xAI's new voice model takes over customer service
xAI just released Grok Voice 3.0, taking the #1 spot on Artificial Analysis's Speech-to-Speech Index with an 86.9 score. The model hits sub-one-second latency, undercuts competitors on task costs, and already resolves roughly 70% of Starlink's 20,000 daily support calls without a human. It's a clear signal that voice agents are graduating from novelty to high-volume enterprise infrastructure.
