Operational AI Forecast Model Deployment (NOAA, ECMWF, Private Sector)
#1NOAA operationally deployed AI-driven global weather forecast models in 2025, joining ECMWF (which launched AIFS as an operational product in 2024), the UK Met Office, and multiple national meteorological services that have integrated AI models into operational forecast suites. These systems — including derivatives of GraphCast, Pangu-Weather, and FourCastNet — produce 10-day global forecasts in seconds at 0.25° resolution using a single GPU, replacing workflows that previously required hundreds of CPU-hours on supercomputer clusters. The 99.7% compute reduction is not merely an efficiency gain; it eliminates the primary technical justification for large operational forecasting teams whose core function was running, post-processing, and interpreting NWP output.
