GenCast combines a cutting-edge diffusion model with the full sweep of historical global weather data. Unlike some AI models that borrow techniques from image or music generation, GenCast is tuned to Earth’s spherical geometry and the subtle dance of the atmosphere. Trained on four decades of temperature, wind, and pressure readings, it has learned to tease out complex patterns that affect local snowfall from the largest weather systems. Impressively, it operates at a resolution fine enough—about a quarter-degree latitude and longitude—to broadly capture the shifting moods of the mountains. Even more remarkable is its speed: producing a 15-day ensemble forecast in around eight minutes, a fraction of the time traditional physics-based models require.
Looking forward to seeing this AI weather forecasting program put to the test : )~
Once the AI model was trained up, it was then asked to predict the weather for 15-day periods in 2019. When compared to the actual weather that occurred in that year, GenCast was 97.2% more accurate than the ECMWF predictions. When the window of the prediction time was narrowed to just 36 hours, GenCast did even better – it was 99.8% more accurate than ECMWF. Both metrics best Google's previous weather prediction program, known as GraphCast.

This is Googles scientific paper on "Gencast" that is published for peer science review with open code provided.
Probabilistic weather forecasting with machine learning - Nature
GenCast, a probabilistic weather model using artificial intelligence for weather forecasting, has greater skill and speed than the top operational medium-range weather forecast in the world and provides probabilistic, rather than deterministic, forecasts.
