+> We observe that the **Qwen3.5** series models exhibit unusually strong performance on **RxnBench**, with metrics that are significantly higher than expected. Notably, the release date of Qwen3.5 is substantially later than the publication date of RxnBench. Therefore, we cannot rule out the possibility of potential data leakage.
