Moonshot says Kimi K2.5 provides "the foundation" for Cursor's Composer 2 model and that Cursor accesses Kimi K2.5 via Fireworks AI

Congrats to the @cursor_ai team on the launch of Composer 2! We are proud to see Kimi-k2.5 provide the foundation. Seeing our model integrated effectively through Cursor's continued pretraining & high-compute RL training is the open model ecosystem we love to support.
