Introducing GPT‑Live

OpenAI upgraded the model powering ChatGPT's voice mode to a new version called GPT-Live that can delegate complex tasks to GPT-5.5 while maintaining conversation flow. The previous voice mode used a GPT-4o era model with a knowledge cutoff in 2024, whereas GPT-Live will use GPT-5.5 at launch and update automatically as newer models are released. Users can now use voice mode for more complex reasoning and web search tasks without interrupting the natural back-and-forth conversation.
