Google DeepMind's new AI model is the best yet at weather forecasting

Google DeepMind isn't the only big tech firm that is applying AI to weather forecasting. And in 2023 Huawei developed its Pangu-Weather model, which trained on 39 years of data. It produces deterministic forecasts--those providing a single number rather than a range, like a prediction that tomorrow will have a temperature of 30 F or 0.7 inches of rainfall. GenCast differs from Pangu-Weather in that it produces probabilistic forecasts--likelihoods for various weather outcomes rather than precise predictions. For example, the forecast might be "There is a 40% chance of the temperature hitting a low of 30 F" or "There is a 60% chance of 0.7 inches of rainfall tomorrow."
