This post on what it’s like to work at OpenAI is fascinating. A wealth of great insight into the craziness of one of the world’s fastest-growing companies. One thing that stood out to me was this about CODEX:

From start (the first lines of code written) to finish, the whole product was built in just 7 weeks.

Now, to be fair, they’d been thinking about it since November 2024, but still just “7 weeks”! I’ve been using CODEX for the last few weeks instead of Cursor or Claude Code to tinker around, and it’s really fun to just have it go off and do work.
