OpenAI releases GPT-6 Cyber, and promises this one stays within 'rules of engagement'

OpenAI has introduced GPT-6 Cyber, a restricted model designed to help security researchers identify exploitable vulnerabilities and harden patches. The model discovered 81 unknown high-severity vulnerabilities in Firefox and developed exploits for 948 Linux kernel vulnerabilities, including 588 previously unknown ones. Mozilla is releasing fixes, and Linux findings are under maintainer review. OpenAI claims the model adhered to rules of engagement, avoiding out-of-scope services over 99 percent of the time during its research operations.
