What happened
xAI released Grok Voice 3.0 on the 14th and opened it through the Grok Voice API at $0.08 per minute ($4.80 per hour), unchanged from the previous model.
Why it matters
The model is pitched for voice AI agents that handle conversations in customer support and sales, and it supports more than 25 languages, so businesses weighing voice agents now have another option at a flat per-minute price.
WHO IT HITSCompanies building voice AI agents for customer support and sales — and the developers wiring them into external tools — get another priced option, since the API can run searches, check schedules and make bookings from a conversation.

xAI is opening Grok Voice 3.0 through the same API slot as before, and its pricing of $0.08 per minute ($4.80 per hour) is unchanged from the previous model. That means existing developers who point at "grok-voice-latest" are switched to the new model without changing their code.
The model is positioned not just as a conversational voice but as a voice AI agent. Beyond natural back-and-forth — handling pauses, speaker changes and interruptions, and working in noisy or accented conditions — the Grok Voice API can connect to external services and tools to search for information, check schedules and make bookings. That points to use in customer support and sales, where the agent completes a task rather than only answering a question.
Grok Voice is already handling voice interactions in Tesla vehicles and in the Starlink call center, which suggests the technology is in real operational use ahead of this release. The new version extends that base with support for more than 25 languages.
