What Is GPT-Red? OpenAI Built an AI Hacker to Attack Its Own Models

TL;DR: GPT-Red in 30 Seconds GPT-Red is an automated red-teaming model OpenAI trained to break its own models; it is not public and never will be. It was trained with self-play: attacker GPT-Red and defender models played against each other, both getting stronger over time. In scenarios where human red-teamers succeeded only 13% of the time, GPT-Red hit 84%. GPT-5.6 was trained against GPT-Red, making it OpenAI’s most robust model against prompt injections (only a 0.05% failure rate). OpenAI just announced something unusual: not a model for users, but an “AI hacker” trained to break its own models. Meet GPT-Red! According to the research publication “Unlocking Self-Improvement for Robustness” released today, GPT-Red automates the work of human security testers (red teams) and does it far better than humans. ...

What Is GPT-Live? The AI That Listens While It Speaks

Talking to AI no longer feels like a walkie-talkie exchange, it finally feels like a real conversation! On July 8, 2026, OpenAI announced GPT-Live, its next-generation family of voice AI models. This is not just a better voice mode, it is an architectural shift that redefines the voice AI experience. So what makes GPT-Live so different? Let’s dive in. What Is GPT-Live? GPT-Live is OpenAI’s new voice model family built on a full-duplex architecture. Full-duplex means the model can listen and speak at the same time. With the previous Advanced Voice Mode, the model waited while you spoke and you waited while it spoke. GPT-Live removes that turn-taking constraint entirely. ...
