How to run it

On your own serverWeights are downloaded from Hugging Face and served with vLLM (load and API) or llama.cpp (modest hardware). The model then runs in a closed network with no per-request fees.

I can set this up end to end: pick the model size, deploy it on your server and connect it to your systems.

Frequently asked questions

Can Google DeepMind GraphCast / GenCast / WeatherNext 2 be used in a commercial project?

Yes. License: Code — Apache 2.0, weights — CC-BY 4.0 (since 06.08.2026; previously the weights were non-commercial). It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does Google DeepMind GraphCast / GenCast / WeatherNext 2 need?

At minimum: One GPU with 16–80 GB — mid-size versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.

Does Google DeepMind GraphCast / GenCast / WeatherNext 2 support Russian?

Language does not matter for this model: it does not work with text.

Where can I download Google DeepMind GraphCast / GenCast / WeatherNext 2 and what does it cost?

The Google DeepMind GraphCast / GenCast / WeatherNext 2 weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.

How I deploy it for clients

  1. SelectionI pick the model size for your task and hardware and test it on your examples.
  2. DeploymentI deploy it on your server or in a closed network and provide an API.
  3. Fine-tuningI fine-tune it on your data (LoRA) or connect a knowledge base — whichever is cheaper for the task.
  4. IntegrationI connect it to your CRM, ERP, bot, website or team chat and set up monitoring.
