arXiv:2601.09085v2 Announce Type: replace Abstract: Group Relative Policy Optimization (GRPO) has become a standard approach for training mathematical reasoning models; however, its reliance on multiple completions per prompt makes training computationally expensive. Although recent work has reduced the number of training steps required to reach peak performance, the overall wall-clock training time often remains unchanged or even increases due to higher per-step cost. We propose MMR-GRPO, which integrates Maximal Marginal Relevance to reweigh rewards based on completion diversity. Our key ins
The continuous drive for more efficient AI training methods, particularly for computationally intensive models, makes innovations like MMR-GRPO timely.
Accelerating the training of mathematical reasoning models directly impacts the development speed and practical deployability of advanced AI systems, reducing current computational bottlenecks.
Training times for certain complex AI models may be significantly reduced, making them more accessible and cost-effective to develop and iterate upon.
