Exact same experience here. Prior to Opus 4.5 I'd sometimes use AI for some frontend webdev stuff (I am a C/C++/Python programmer; my HTML/CSS/JS knowledge is probably on par with a first-year uni student) and I'd have to manually edit things and retry, tell it not to attempt a paradigm that had failed before or cycle between models in Cursor just to try and get one that could make a simple widget that worked properly.

Now, I'm using Claude or Codex (GPT-5.5) for frontend and backend and it just gets it right first time more often than not. I've been making use of things like LSPs, Context7 and CLAUDE.md (global and per-repo) and it just stops doing the dumb LLM things that I hate.
