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. ...

OpenAI has announced the GPT-5.6 series, reshaping the landscape of artificial intelligence! We are looking at a completely new approach to reasoning and problem-solving, not just a model update. This next generation comes in three distinct options: Sol, Terra, and Luna. What will these new models change in our lives? How are they making leaps in coding, biology, and cybersecurity? Let’s dive into the details! The GPT-5.6 Series: Sol, Terra, and Luna OpenAI introduced three models tailored to different needs: ...

OpenAI has announced GPT-5.5, its smartest and most intuitive model to date. Introduced as “a new class of intelligence,” it is poised to fundamentally change how we get work done on a computer. 🚀 Introducing GPT-5.5 A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done. Now available in ChatGPT and Codex. pic.twitter.com/rPLTk99ZH5 ...

Hello everyone! 😁 OpenAI announced a brand new model called GPT-5.3-Codex on February 5, 2026, and believe me, this model is truly a game-changer! 🚀 What is GPT-5.3-Codex? GPT-5.3-Codex is the most capable agentic coding model that OpenAI has developed to date. We previously wrote about the OpenAI Codex App , and now we have the most powerful model behind this platform! So what does “agentic” mean? The model doesn’t just write code for you; it can also take on long-running tasks like a colleague, conduct research, use tools, and execute complex operations. ...

Hello everyone! 🤩 We’ve been excitedly following developments in the world of AI and software for a long time. On February 2, 2026, news came from OpenAI that will shake up developers (in a good way, of course! 😉). Introducing: The OpenAI Codex App! The era of assistants that only complete code is ending; next up is the era of agentic coding. OpenAI announced the native Codex app for macOS to support this vision. Let’s take a closer look together at what this new app offers and how it might change our development habits. 👇🏻 ...
