Cursor: Training Composer
Registration
About Event
Join Sasha Rush, ML researcher at Cursor, for a walkthrough of the training behind Composer 2, Cursor's model for agentic software engineering.
We cover:
The two-phase training process: continued pretraining, followed by large-scale reinforcement learning
How CursorBench, built from real engineering sessions, evaluates real-world coding tasks
The infrastructure behind training: custom MoE kernels, a fully async RL pipeline, and sandboxed coding environments at scale
This session will be recorded and shared with everyone registered.
