GPT-Live: Full-Duplex Voice First, Enterprise Later
OpenAI launched GPT-Live-1 and Live-1 mini for ChatGPT Voice—full-duplex listen-and-speak on consumer web/mobile; Business/Enterprise/Edu excluded at launch. Mass-user agent UX bid while governance surfaces wait.
Voice is how mass users will live with agents. Full-duplex GPT-Live is OpenAI’s bid to make ChatGPT feel less like a walkie-talkie and more like a call—while keeping enterprise out of the first cut until safety and governance catch up.
OpenAI on July 8, 2026 launched GPT‑Live, voice models built for natural, full-duplex conversation—listening and speaking at the same time. GPT‑Live‑1 and GPT‑Live‑1 mini began rolling out globally in ChatGPT Voice (web, iOS, Android in supported regions). Paid consumer tiers get Live‑1; Free gets Live‑1 mini. At launch the stack used GPT‑5.5 in the background, with continuous upgrades planned as frontier models advance.
