GPT Live 1 Astra
Product
by OpenAI
GPT-Live-1 is OpenAI’s full-duplex voice model for API applications, enabling natural, real-time conversations in which it listens and speaks simultaneously while handling interruptions, pauses, and backchannels. “Astra” refers to the backend reasoning model configuration used with GPT-Live-1, rather than a separate standalone product; the system can delegate deeper reasoning and tool calls to a backend model such as GPT-6 Astra.
