OpenAI has published a technical overview of the real-time system powering GPT-Live, its latest voice interaction platform. Unlike traditional turn-based assistants, GPT-Live continuously streams incoming audio while simultaneously generating spoken responses through a full-duplex architecture.
The system separates conversational speech from deeper reasoning, allowing complex tasks such as web search and tool use to run asynchronously without interrupting the conversation.
OpenAI says this design reduces latency, improves responsiveness, and enables more natural interactions while scaling efficiently across millions of users. The architecture forms the foundation for ChatGPT Voice today and future GPT-Live API experiences.
