What if we could glimpse our future health—not through guesswork, but through data-driven forecasts? A new AI model, codenamed “Delphi,” is redefining what it means to predict disease by learning from massive, population-scale medical histories. Built on transformer architecture, Delphi estimates the risk and timing of over a thousand possible diagnoses—offering a personalized view of what may lie ahead.

We start with familiar ground—cardiovascular risk scores—and explore how predictions only matter when they guide meaningful actions: improved blood pressure control, appropriate statin use, and lifestyle changes that truly bend the curve. But Delphi doesn’t stop at single conditions. It captures the real-world complexity of multimorbidity, mapping how diseases co-occur and unfold over time.

Delphi doesn’t “understand” biology—it recognizes patterns. Much like a weather forecast, it turns complex statistical relationships into calibrated probabilities. We break down how the model handles irregular patient histories, simultaneous diagnoses, and time-to-event forecasting—offering practical insights clinicians can use. We also explore how Delphi was validated across extensive UK and Danish datasets, and why “reliable” beats “flashy” in the real world of medicine.

One of Delphi’s most promising features? Generative timelines. By simulating possible health futures from partial records, the model creates synthetic patients—fueling research while protecting privacy.

At the core is a human question: would you want to know your likely diagnoses decades in advance? We unpack the emotional and ethical dimensions of predictive health—when foresight helps, when it overwhelms, and how to responsibly deliver these insights. If you care about AI in healthcare, predictive analytics, or the ethics of foreknowledge, this episode offers a grounded look at what’s here, what’s coming, and how to use it wisely.
