day, 70% resolved without human intervention), with **40% lower latency** than competitors like **GPT-Live-1 (Astra)** on simulated support calls.

The model’s benchmarks include **98.5% on Big Bench Audio** (speech reasoning), a **94.8% task success rate**, and **97.0% on Full Duplex Bench** (handling interruptions). xAI’s figures for **Grok Voice 2.0** show declines in most areas, while **GPT-Live-1 (Astra)** and **Gemini 3.8 Live** trail in both cost and performance. Deployment at **Tesla** and **SpaceX** (via **Grok Bot**) highlights real-world use cases, though xAI did not disclose customer counts beyond Starlink’s 20,000 daily calls. The update is **automatic** for existing API users under the `grok-voice-latest` tag.

## Key points

- Grok Voice 3.0 scores 86.9 on Artificial Analysis’ Speech-to-Speech Index, ahead of GPT-Live-1 (83.2) and Gemini 3.8 Live (82.6)
- xAI claims 40% lower latency than competitors on simulated support calls, with 70% of Starlink calls resolved without human help
- Pricing remains $0.08/minute (same as Grok Voice 2.0), and deployment at Tesla/Starlink shows real-world adoption

## Why it matters

Grok Voice 3.0’s benchmarks and cost efficiency could shift voice-agent adoption, especially for customer support and enterprise use. Its performance on **EVA-Bench** and **tau-Voice** suggests it may appeal to companies prioritizing both accuracy and conversational quality over raw model size.
