kept by eddie mar 27

Cursor uses real-time reinforcement learning on live user interactions to ship improved Composer model checkpoints every five hours.

Training Composer for longer horizons
Cursor trains Composer to generate its own compact summaries mid-task, reducing context errors by 50% while using 80% fewer tokens than traditional prompting.
