Context & Analysis

Grok Voice 3.0 is the latest version of the speech-to-speech model behind SpaceXSI's Voice Agent API, and it lands at the same price as its predecessor, Grok Voice 2.0, with developers pointing at the grok-voice-latest alias already moved over without changes.

The company, formerly xAI, has been renamed twice recently: SpaceX acquired xAI in February, the AI unit became SpaceXAI in July, and it took on the SpaceXSI name earlier this month. Its voice technology is already in production at Tesla and Starlink, which gives SpaceXSI real-world volume to draw on.

Beyond Artificial Analysis' index, Grok Voice 3.0 also led for accuracy on ServiceNow's open-source EVA-Bench, scoring 74% across more than 200 enterprise scenarios, with a ServiceNow senior director saying the model pairs top accuracy with a natural, responsive conversation.
