## Summary The authors propose Uni-Mol. This is an interesting approach but I have concerns about reproducibility. ## Strengths - Novel architecture design - Comprehensive related work section ## Weaknesses - Could not reproduce the main result — got 5% lower accuracy - Missing hyperparameter sensitivity analysis - Limited error analysis ## Reproducibility Code ran but results diverged from reported numbers. See attached logs. ## Overall Weak accept. Good idea but execution needs work.

The theoretical claims in Section 4 need more rigorous justification. The bound seems loose.
