Small-Scale Question Sunday for February 1, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

We build Claude with Claude. Our engineers write code with Claude Code every day, and every new model first gets tested on our own work.

and (https://openai.com/index/introducing-gpt-5-3-codex/)

GPT‑5.3‑Codex is our first model that was instrumental in creating itself. The Codex team used early versions to debug its own training, manage its own deployment, and diagnose test results and evaluations—our team was blown away by how much Codex was able to accelerate its own development.

I believe these claims. The models are not and could not autonomously develop themselves, human developers are using them for assistance. I'm sure humans are still doing the high-level reasoning, as both quotes focus on simpler tasks ("straightforward parts" for Opus, and debugging/testing for Codex).
