Google's WeatherNext 3 shifts global AI forecasts to an hourly refresh News
WeatherNext 3 generates global forecasts every hour using low-latency satellite observations and station data, while retaining analysis inputs and important upper-air limitations.
The case against using transformers for physics News
Caltech's Anima Anandkumar argues that simulating the physical world at industrial resolution implies hundreds of billions to a trillion tokens of context, putting it permanently out of reach for transformers -- and that neural operators, which learn maps between functions rather than sequences, are already outrunning supercomputers on weather, climate and fusion.
Neural operators Lesson
A neural operator learns a mapping between whole functions rather than between fixed-size arrays, which lets one trained model work at any grid resolution and makes learned physics simulation orders of magnitude faster than solving the equations.
Google put the hurricane model's weights on a public bucket News
DeepMind has open-sourced WeatherNext 2 with pretrained weights, including the exact cyclone checkpoint the National Hurricane Center used operationally through the 2025 Atlantic season, plus a one-degree variant sized for a single consumer GPU.
WeatherNext called Melissa's Category 5 landfall five days out News
Google DeepMind's WeatherNext predicted Hurricane Melissa's Category 5 landfall in Jamaica five days ahead at 80% confidence, and its five-day track forecasts averaged about 140 kilometres closer than the European ensemble -- roughly a day and a half of extra warning.
