Overview

GPT-Live-1 brings ChatGPT's natural, full-duplex voice conversation model to the API, launched September 10, 2026 at $0.05 per minute for the voice front-end layer. It listens and speaks at the same time, handles interruptions, pauses, and backchannels, and delegates deeper reasoning and actions to whichever model or tools it is paired with, including telephony support for full-duplex phone agents. OpenAI began rolling GPT-Live-1 and the smaller GPT-Live-1 Mini out to ChatGPT globally on July 8, 2026, with GPT-Live-1 becoming the default ChatGPT Voice model for Go, Plus, and Pro users and GPT-Live-1 Mini serving Free users. On October 15, 2026 OpenAI began rolling out GPT-Live-1.1 and a smaller GPT-Live-1.1 Quip (replacing the Mini) across ChatGPT Voice, Codex, and dots, adding 13 voices across six non-English languages plus an English voice called Bubbie and more natural accents. Per secondary coverage, API access is 'coming soon', the API model page still lists only gpt-live-1, and no benchmarks or latency figures were published; the system card reportedly shows regressions on some targeted synthetic safety prompts (sexual content, mental health, emotional reliance, gore).
