GPT 5.2 xhigh feels like a much more careful architecter and debugger, when it comes to complex systems

But most people here think Opus 4.5 is the best model in that category

There are 2 reasons AFAIS:
- xhigh reasoning consumes significantly more tokens. You need to pay for ChatGPT Pro (200 usd) to be able to use it as a daily driver
- It takes like 5x longer to finish a task, and most people lack the patience to wait for it. (But then it's more correct/doesn't need fixing)

Opus 4.5 is good too, I think better in e.g. frontend design. But if you think it beats GPT 5.2 in every category, you are either too poor/stingy or have ADHD
