Model Card for DAPO w/ Prompt Augmentation

If you are using the model, a star to our github repo would be really appreciated! 😊

This is the step 2720 checkpoint when training Qwen2.5-Math-1.5B on MATH Level-3-to-5 Dataset using DAPO (no dynamic sampling) with prompt augmentation. The training procedure is outlined in the paper Prompt Augmentation Scales up GRPO Training on Mathematical Reasoning.
