Researchers have explored the impact of curriculum difficulty progression in GRPO (Group-Relative Policy Optimization) training. Their experiments on the GSM8K dataset indicate that while medium-difficulty samples are beneficial for initial training efficiency due to informative learning signals, a persistent focus on them does not yield the highest final model performance. A staged curriculum that progressively shifts to moderately harder samples improved test accuracy, but further progression to overly difficult samples led to a decrease in performance, suggesting a non-monotonic benefit to difficulty progression.
