Medical AI trained on whopping 57 million health records (Nature)

In a groundbreaking move, researchers in the UK have trained a generative AI model called Foresight on anonymized health records from 57 million patients within England’s NHS — the largest dataset of its kind ever used. Built to predict hospitalizations and various health conditions, the model is currently restricted to COVID-19-related research within a secure NHS environment. While early versions of Foresight showed high accuracy, the latest iteration draws on 10 billion clinical events from 2018 to 2022. Experts say this could significantly advance predictive health AI, though privacy concerns remain.
