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.

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.
