OpenAI Launches GPT-Live: Full-Duplex Voice Models for ChatGPT
OpenAI
OpenAI released GPT-Live-1 and GPT-Live-1 mini, a new generation of full-duplex voice models that can listen and speak simultaneously, replacing ChatGPT's existing voice experience. GPT-Live-1 becomes the default for paid users (Go, Plus, Pro); GPT-Live-1 mini serves free-tier users. The models emit active-listening cues, handle natural interruptions, and can delegate complex queries to GPT-5.5 in the background. Rolled out globally on iOS, Android, and ChatGPT.com on July 8; API access coming soon.
Why it matters
Full-duplex architecture closes the gap between AI voice and natural human conversation, enabling true back-and-forth rather than turn-based exchanges. Background delegation to a frontier model allows voice to handle complex, multi-step queries for the first time at scale.
Importance: 4/5
OpenAI flagship product launch replacing existing voice experience with a new model family; full-duplex is an architectural step change.
