official (OpenAI introducing GPT-6 Cyber, Nov 5; Linux pipeline companion post Nov 4 already on site); Daybreak Red only; Preparedness Framework rating Critical for cybersecurity

OpenAI names GPT-6 Cyber: Critical cyber rating, 81 novel Firefox highs, Daybreak Red gate — Linux 948-LPE pipeline was this model

  • What changed vs the Nov 4 note: the unnamed 'upcoming cyber model' is now GPT-6 Cyber; Firefox campaign numbers and the Critical rating are new; Daybreak Red / Blue split and critical-infrastructure defender track are spelled out.
  • Alignment claim to weigh: ExploitGym Honeypot (inspired by the Hugging Face incident) — 99.93% avoided out-of-scope services without the deployment prompt, 100% with it (vs 94.49% for GPT-5.6 Cyber).
  • Ops implication: expect faster patch volume from vendors using these agents; treat unauthenticated 'AI found N kernel bugs' social posts as marketing until a CVE or maintainer ack lands.
