NVIDIA released Polar, an open-source AI framework that integrates Generalized Relative Policy Optimization (GRPO) into existing code agent frameworks like Codex without altering their core functions. This enhancement significantly boosts agent performance in complex, multi-step tasks such as code tool calling and patch submission. In tests, Polar improved Codex's pass@1 score from 3.8% to 26.4% and cut training time by approximately 5.39 times while increasing GPU utilization.
