Grok Voice Think Fast 2.0 available on AI Gateway
Grok Voice Think Fast 2.0, a speech-to-speech voice model from xAI, is now available on AI Gateway with improved reasoning, transcription accuracy, and lower latency for tool calls. The model reasons in parallel with speech and handles real-world audio conditions including background noise and telephony compression.
is now available on AI Gateway. It is a speech-to-speech voice model that takes audio in and audio out, improving on the previous Grok Voice model in reasoning, transcription accuracy, and conversation.Grok Voice Think Fast 2.0 from xAI
The model reasons in parallel with speech, so it can think through a query while talking without adding latency. It has also been trained to use fewer reasoning tokens than before, so tool calls fire sooner, often before the end of the agent's first sentence. Transcription holds up in real-world conditions, including background noise and telephony compression.
Use through the AI SDK's realtime API. Mint a short-lived token on the server so your API key never reaches the client:xai/grok-voice-think-fast-2.0
