No, it kept going in circles....spent like 3 weeks trying to fix it. Got access to gpt5 yesterday and all major bugs are resolved.
Interesting I tried it to fix some unit tests that were failing but made the problem worse. Sonnet was able to fix the failing unit tests and the new problems introduced by GPT5. I used Claude Code for Sonnet and Cursor Agent for GPT-5. Maybe Cursor Agent is just bad?
