OpenAI GPT-6 Cyber: a hacking model for vetted defenders only
OpenAI's GPT-6 Cyber finds software flaws, builds working exploits, and writes fixes — available only to approved Daybreak Red defenders.
Why it matters
Rated Critical for cybersecurity, it found 81 previously unknown high-severity Firefox flaws and drove an autonomous pipeline that produced 948 working Linux kernel privilege-escalation exploits with candidate patches.
What you could build with it
A security team could use the model as a pre-release audit layer, running it against a staging codebase to surface exploitable flaws and draft patches before a human review signs off.
Does it hold up?
Too early to judge — access is limited to vetted Daybreak Red customers, so no independent hands-on evidence exists yet; the 948-exploit kernel run is OpenAI's own demonstration.
