Cursor's Composer 2 model praised, built on an open-source base

Aman Sanger of Cursor says Composer 2 is a really good model and he is excited for more people to try it. The quoted reply from Lee Robinson says Composer 2 started from an open-source base, with only about one-quarter of the final model's compute coming from that base. Cursor plans full pretraining in the future and says it is following the license through its inference partner terms.
