Light-R1-32B-DS is a near-SOTA 32B math model with AIME24 & 25 scores 78.1 & 65.9.
Originated from DeepSeek-R1-Distill-Qwen-32B, Light-R1-32B-DS is further trained with only [3K SFT data](https://huggingface.co/datasets/qihoo360/Light-R1-SFTData) as we've open-sourced, demonstrating the strong applicability of the released data.
We are excited to release this model along with the [technical report](https://arxiv.org/abs/2503.10460).
## Usage
Same as DeepSeek-R1-Distill-Qwen-32B.
## Data Decontamination
We carefully evaluated data contamination of several open-sourced datasets.
While certain contamination may be [inevitable during pre-training](https://x.com/DimitrisPapail/status/1888325914603516214),
it is unacceptable for post-training to compare on benchmarks.
MATH-500 is somewhat compromised with tens of questions that are identical or only numbers changed. AIME 24 and 25 stay intact but we have to pay special attention when we incorporate AIME data up to 2023.
Light-R1 did thorough decontamination with exact matching (excluding digits) and N-gram (N=32) matching.
