xAI launches Grok Voice 3.0, topping speech-to-speech benchmarks

By PulseAugur Editorial · [1 sources] ·

xAI has launched Grok Voice 3.0, a new speech-to-speech model that now powers the grok-voice-latest alias, automatically upgrading users without requiring any configuration changes. This new model has achieved a score of 86.9 on the Artificial Analysis Speech to Speech Index, surpassing OpenAI's GPT-Live-1 at 83.2.

IMPACT Sets a new benchmark for speech-to-speech models, potentially pressuring competitors like OpenAI and highlighting the importance of latency in voice agent performance.
