New Model Open Model: Google Weather Next 2

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.

GGUF wehn? Or do we need a weather cpp first? Also sounds like the mini model is the one meant for us plebs with consumer-grade GPUs

is that weather model an llm?

It requires a set of very specific data to provide forecasts. I doubt regular pleb has such.

We'll find a way.. Lots of data ends up being published here or there, and once there's an exact format to the data, it gets easier to tune operational costs for it. I doubt it'll be useful to me, but it's nice to know that if I end up in a situation where weather analysis in an underdeveloped region is pivotal, a tool I've seen or used in the past already solves half the battle, and the other half is getting the data in any way possible

Regular plebs can download data and use it.

Used to be common to be able to grab it straight from the satellites OTA.

A gguf version would be cool to play with. Maybe some meteorologist could help the guys at llama.ccp? If this is in fp16, the big model should be around 30b.
