The cybersecurity world is rapidly changing—threat actors will increasingly use AI to conduct cyberattacks at unprecedented speed and scale, including in fully autonomous ways. As these capabilities spread, defenders have a narrowing window to prepare. Our answer is to put frontier intelligence in the hands of trusted defenders everywhere before attackers deploy offensive AI capabilities at scale.

We’re expanding OpenAI Daybreak with two access tiers designed to give approved defenders the right capabilities for their work: Daybreak Blue provides access to frontier general-purpose models, including GPT‑5.6 Sol, with safeguards tailored to authorized defensive security work. Daybreak Red provides access to our purpose-trained cybersecurity models for authorized vulnerability research, exploit validation, and security testing. We’re also introducing GPT‑5.6‑Cyber, available through Daybreak Red.

GPT‑5.6‑Cyber completes 95.0% of advanced cybersecurity requests in our internal evaluation, compared with just 1.5% for GPT‑5.6 Sol, and 2.0% when used with Daybreak Blue access. It also completes more requests than GPT‑5.5‑Cyber, which completes only 57.3% of requests, addressing feedback from security researchers who encountered persistent refusals with the earlier model.
