Researchers have developed DataFlex-RL, a new platform designed to evaluate data policies for reinforcement learning with verifiable rewards (RLVR). Initial experiments using Qwen2.5-7B-Base across 12 benchmarks showed that while uniform GRPO improved accuracy, none of the tested rollout-selection or reweighting methods consistently outperformed uniform sampling. Further tests with Llama-3.1-8B-Base did not identify a clear winner among the methods. The study also found that evaluation rankings can vary significantly based on the chosen benchmark set, suggesting that current data policies do not consistently yield reproducible improvements over uniform training.

IMPACT This research suggests that current methods for optimizing data selection in RLVR may not offer significant, reproducible improvements, potentially guiding future research towards more effective data policy strategies.
