| X-Cell | associated with | Perturbation response prediction | medium | VC0033 · preprint supports Preprint. From: AI virtual cell models |
| X-Cell | benchmarked on | Simple linear baseline | low | VC0033 · preprint supports VC0048 contradicts X-Cell (preprint, not peer reviewed) claims to surpass linear baselines, whereas the Nature Methods benchmark found earlier deep models did not; VC0048 does not test X-Cell, so the “contradicts” role is a tension, not a refutation. Needs review. |
