AI Gateway now supports streaming transcription
Why it matters
Vercel's AI Gateway adds streaming transcription in beta, enabling real-time voice-to-text for live captioning and voice agents with sub-second latency. This lowers the friction for building conversational AI products and agent voice modes across OpenAI, Anthropic, and xAI models.
Key signals
- Streaming transcription now beta on AI Gateway
- Works with OpenAI GPT-realtime-whisper, Anthropic, xAI Grok-STT, and other streaming-capable models
- Enables live captioning and voice agent input with reduced latency
- Available via AI SDK streamTranscribe function
- Returns partial and final transcript deltas in real-time
- Allows voice mode for text-based agents without agent code changes
- Works across multiple providers with single model string swap
