I accidentally discovered Cursor's new Composer 2.5 model mid-project — and it was completing tasks 3–4x faster than Opus 4.7 with results that were just as good, if not better. I had no idea it had even switched. So I ran a proper head-to-head test: Composer 2.5 vs Opus 4.7 vs GPT 5.5 — all given the exact same prompt inside Cursor. The results surprised me.
