xAI launched Grok Voice 3.0, topping Artificial Analysis's Speech-to-Speech Index at 86.9 (vs GPT-Live-1's 83.2), with the biggest gains on τ-Voice tool-use tasks like rebooking flights and disputing charges. It also leads ServiceNow's EVA-Bench for enterprise voice agents at 74% accuracy, best on combined accuracy + customer experience.
Pricing is a flat $0.08/minute regardless of reasoning effort, while OpenAI's token billing nearly doubles when GPT-Realtime-2.1 runs at High effort — per-task cost $0.025 vs $0.055, a tangible advantage for heavy voice workloads.
