Summary

OpenAI is introducing GPT-6 Cyber, a restricted access model that the company calls its most capable and aligned cybersecurity model yet, “built to help security researchers identify and validate exploitable vulnerabilities, assess their impact, and harden potential patches before they’re released.” OpenAI researchers said they used GPT-6 Cyber to find 81 previously unknown high-severity vulnerabilities in Firefox and develop working exploits for 948 Linux kernel vulnerabilities, including 588 previously unknown vulnerabilities. Mozilla has begun releasing fixes, and Linux findings are being reported with candidate patches for maintainer review.
