Composer is a new model we built at Cursor. We used RL to train a big MoE model to be really good at real-world coding, and also very fast. cursor.com/blog/composer Excited for the potential of building specialized models to help in critical domains.

Was this what was once Cheetah? If so Composer is not available in cmd+k inline edits and that was my favorite place to use Cheetah.

Cheetah was the v0 of this model primarily to test speed. > In our development process, we experimented with a prototype agent model, codenamed Cheetah, to better understand the impact of faster agent models. Ah I will tell the product team.
