Composer-2 is based on Kimi K2.5, but with extensive RL. Cursor estimated 3x more compute on their RL than the original K2.5 training run (some details in https://cursor.com/blog/composer-2-technical-report).
Composer-2 seems very useful in Cursor, while K2.6 according to AA seems to be a really useful general model: https://artificialanalysis.ai/articles/kimi-k2-6-the-new-lea...
I used to hate on Composer 2 but I'm coming around to it. Opus for the big stuff and multi-file operations, Composer for all the small day-to-day IDE tasks works pretty good for me.
