GenCast: Google DeepMind’s AI Revolutionizes Weather Forecasting

Google DeepMind's GenCast, trained on 40 years of ECMWF data, outperforms traditional ENS forecasts 97.2% of the time for 15-day predictions. Running in just eight minutes on a single TPU v5, GenCast excels at predicting extreme weather and offers probabilistic forecasts. Set to integrate with Google Search and Maps, it’s also open-source for researchers. While not yet perfect—cyclone intensity remains tricky—John Wheeler hints AI could soon give human forecasters a run for their money.
