Summary Report
GPT-Live-1 brings ChatGPT's natural back-and-forth to the API: one model listens and speaks simultaneously and hands reasoning to any backend, for five cents a minute.
- 01. Full-duplex: listens while it speaks, so interruptions and acknowledgements are handled in real time rather than turn by turn
- 02. The voice layer is a single model at $0.05 per minute; deeper reasoning and tools are delegated to the model and harness you choose
OpenAI has put GPT-Live-1, the full-duplex voice model behind ChatGPT's voice mode, into the API. It listens and speaks at the same time, handling interruptions and acknowledgements as they happen, while delegating deeper reasoning and tool calls to whichever backend model and harness you choose. Pricing is $0.05 per minute for the voice layer plus your reasoning model.
