This dataset is designed as a sanity test on RL algorithms for [`DeepSeek-R1-Distill-Qwen-1.5B`](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Qwen-1.5B) model under 8k context length.

A reliable RL algorithm should achieve above 95% training accuracy for BF16 and 98% for FP16.

This is the dataset used in the paper: Defeating the Training-Inference Mismatch via FP16.

We construct this dataset by filtering out those overly trivial and unsolvable questions for the initial model. Specifically, we unroll 40 responses for each problem in the MATH dataset, and only keep problems where the initial accuracy is between 20\% and 80\%. This process yielded a targeted dataset of 1,460 questions for the DeepSeek-R1-Distill-Qwen-1.5B model. The smaller size of this dataset makes achieving near-100\% accuracy computationally feasible, allowing for efficient and conclusive testing.
