Introducing GPT?6 Cyber: a major advance in security research that pairs stronger capabilities with better model alignment. The model powered the Linux kernel research we announced yesterday, and security teams at companies like Mozilla, Palo Alto Networks, Calif, and Ciscoā€”alongside our own at OpenAIā€”are already putting it to work. GPT-6 Cyber is available to select Daybreak Red customers and we are expanding access over time. -- openai 05-NOV-2026 12:09 PM ET
