OpenAI says its new GPT-6 Cyber has already uncovered 'thousands' of exploits

OpenAI has launched GPT-6, a cybersecurity AI model that delivers "major gains" on key cybersecurity benchmarks over its predecessor, GPT-5.6 Cyber. In an introductory blog post published on Thursday, OpenAI said that GPT-6 Cyber delivers a 51% improvement over GPT-5.6 Cyber on the ExploitGym cybersecurity benchmark. GPT-6 Cyber is "already helping to secure real-world software, uncovering and validating thousands of exploits in security-critical codebases such as Linux and Firefox," said the post. The news comes days after it was revealed that OpenAI's upcoming model (now confirmed to be GPT-6 Cyber by OpenAI) had found and patched 948 local privilege-escalation vulnerabilities in Linux.
