I’ve been using OpenAI’s codex has my agentic harness application for personal use and at work too. And, I must say I’ve been tired of downloading new updates every single day on multiple devices.

It’s like they ship something twice or thrice a day (at-least on the macOS desktop app). And, I’ve been wondering ever since.

How do they ship at this cadence? I get it that they have a large engineering team but still…

Surely, they’re doing something right.

That led me to question “What does their SDLC look like?”

I asked this question into Codex itself!

The answer is not in this PDF but it’s breadcrumb trail to the answer:
