Epic recently unveiled Comet, a new AI model trained on 118 million patient records to predict future health events. The scale is unprecedented, and its initial ability to outperform specialised models is a huge leap forward for clinical AI.

But what is it really learning from our messy, real-world data? In this today's episode, we break down why Comet is a landmark achievement but also an important wake-up call. We explore the challenges of "semantic drift" and documentation artifacts, and why the model's success will ultimately depend on an organisation's own data quality.

Is Comet a true crystal ball, or a reflection of medicine's past?
