#GPT-Live

OpenAI introduced GPT-Live, a new family of voice models for ChatGPT that enables full-duplex conversation and can delegate complex tasks to GPT-5.5. Two versions are available: GPT-Live-1 for paid users and GPT-Live-1 mini as the default for all users, replacing Advanced Voice Mode. This upgrade significantly enhances ChatGPT voice mode by using a more capable model and seamless task offloading, improving user experience for complex queries. It demonstrates practical progress in conversational AI, making voice assistants more useful for brainstorming and multi-step tasks. GPT-Live uses a full-duplex architecture that can listen and speak simultaneously, maintaining natural conversation flow. It delegates web search, deeper reasoning, and other complex work to OpenAI's latest frontier model GPT-5.5, and OpenAI will continuously update the background model. The larger GPT-Live-1 model is available on paid plans, while GPT-Live-1 mini is free.
