It takes 8 minutes to produce a 15 day forecast. That's actually quite a long time for an AI model. I should probably read the paper to find out why but does anyone know? Is the model predicting the weather in 10 minutes time and just run iteratively 2000 times for a 14 day forecast?

Sure, but it's several orders of magnitudes smaller than the parent, physics-based weather model it's emulating, which may take 2-3 hours of wallclock time on an HPC system with a few thousand cores allocated to running it. > I should probably read the paper to find out why but does anyone know? Is the model predicting the weather in 10 minutes time and just run iteratively 2000 times for a 14 day forecast? Basically, yes. It's run autoregressively but in 6-hour forecast intervals. The added complexity is the iterative nature of the diffusion process used to generate each of those forecast intervals.
