[GPT-Live 1 from OpenAI](https://vercel.com/ai-gateway/models/gpt-live-1) is now available on AI Gateway. 

GPT-Live 1 is a full-duplex voice model and can listen and speak at the same time. Many voice models use turn detection to respond. Full duplex removes that boundary, so a user can pause, interrupt, or add detail while GPT-Live is speaking.

GPT-Live 1 also supports client delegation. Client delegation lets you choose the background model independently from GPT-Live 1. A basic session runs only the voice model. When deeper work is needed, your application can handle `delegation-created` with [any text model on AI Gateway](https://vercel.com/ai-gateway/models?type=text) while the conversation continues.

Install AI SDK 7, `@ai-sdk/openai 4.0.67` or later, and a WebSocket client:

This starts `openai/gpt-live-1` without calling another model. Wait for `session-started` before sending audio.

You can call a text model for GPT Live to delegate to, then return the result on the `commentary` channel for it to speak. This example uses `openai/gpt-5.6-sol`, but you can substitute any text model available on AI Gateway:

Your application controls delegated work and its permissions, confirmations, and cancellation. Delegated model requests are billed separately through AI Gateway; voice-session usage continues while they run. These snippets omit WebSocket connection, event parsing, transcript assembly, audio streaming, and shutdown. See the [GPT-Live guide](https://vercel.com/docs/ai-gateway/modalities/realtime/gpt-live) in the AI Gateway docs for connection setup, audio streaming, and complete examples. For all audio models on AI Gateway, go to the [model list](https://vercel.com/ai-gateway/models?modality=audio).
