OpenAI engineers have made Ultrafast, a high-speed mode in Codex, their default for incident response, cutting security investigations from an hour or two to 10 to 15 minutes.
- The company published the internal accounts as part of a series on how its own teams use its technology and APIs.
- Aaron Friel, a member of the technical staff, says Codex lets him search many possible causes at once instead of one haystack at a time.
- AJ Trbojevic, a datacenter security architect, says pulling structured and unstructured data together and normalizing it now takes 10 to 15 minutes and is at times near real time.
- Jeff Niu says most of his work now returns an answer in under 30 seconds, the threshold past which he says he would check Slack or ask a coworker instead.
- Engineers also describe using Codex for large refactors, morning planning summaries and browser form-filling, with Adam Perry saying he can now stay focused rather than split his attention.
