OpenAI Launches GPT-Live-1 Voice Model in API
OpenAI has launched GPT-Live-1 in its API, a voice-native model designed for building voice-enabled applications and business workflows. The model handles listening and speaking simultaneously, reducing latency by eliminating the need for chained speech-to-text, reasoning, and text-to-speech components. It features improved interruption handling, background noise resilience, and the ability to delegate reasoning and tool calls to backend models like GPT-6 Astra or third-party models. The API includes telephony support for full-duplex voice agents. Pricing is set at $0.05 per minute for the voice layer, with backend models billed separately. Early evaluations show an 80% reduction in interruptions for language tutoring compared to turn-based systems.
