Variance Reduction and GRPO Advantages

What does it really take to train an AI to write great code? In this roundtable conversation, some of the founders and researchers at Cursor explore the process of building superhuman AI coding agents — from infinite context models and the best rewards to real-time RL and scaling to millions of environments.This is an inside look at some of the work behind Cursor and what AI-assisted coding might look like in the future.
