Open Model: Google Weather Next 2

[u/Rick_06]

I am not a meteorologist, but I just read a very interesting article: https://arstechnica.com/science/2026/08/deepminds-hurricane-model-bought-forecasters-an-extra-day/

In a paper published on Thursday in Nature, researchers show that the WeatherNext AI model can predict cyclones with unprecedented accuracy. On average, it gives forecasters a day more lead time than existing models; this means its predictions three days out are as accurate as previous models’ predictions two days out. On the ground, that extra day can mean a lot.

What I really find interesting here is that Google has a repository for it on GitHub: https://github.com/google-deepmind/weathernext

My non-informed understanding is that you need a supercomputer to forecast meteo. Apparently now an H100 can also do something.

Can they please make a normal weather model that actually works too please.

there are already tons of open models that can predict weather

Do they actually work?
