Google DeepMind and Google Research launched WeatherNext 3 on September 3, producing hourly forecasts at up to 5-kilometer resolution against WeatherNext 2's 25-kilometer six-hour grid, roughly five times sharper. Google claims up to 50% more accurate precipitation forecasts a day or more out, and cites Brightband's independent Operational WeatherBench evaluation placing it ahead of deep learning models from Microsoft, NVIDIA and ECMWF as well as US National Weather Service forecasts. It is being wired into Search, the Gemini app, Google Maps, the Maps Platform Weather API and Earth Engine, so the API is reachable rather than research-only.
