OpenAI introducing GPT‑Live voice models in ChatGPT

We’re launching GPT‑Live, a new generation of voice models that make talking with AI feel much more like having a real conversation.

GPT‑Live is built on a full-duplex architecture, meaning it can listen and speak at the same time. During conversations, GPT‑Live can show it’s paying attention with phrases like “mhmm” or “yeah”, engage in quick back-and-forth, or just stay quiet when you need a moment to think. The result is a voice experience that is refreshingly easy to talk to.

GPT‑Live is also our smartest voice model yet. For questions that require web search, deeper reasoning, or more complex work, it delegates to our latest frontier model behind the scenes and brings the result back into the conversation when it’s ready. While it works, GPT‑Live can keep talking with you and maintain the flow of conversation. At launch, GPT‑Live will use GPT‑5.5 in the background. As we release new frontier models, we’ll continuously update the model used by GPT‑Live.

These advances power a new ChatGPT Voice experience that is more intelligent and natural to use. Over time, we believe this research will also unlock the ability to use voice for increasingly complex, longer-running, and more agentic work.

We’re beginning to roll out two versions of GPT‑Live – GPT‑Live‑1 and GPT‑Live‑1 mini – to ChatGPT users globally today. We also plan to bring them to the API soon, and developers and enterprises can sign up to be notified using this form⁠.

Availability & limitations​

GPT‑Live is rolling out now to ChatGPT users globally across iOS, Android, and ChatGPT.com⁠(opens in a new window). GPT‑Live‑1 will become the default model powering ChatGPT Voice for Go, Plus, and Pro users, and GPT‑Live‑1 mini will become the default for Free users. More availability details can be found in our Help Center⁠(opens in a new window).

We’ve optimized GPT‑Live for some of the most popular languages in ChatGPT. For certain languages, the model may have a non-native accent or gaps in fluency. We’re actively working to improve the experience across languages.

At launch, GPT‑Live will not support voice with video or screen sharing in ChatGPT, but we’re working to introduce these capabilities soon. You can still access legacy versions of ChatGPT Voice, including Standard and Advanced Voice Mode, where these features are available.
