Expanding Daybreak as the Cyber Defense Window Narrows

OpenAI has launched Daybreak, a cybersecurity initiative utilizing frontier AI to manage the complete defensive cycle. The program integrates Codex Security and GPT-5.6-Cyber, a specialized model available via Daybreak Red for authorized vulnerability research, exploit validation, and security testing. Rather than focusing solely on alert generation, Daybreak enables teams to find, validate, and fix vulnerabilities before attackers can exploit them. This approach ensures practical remediation and verification, strengthening the overall cyber defense window for enterprises and developers.
