Training Composer for longer horizons

kept by eddie mar 18

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

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

First make it fast, then make it smart
Faster AI coding models, even if less intelligent, are more productive for quick mechanical code edits than slower, smarter models, especially for users with short attention spans.

Agents are not thinking, they are searching
AI agents are not thinking but searching through trajectories toward reward signals; environment and context window bound the search space.

The value of AI agents lies in the RL-trained model, not in code abstractions; an agent is just a loop that calls the model until it stops.
