OPENAI DROPPED A PDF ON HOW THEY USE CODEX INTERNALLY

and it's actually useful

their engineers across security, infra, frontend, and api teams use it daily for:

▫️ understanding unfamiliar codebases fast (especially during incidents)

▫️ refactoring changes that span dozens of files

▫️ generating tests for edge cases devs usually miss

▫️ scaffolding boilerplate so you ship faster

▫️ staying in flow when your calendar is a disaster

the one that hit different:

one engineer said "i was in meetings all day and still merged 4 PRs because codex was working in the background"
