Introducing GPT‑Live

OpenAI launches GPT-Live, a new real-time voice mode for ChatGPT powered by an updated model that transparently delegates complex tasks to GPT-5.5 in the background while maintaining conversational flow.

Claims
- GPT-Live replaces the previous GPT-4o-era voice model, which had a knowledge cutoff in 2024 and was widely seen as too weak for substantive use.
- GPT-Live delegates tasks requiring web search, deeper reasoning, or complex work to GPT-5.5 in the background and returns results without breaking the conversation.
- Simon Willison used the preview version for hour-long conversations, finding it a credible brainstorming partner.
- A bug during the preview period caused the model to interrupt users with laughter at non-humorous statements; OpenAI reduced the behavior after a bug report.
Key quotes
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.
I had mostly stopped using voice mode because the age and relative weakness of the model greatly limited how useful it was as a brainstorming partner.
