Cursor's Composer 2.5 Fast Wins on Both Speed and Quality

Composer 2.5 Fast breaks the conventional speed-quality tradeoff by delivering both higher benchmark scores and 32% faster execution than the standard version—all within Cursor's fixed subscription at no additional cost. This creates a decisive advantage over pay-per-token models like GPT-5.5, reshaping the cost-performance calculation for developers. The result challenges the industry's implicit assumption that optimization requires sacrificing quality.
