Virchow / Virchow2 (Paige, MSK)
A pathology foundation model trained on millions of slides that can detect cancer and predict biomarkers from an ordinary H&E slide.
Virchow (2024, 632M parameters, 1.5M slides) and Virchow2/2G (2024, up to 1.9B parameters, 3.1M slides from MSK and global sites, mixed magnification) are the largest proprietary pathology foundation models; they underpin Paige's pan-cancer detection and biomarker products and were trained with Microsoft compute.
How it works
Self-supervised DINOv2 vision transformer pretraining on tissue tiles at several magnifications; frozen encoder plus small task heads.
- Scale and data diversity
- Strong biomarker prediction from H&E
- Proprietary weights
- Scanner and stain shift
