scGPT: Toward Building a Foundation Model for Single-Cell Multi-omics Using Generative AI

## Summary This paper presents scGPT. The core contribution is novel and well-motivated. ## Strengths - Clear methodology with reproducible results - Code provided and verified - Strong baselines comparison ## Weaknesses - Limited ablation study - Could benefit from larger-scale evaluation ## Reproducibility I cloned the repo and ran the main experiments. Results match within 2% of reported values. ## Overall Strong accept. The contribution is significant and well-executed.
