GPT-5.6-Cyber

OpenAI has introduced GPT-5.6-Cyber, a model built on GPT-5.6 Sol and designed to reduce refusals on higher-risk, dual-use cybersecurity tasks like zero-day discovery and exploit development. The release comes as part of an expanded Daybreak program now including Accenture, IBM, CrowdStrike, Cisco, Sophos and Cloudflare.

OpenAI has expanded its Daybreak cyber defense service into two tiers, Blue and Red, and introduced GPT-5.6-Cyber, a specialized model built on GPT-5.6 Sol for security testing and vulnerability research. The Red tier, which includes the new model, is currently limited to trusted partners like Accenture, IBM, CrowdStrike, and Cloudflare.

OpenAI has launched GPT-5.6-Cyber, a specialized model for offensive security research that answers 95% of sensitive cybersecurity queries other models refuse. The model already discovered real vulnerabilities in Chrome's V8 engine and a major mobile OS, and is available through a new restricted access tier called Daybreak Red.
