OpenAI has unveiled GPT-6 Cyber, a new artificial intelligence model specifically designed for cybersecurity research and vulnerability discovery. The model has identified 81 previously unknown high-severity vulnerabilities in Firefox and developed working exploits for 948 distinct Linux kernel flaws. This represents a significant milestone in AI-assisted vulnerability research, demonstrating the potential of large language models to autonomously discover and exploit security weaknesses at scale. The discovery raises important questions about the dual-use nature of AI in cybersecurity, as the same capabilities that enable proactive defense could also be leveraged offensively. The scale of vulnerabilities found across two major open-source projects highlights the profound impact AI-driven security research may have on the industry.
