OpenAI is launching
Daybreak
, an AI initiative focused on detecting and patching vulnerabilities before attackers find them. Daybreak uses the Codex Security AI agent that
launched in March
to create a threat model based on an organization’s code and focus on possible attack paths, validate likely vulnerabilities, and then automate the detection of the higher risk ones.
Its launch comes just over a month after rival Anthropic announced
Claude Mythos
, a security-focused AI model it claimed was too dangerous to publicly release and only shared privately as a part of its own initiative, dubbed Project Glasswing. Still, that didn’t stop at least a few unauthorized parties
from getting access
.
However, OpenAI has so far lacked a similar security product. Like Glasswing, Daybreak isn’t built on just one AI model — OpenAI
“Daybreak brings together the most capable OpenAI models, Codex, and our security partners.”
Daybreak also involves specialized cyber models, including
GPT-5.5 with Trusted Access for Cyber and GPT-5.5-Cyber
, which began rolling out last week. OpenAI also says it’s working with its “industry and government partners” while it prepares to “deploy increasingly more cyber-capable models.”
