xAI Grok audio models now available on Vercel AI Gateway

What's new

• grok-voice-think-fast-1.0: low-latency realtime voice conversations
• grok-tts: Grok-powered text-to-speech
• grok-stt: speech-to-text transcription
• Server-side tokens: API keys protected via Gateway-issued ephemeral tokens
• Playground testing: try each model from the AI Gateway UI without code
• Unified billing and tracing: same controls as Grok text and other Gateway models

Why it matters

Teams already standardised on Grok now get a full voice stack without separate xAI plumbing. Combined with the Gateway's realtime support shipped the same day, it makes multi-provider voice agent comparisons trivial.

How to try

Add the xAI provider via AI SDK 7 and reference xai/grok-voice-think-fast-1.0, xai/grok-tts, or xai/grok-stt through the Vercel AI Gateway.
