# NVIDIA's Earth2Studio Unifies Every Major AI Weather Model in Four Lines of Code

> NVIDIA's open-source Earth2Studio gives Python developers a unified API to run, chain, and benchmark state-of-the-art AI weather models in minutes

[Earth2Studio](https://github.com/NVIDIA/earth2studio) is NVIDIA's open-source Python framework for building AI-driven weather and climate inference pipelines. It sits above the raw model weights and data formats, giving you a composable toolkit to fetch atmospheric data, run forecasts with pre-trained models, apply diagnostics, and write outputs , all through a single unified API. The repo has crossed 1,000 GitHub stars and is actively maintained, with version 0.15.0 shipping recently and a 0.16.0 alpha already in progress.

## The problem it solves

AI weather forecasting has exploded in the last two years. GraphCast, Pangu-Weather, FourCastNet, AIFS, Aurora , each comes with its own checkpoint format, coordinate system, data preprocessing logic, and inference loop. Stitching them together for a real workflow means writing a lot of glue code. Earth2Studio replaces that glue with a shared vocabulary and protocol, so swapping one model for another is a one-line change.

The framework is built around five composable component types:

* **Prognostic models** , time-stepping models that auto-regressively roll out atmospheric fields into the future (typically 6 hours per step)
* **Diagnostic models** , time-independent transforms that derive new quantities from a forecast (precipitation, wind gusts, tropical cyclone tracks, solar radiation)
* **Data sources** , standardized connectors to operational feeds (GFS, IFS, HRRR), reanalysis archives (ERA5, ARCO), and satellite observations
