Cursor releases Composer 2.5 coding model

Cursor 发布 Composer 2.5 编程模型

Cursor released Composer 2.5, claiming up to 10x higher efficiency on long coding tasks; the model is further trained on Moonshot’s Kimi K2.5 and uses text feedback for 100k-token-scale trajectories.

Why it matters: HKR-H/K/R all pass: Cursor is a core AI coding tool, and Composer 2.5 adds concrete claims around 10x long-task gains and Kimi K2.5 tuning. Limited sourcing and no independent eval keep it in the 78–84 band.
