I found that after obtaining the OpenAI cybersecurity certification, Codex adds a Daybreak Blue option. In simple terms, it's a version of GPT-5.6 Sol with fewer system-level restrictions, designed for verified security researchers. It's great for tasks like vulnerability discovery, code auditing, malware analysis, and patch validation—basically, a blue team tool. On the other hand, OpenAI also offers a Daybreak Red option, which is based on the more powerful GPT-5.6-Cyber model. This model is specifically trained for cyber-focused tasks on top of GPT-5.6 Sol, leaning towards exploits, 0-days, authentication bypass, privilege escalation, and penetration testing—essentially a red team tool. https://(openai.com)/index/expanding-daybreak-as-the-cyber-defense-window-narrows/
