OpenAI says its Astra-powered Daybreak cybersecurity initiative can help security teams examine legacy code, analyze suspicious activity, identify vulnerabilities, prioritize risks, and develop fixes as AI accelerates cyber threats.

AI-driven cyberattacks are expected to grow with advances in AI models, prompting defenders to rapidly identify and remediate vulnerabilities.

Experts warn that autonomous, scalable AI attacks could target critical infrastructure, a concern OpenAI highlights to motivate Daybreak.

Initial Daybreak focus targets critical infrastructure sectors such as water, electricity, local government services, and financial institutions, with subsidized access planned for six months and then expansion to partner countries.

Astra is initially limited to select organizations, with plans to broaden to ChatGPT Plus/Pro/Business/Enterprise users, OpenAI API, and AWS, priced at $10 per million input tokens and $50 per million output tokens.

Benchmarking shows GPT-6 Astra outperforming Claude Fable 5.1 and Google Gemini 3.8 Flash across multiple tests, including ARC-AGI-3 and FrontierMath Tier 4.

Astra reportedly scores 98% on FrontierMath Tier 4, 99.9% on ARC-AGI-3, and 64.6% on Terminal-Bench Science 0.1, with action-efficiency exceeding human baselines on most ARC-AGI-3 levels.

Regulation in the U.S. remains unsettled, with no federal law governing these models, though a voluntary federal review exists; OpenAI says partners and access will not require separate government approval this time.

MS-ISAC provides threat intelligence, incident-response support, and real-time information sharing to thousands of public-sector organizations.

OpenAI will extend support and resources to open-source maintainers as part of the program.

OpenAI notes competition with Anthropic, which launched Claude Mythos Preview and Project Glasswing in 2026, initially to around 50 organizations and later expanding to roughly 150 new organizations in over 15 countries.
