What happened

WeatherNext 2 is the productized successor to DeepMind and Google Research ML weather models. The company said the new model generates many scenarios much faster than the previous WeatherNext version and upgraded consumer and enterprise weather surfaces. Forecast skill claims are developer-reported. This event records operational productization rather than the earlier GraphCast and GenCast papers.
