OpenAImodelGPT-Live-1 in the API
OpenAI's voice model that can listen and talk at the same time is now available to developers building voice agents, at $0.05 per minute.
Details
- The model listens while it speaks, so callers can interrupt the way they would with a person
- Hands deeper reasoning and tool calls to a backend model you choose, such as GPT-6 Astra, which is billed separately
- Costs $0.05 per minute of voice session, billed per second
- Launches with 12 voices across accents, dialects, and languages. Custom voices require contacting OpenAI sales
- Takes audio and text in and out, with no image or video. Not available on the free API tier
Best for
Phone and in-app voice agents that need natural back-and-forth, including callers cutting in mid-sentence
When to use it
Your current voice agent feels stiff because it waits for the caller to finish before it can respond.
Who benefits
Developers building customer support, booking, or sales voice agents
