AI Model Improves Accuracy of Five-Day Regional Weather Forecasting

Swiss startup says its AI weather forecaster beats Microsoft, Google

Swiss startup Jua has launched an AI-powered weather forecaster that it says beats leading models from tech giants — potentially making it the world’s most accurate weather forecasting system. Jua claims its model — dubbed EPT-2 — is faster and more accurate than both Microsoft’s Aurora and Google DeepMind’s Graphcast. In separate, peer-reviewed studies, both of those models were shown to be more accurate than the European Centre for Medium-Rang…
