Swiss startup Jua claims its AI weather forecasting model, EPT-2, surpasses the accuracy of leading models from Microsoft (Aurora) and Google DeepMind (Graphcast). Independent studies previously showed Aurora and Graphcast outperforming the European Centre for Medium-Range Weather Forecasts (ECMWF)'s ENS forecast, considered a global leader. Jua supports its claim with a newly published report directly comparing EPT-2's performance against these top-tier models, suggesting a potential shift in the landscape of weather forecasting accuracy and speed.
