OpenAI Splits Daybreak Into Two Tiers, Releases GPT-5.6-Cyber for Security Research
OpenAI has expanded its Daybreak cybersecurity program into two access tiers – Daybreak Blue for general defenders and Daybreak Red for advanced research – and released a new model, GPT-5.6-Cyber, designed to reduce refusals on exploit development and vulnerability research. The model uncovered real vulnerabilities in Chrome's V8 engine and other software, while OpenAI tightens governance with hardware key requirements and Codex auto-review mode.
