Foundation Models

Built for Scale. Engineered for Intelligence. Designed for Discovery.

Paige’s foundation models redefine what’s possible in pathology. Built on the world’s largest dataset of digitized slides, our technology captures the intricate complexities of tissue like never before—enabling new levels of discovery, precision, and performance.

Two Foundation Model Suites. Unlimited Possibilities.

Virchow: Vision AI

Virchow

The first million-slide foundation model for cancer, setting the benchmark for computational pathology

Virchow2

Expanded multi-scale training (H&E + IHC), boosting precision across 40+ tissue types

Virchow2G

Our largest model yet—1.8B parameters—optimized for high-stakes pathology AI

Virchow2G-Mini

A lightweight alternative, delivering high-throughput performance on limited compute

PRISM: Multi-Modal AI

  • Combines Large Vision Models (LVMs) with Large Language Models (LLMs) for slide-level analysis.

  • Built using Virchow, PRISM analyzes and extracts insights from tissue at the whole slide level

  • Automated Clinical Report Generation | Converts whole-slide images into free-text pathology reports

  • Zero-Shot Cancer Classification | Detects cancer subtypes and predicts biomarkers without extensive labeled data

  • Multi-Modal Intelligence | Trained from 587K slides and 195K clinical reports to generate text-based insights
