OpenAI Launches GPT-Live: GPT-Live-1 and GPT-Live-1 Mini Replace Advanced Voice Mode Globally on July 8 With Real-Time Translation, Natural Interruption and GPT-5.5 as the Reasoning Backend
OpenAI on Wednesday launched GPT-Live, a new family of voice models capable of listening and speaking simultaneously in real time. The company is replacing its current Advanced Voice Mode in ChatGPT with GPT-Live-1 mini by default, while users on paid tiers will be able to access the larger GPT-Live-1 model.

GPT-Live uses a full-duplex architecture that processes input and generates output continuously, rather than waiting for a speaker to finish a turn, making it possible for the model to interrupt, search the web, or perform other tasks while the conversation continues. The model makes interaction decisions many times per second, whether to speak, keep listening, pause, or call a tool.
The previous model combined a speech-to-text model to transcribe speech, a large language model to generate responses, and a text-to-speech model to deliver the final answer. The new architecture enables features like live translation and lets the model acknowledge a speaker mid-sentence with cues like “mhmm” rather than waiting for a full turn to end.
GPT-Live delegates web search, reasoning, or complex work to GPT-5.5 in the background while the conversation keeps flowing. More than 150 million people talk to ChatGPT each week using voice and dictation features.
The launch has real gaps; during a live demo of the translation feature in Hindi, the assistant spoke with a heavy American accent and an unnatural tone. GPT-Live also does not support voice with video or screen sharing at launch, with legacy Voice Mode still available for those features.
The phone call has been the primary interface between humans and remote services for a century. GPT-Live is OpenAI’s most direct bid to replace it, not with a chatbot, but with something that sounds, responds and interrupts like a person.
