OpenAI launched GPT-Live on July 8, 2026 — a genuine architectural overhaul of its voice interface, not just a rebrand. This episode breaks down what changed, what shipped, and what's still unconfirmed.

- GPT-Live is the official product name replacing ChatGPT's Advanced Voice Mode, shipping in two tiers: GPT-Live-1 for paid users and GPT-Live-1 mini for free users
- The core architectural shift is full-duplex audio — the model can listen and speak simultaneously, replacing the prior walkie-talkie-style turn-taking
- Users can interrupt mid-sentence for the first time, and real-time web search is now integrated into voice sessions
- On the API side, OpenAI also shipped GPT-Realtime-2 and GPT-Realtime-Translate (live translation across 70+ languages) in the same announcement cycle
- GPT-Live is a voice interface layer, not a new base model — it is functionally distinct from GPT-5.6, which launched the same day
- Key open questions remain: which backend model GPT-Live actually routes to is disputed across sources, and benchmark figures cited by one outlet are unconfirmed pending a primary source
