OpenAI launches restricted GPT-6 Cyber model for finding and testing software flaws

says GPT-6 Cyber, available through the API and Codex to approved Daybreak Red customers, found 81 high-severity bugs and developed working exploits for 948 Linux kernel vulnerabilities, 588 of them previously unknown. Noma Security's Chris Hughes said the results suggest a deeper pool of flaws in mature software, while Dragos's Rob T. Lee warned that AI could also create new exploitation paths that make detection harder. OpenAI has not published metrics showing how much its models speed up enterprise patch deployment.
