OpenAI’s Codex has gone from coding assistant to something closer to an organizational operating system. The company now says the AI agent generates 99.8% of all output tokens produced internally on a weekly basis.
Engineering teams alone produce 99% of their output tokens through Codex, surpassing even ChatGPT. But the real story isn’t about engineers. It’s about everyone else.
Non-developers are the fastest-growing user base
Since August 2025, non-developer organizational users of Codex have grown 189x. Individual non-developer users have grown 137x over the same period. Within OpenAI itself, non-developer adoption is up 12x.
Non-developers now make up roughly 20% of Codex’s total user base. They’re growing at more than three times the rate of developers.
