ECMWF's AI weather model runs 10x faster at ~1000x less energy than the physics-based system.
Story
First rigorous statistical comparison of AIFS against IFS on operational ensemble data (arXiv). The energy number is the headline. AI forecasting is now operationally competitive, not just a research curiosity, and the cost structure is the reason it'll win deployment.
