Google DeepMind has introduced WeatherNext 3, calling it its most advanced and accurate global weather AI model to date.
Replacing the Supercomputer Forecast
Traditional global forecasts come from numerical weather prediction — physics equations simulated on supercomputers, a process that takes hours per run. WeatherNext replaces that pipeline with a neural network that generates forecasts near-instantly, and DeepMind says the third generation delivers its best accuracy yet across standard forecasting benchmarks.
The August generation of WeatherNext already demonstrated a breakthrough in forecasting cyclones; generation 3 extends that lead across the board.
The launch lands in the same DeepMind science wave as AlphaGenome Atlas. Read the full announcement on the Google blog.
