Just started with ChatGPT5.3 Codex. I have been very happy with ChatGPT5.2, using it in a very controlled, isolated way, but this is next level s***. I was planning to this hardening stuff, later on, but holy crap, I did in 15 minutes what I figured would have taken me a month to do.

I use that opus model a lot, hard to use it all the time as it’s expensive. Codex 5.3 is a great tool for the cost.

Not on ppq or routstr yet :-(
