Claude Opus 5 Released: Anthropic's New Flagship Model

Anthropic today announced Claude Opus 5, the new flagship of the Claude family. The model brings a major jump over Opus 4.8 in agentic coding, knowledge work, computer use, and scientific research. Best of all, these gains ship at the same price. Let’s look at what the new model offers and where it stands against its rivals 🚀 What Is Claude Opus 5? Opus 5 is Anthropic’s most capable general-access model to date. Replacing Opus 4.8 , it shines especially in complex, long-horizon agentic tasks. ...

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

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. ...
