The advance was achieved by a Chinese-developed weather forecasting model running on Sugon 8,000, a massive home-grown computing system built entirely with domestically made [AI chips](https://www.scmp.com/news/china/science/article/3360328/chinas-optical-chip-breakthrough-boosts-ai-speed-100-fold-using-fraction-compute-power?module=inline&pgtype=article). Most major global forecasting systems have resolutions of roughly 5km to 10km, according to the China Meteorological Administration and Beijing-based computing company Sugon, which jointly announced the results on Tuesday. For instance, the Global Forecast System – the main global weather model run by the US National Weather Service – has a maximum resolution of about 13km.
