There’s been a lot of noise about Claude performance degradation, and the current best option is probably Codex, but this still surprises me. It sounds like it succeeded on the hard part, then stumbled on the easy bit.

Just two questions, if you don’t mind satisfying my curiosity.

- Did you tell it to write C? Or better yet, what was the prompt? You can use Claude --resume to easily find that.

- Which model? (Sooner or Opus)? Though I’d have expected either one to work.
