Regarding the $200 subscription. For Claude Code with Opus (and also Sonnet) you need that, yes.

I had ChatGPT Codex GPT5.2 high reasoning running on my side project for multiple hours the last nights. It created a server deployment for QA and PROD + client builds. It waited for the builds to complete, got the logs from Github Actions and fixed problems. Only after 4 days of this (around 2-4 hours) active coding I reached the weekly limit for the ChatGPT Plus Plan (23€). Far better value so far.

To be fully honest, it fucked up one flyway script. I have to fix this now my self :D. Will write a note in the Agent.md to never alter existing scripts. But the work otherwise was quite solid and now my server is properly deployed. If I would switch between High reasoning for Planing and Middle reasoning for coding, I would get even more usage.

> ChatGPT Codex GPT5.2 high reasoning

"... brought to you by Costco."

But seriously, I can't help but think that this proliferation of massive numbers of iterations on these models and productizations of the models is an indication that their owners have no idea what they are doing with any of it. They're making variations and throwing them against the wall to see what sticks.

		It's really not that hard. Codex = The model trained specifically for programming tasks. You want this if you're writing code. GPT5.2 = The current version. You don't have to think about this, you just use the latest. High Reasoning = A setting you select for balancing between longer thinking time or quicker answers. It's usually set and forget.
