Cursor Introduces Composer 2.5

Cursor has released Composer 2.5, an enhanced AI coding assistant for its code editor built on Moonshot's Kimi K2.5 checkpoint, featuring improved task persistence, complex instruction following, and usability via advanced training methods like targeted textual feedback, 25x more synthetic coding tasks, and an optimized training stack. The model is priced at $0.50 per million input tokens and $2.50 per million output tokens (with a faster variant at higher rates), offers double usage for the first week, and Cursor is collaborating with SpaceXAI to develop a significantly larger model from scratch using 10x more compute and Colossus 2's infrastructure.
