Security for the (vetted) masses is the promise of Daybreak (Picture: OpenAI)
Billed as the answer to Anthropic’s Mythos model, the new branding is basically just a suite of the models released last week — such as ChatGPT-5.5-Cyber — and the new Codex Security.

— Daybreak combines the intelligence of OpenAI models, the extensibility of Codex as an agentic harness, and our partners across the security flywheel to help make the world safer for everyone, OpenAI writes.

The more advanced models require a screening of users, and the better they get, the more serious the vetting.

— Because those same capabilities can be misused, Daybreak pairs expanded defensive capability with trust, verification, proportional safeguards, and accountability.

Also new is that OpenAI now offers a vulnerability scan as a way into the ecosystem, available for businesses of all sizes and systems.
