- OpenAI rolled out two versions of GPT-Live: GPT-Live-1, which powers ChatGPT Voice for Go, Plus, and Pro users, and GPT-Live-1 mini, the default for free users.
- GPT-Live is built on a full-duplex architecture that allows the models to listen and speak at the same time, per cross-coverage of the launch.
Why it matters: OpenAI is splitting its new voice stack into a paid flagship (GPT-Live-1) and a lighter free-tier model (GPT-Live-1 mini), giving paying users the full-duplex capability while free users get a downgraded default — a familiar freemium pattern that gates the most advanced experience behind a subscription.
