Have had fairly good luck with Claude Code Opus 4.7 on xhigh effort.

I think it more reliably does IaC with established patterns especially when it can do a dry run.

Python is pretty decent but usually you need good prompting and a little bit of steering to prevent slop. The slop usually works tho

Codex w/ gpt-5.5 seems faster but maybe just a bit below Opus 4.7 quality.

I gave Opus access to a repl (pyrasite-ng) in a running Python process and it managed to find an 8 year old "memory leak"--a module level cache with no eviction. It did that using GC module and exploring the heap. I was pretty happy with that outcome. It would have been quite challenging for me to find myself without at least a few weeks of deep diving into memory leak hunting docs/resources.
