Overview

GPT-Live-1 is OpenAI's new generation of conversational models, launched on 8 July 2026 to replace Advanced Voice Mode in ChatGPT. The model introduces a full-duplex architecture: it processes input and generates output simultaneously, deciding to speak, listen, pause or interrupt many times per second. Users can interject and trail off without the rigid turn-taking rhythm of earlier voice interfaces. A key architectural element is the separation between the voice model and the reasoning model: when a question requires web search or deeper reasoning, GPT-Live-1 delegates it to GPT-5.5 running in the background while keeping the conversation going. GPT-Live-1 is the default for the paid Go, Plus and Pro tiers. At launch it does not support video or screen sharing, and some languages (e.g. Hindi in the demo) sound artificial.
