OpenAI Releases GPT-6 Cyber for Security Research

Key Info

OpenAI has released GPT-6 Cyber, described as a major advance in security research that pairs stronger capabilities with better model alignment. The model powered recently announced Linux kernel research and is being used by security teams at companies including Mozilla, Palo Alto Networks, Calif, and Cisco, as well as inside OpenAI.

Highlights

• GPT-6 Cyber is positioned as a step forward for defenders, with stronger vulnerability research and improved alignment.
• It powered the Linux kernel research OpenAI announced the day before.
• Security teams at Mozilla, Palo Alto Networks, Calif, and Cisco are using it alongside OpenAI's own teams.
• OpenAI staff report using GPT-6 Cyber together with GPT-6 Astra and Daybreak to find weaknesses, validate impact, and develop fixes.
• A pre-release GPT-6 Astra test involved examining low-risk research infrastructure tools, such as a math task grader built on the SymPy library.
