✓Dual-Tier Defensive Framework: Daybreak Blue provides access to GPT-5.6 Sol with reduced guardrails for general defense, while Daybreak Red provides vetted researchers access to GPT-5.6-Cyber for dual-use vulnerability research.
✓95.0% Advanced Completion Rate: GPT-5.6-Cyber completes 95.0% of advanced cybersecurity requests (auth bypass, privilege escalation, exploit chains), compared to just 1.5% for standard GPT-5.6 Sol and 57.3% for GPT-5.5-Cyber.
✓CVE-2026-15903 Discovered: GPT-5.6-Cyber identified two chained zero-day vulnerabilities in Chrome’s V8 JavaScript engine (JIT compiler bounds check skip and JSPI stack escape), assigned CVE-2026-15903 and patched by Google.
