WeatherNext 2
WeatherNext 2: a Functional Generative Network makes hundreds of coherent forecast scenarios in under a minute on one TPU, beating v1 on 99.9% of variables.
Injects noise into the model architecture so single-variable marginals and joint fields stay physically consistent. Data is in Earth Engine and BigQuery, with Vertex AI early access; it upgrades weather in Search, Gemini, Pixel and Maps.
