GPT-Live 1 now available on AI Gateway

Read on vercel.com

Summary

Vercel AI Gateway now offers OpenAI’s GPT‑Live 1, a full‑duplex voice model that can listen and speak simultaneously. The SDK lets you start a voice session and optionally delegate work to any text model, with code examples for both patterns.

  • GPT‑Live 1 supports full‑duplex audio, allowing the model to listen and speak at the same time.
  • Client delegation lets your app invoke any text model while the voice session continues, with separate billing.
  • Install AI SDK 7 and @ai-sdk/openai 4.0.67+, then use `experimental_realtime('openai/gpt-live-1', {api:'live'})` to start a session.
  • Send a `context-append` event with a delegationId to feed text model output back to the voice model on the “commentary” channel.

Developers building voice assistants on Vercel AI Gateway can now use full‑duplex GPT‑Live 1 and delegate to text models for richer interactions.
