Latest Cursor Composer undercuts software coding model competition

Good news!  Amazing stuff! Automated coding gets faster, better and cheaper by the hour!

"Cursor’s coding model rivals leaders at lower price

Cursor shipped Composer 2.5, a coding model built on Moonshot’s open-source Kimi K2.5 and trained on 25 times more synthetic tasks than its predecessor. It scores 79.8 percent on SWE-Bench Multilingual,  beating GPT-5.5 (77.8 percent) and coming within one point of Claude Opus 4.7 (80.5 percent), and 63.2 percent on CursorBench v3.1, broadly in line with both frontier models. It's not clear whether Cursor has achieved true parity: Comparisons mix Cursor’s own harness with self-reported competitor numbers and have not yet been independently reproduced on a unified scaffold.

But Composer operates at a fraction of the cost: $0.50/$2.50 per million input/output tokens versus Anthropic and OpenAI’s substantially higher rates. A faster variant delivers the same performance at $3.00/$15.00 per million tokens.  ..."
