While traditional compute constraints limit standard weather updates to six-hour intervals, WeatherNext 3 ingests real-time satellite data directly to launch a brand-new forecast every single hour.

By training directly on raw weather station observations, the system captures localized microclimates across typically underserved areas. It also delivers a 5 times resolution boost in temperature forecasts - from 25km down to 5km - in a single pass. 🏔️

Predicting rain accurately is notoriously difficult for global weather models, with previous methods producing blurry estimates or missing severe storm boundaries. WeatherNext 3 achieves a major leap in global precipitation forecasting, delivering up to a 50% reduction in error - with the greatest improvements in regions where forecasts have historically been less reliable.
