OpenAI launches GPT-5.6-Cyber as AI narrows vulnerability response window
Brief
OpenAI has expanded its Daybreak cybersecurity program and introduced GPT-5.6-Cyber, a specialized model for approved security researchers, as the company warned that AI could give defenders less time to respond to developing threats.
Daybreak now has two access levels. Blue gives approved defenders access to frontier general-purpose models such as GPT-5. 6 Sol for authorized defensive work, while Red provides specialized cyber models for more advanced activities, including vulnerability research, exploit validation, and security testing.
OpenAI said GPT-5. 6-Cyber is designed to reduce refusals on higher-risk security tasks while improving its ability to conduct exploit development and vulnerability research. In an internal evaluation measuring how often models responded to advanced cybersecurity requests rather than refusing them, GPT-5.
