Microsoft has partnered with digital pathology provider Paige to create the world's largest AI model for cancer detection. This model, trained on a massive dataset of billions of images, aims to identify common and rare cancers, potentially aiding doctors facing staff shortages. Paige specializes in digitizing pathology workflows, making diagnoses more accurate and efficient. They've received FDA approval for their AI tools, but storage costs have limited adoption. Paige collaborated with Microsoft to build a massive AI model trained on 4 million slides, significantly larger than any previous model. The goal is to enrich, not replace, pathologists, and their research could revolutionize cancer care, especially in underserved areas. The partnership plans to publish their findings and undergo extensive testing and regulatory approvals before making the AI model widely available.
