sGPO: Trading Inference FLOPs for Training Efficiency in RLVR
Researchers introduce sGPO (sorted Group Policy Optimization), a training method that reduces computational waste in reinforcement learning by using cheap inference to profile query difficulty and dynamically allocate training resources. The approach achieves 3x reduction in total training compute while maintaining or improving performance, representing a significant efficiency breakthrough for large-scale AI model training.
