By PulseAugur Editorial · [1 sources] ·

SpaceXAI has launched Grok Voice 3.0, an updated speech-to-speech model for voice agents. The new version maintains the same $0.08 per minute pricing as its predecessor, Grok Voice 2.0, and automatically updates existing agents using the 'grok-voice-latest' alias. Key improvements include under-one-second latency, a 97% Full Duplex score on the Artificial Analysis benchmark, and enhanced capabilities for support-style agents, with claims of millions of daily conversations across Tesla and SpaceX platforms. AI

IMPACT Enhances real-time voice agent capabilities, potentially improving customer support and interactive AI experiences across various platforms.
