Cursor released Composer 2.5 on May 18, its most capable in-house coding model, and built the launch around a single provocative claim: frontier-level agentic coding at roughly one-tenth the price of Claude Opus 4.7 or GPT-5.5. The headline is largely defensible. It is also selective, rests heavily on Cursor's own benchmarks, and carries caveats the marketing does not lead with.
