OpenAI releases GPT-Live and GPT-Live-1 mini voice models

OpenAI launched GPT-Live, a full-duplex voice model family that can listen and speak at the same time for more natural conversations.

It delegates web search and deeper reasoning to GPT-5.5 in the background while keeping the conversation flowing.

Two versions are rolling out globally on iOS, Android, and ChatGPT.com: GPT-Live-1 for paid tiers and GPT-Live-1 mini for free users.
