## AI overview

WeatherNext is an AI weather-forecasting model that uses Functional Generative Networks to produce large ensembles of predictions and capture uncertainty. It generates 15-day forecasts in under a minute on a TPU, supports cyclone forecasting at relatively coarse resolution, and is being open sourced with its code and model weights for research and operational use.
