OpenAI Launches Two-Tier Daybreak Program With Specialized Cyber AI That Completes 95% of Advanced Security Requests

OpenAI launches a two-tier Daybreak cybersecurity program featuring GPT-5.6-Cyber, a specialized AI model completing 95% of advanced security requests — compared to just 1.5% for standard models — already uncovering real Chrome vulnerabilities, with strict identity verification and hardware security key requirements to prevent misuse.

• OpenAI is expanding its Daybreak program with two access tiers — Daybreak Blue for general defensive security work and Daybreak Red for advanced vulnerability research — giving approved defenders access to frontier AI capabilities before attackers can deploy offensive AI at scale.
• A new cybersecurity-specific model, GPT-5.6-Cyber, is now available through Daybreak Red, completing 95% of advanced cybersecurity requests compared to just 1.5% for the standard GPT-5.6 Sol, and has already been used to discover real-world vulnerabilities including two previously unknown V8 flaws in Chrome, assigned as CVE-2026-15903.
• Access to both Daybreak tiers requires identity verification, legal attestations, and account security measures, with additional safeguards including mandatory hardware security keys starting September 1, 2026, auto-review mode for elevated-permission actions, and sandbox isolation requirements to prevent misuse.
