Published on October 14, Block’s account describes Daybreak and other OpenAI systems for vulnerability discovery, detection and response. In red-team exercises, the time from a high-level vulnerability report to an automatically proposed patch is reported as 18 minutes.
A proposed patch is not a validated, deployed fix. The publication explicitly retains human validation and places the figures in internal exercises. It does not establish that every real vulnerability is remediated in 18 minutes.
