100-word summary
Ramp engineers who used to wait hours for their first code review now get substantive feedback in minutes using OpenAI's Codex with GPT-5.5. The tool became so trusted it's now mandatory in many review workflows, with developers requesting it by name and calling it the "industry gold standard." The surprise? Engineers say the AI catches things human reviewers often miss because it has time for thoroughness that humans don't. Ramp is also building its On-Call Assistant with Codex, shipping incident-response improvements faster than before. The case study skips exact time savings, but the shift from hours to minutes suggests code velocity just got a meaningful boost.
