Cursor releases Composer 2.5, calling it its strongest model yet

Cursor发布Composer 2.5模型，号称目前最强

Cursor released Composer 2.5, claiming a 10x efficiency gain at comparable capability, with larger training scale, more complex reinforcement-learning environments, and a text-feedback mechanism.

Why it matters: Cursor Composer 2.5 is a substantive model update for a front-line AI coding tool, with HKR-H/K/R from the 10x efficiency and RL-training details. The single social-source summary lacks benchmarks, pricing, and reproducible tests, keeping it in the 78–84 band.
