– Built on Epic Cosmos, a secure data platform, Comet is designed to predict what is likely to happen next in a patient’s journey by estimating disease risk, length of stay, and treatment outcomes. The platform has learned from more than 100 billion patient medical events to calculate these likely futures. Using the same core technology as today’s large language models, Comet learns how clinical patterns evolve over time. Designed for Security and Shared LearningComet is built entirely within Epic Cosmos, a secure, collaborative data platform for large-scale health research and innovation. Operating within this governed environment, Comet can surface insights to participating health systems without compromising patient privacy.
