China launches global open-source initiative for AI weather model

SHANGHAI, July 17 (Xinhua) -- China on Friday unveiled Fenghe, an open-source large language model dedicated to meteorological services, and launched a global open-source initiative for this model.

The announcement was made by the China Meteorological Administration (CMA) at a meteorological sub-forum of the 2026 World Artificial Intelligence Conference and High-Level Meeting on Global AI Governance in east China's Shanghai.

Developed by the CMA, Fenghe is trained on 50 million tokens of meteorological service data and integrated with authoritative weather datasets to support weather forecasting, risk assessment and meteorological services.

According to the CMA, Fenghe provides personalized weather information, service recommendations and risk alerts for users in China. Its international version has also been incorporated into the United Nations' Early Warnings for All initiative, offering weather consultation and risk analysis services in Chinese and English.

The global open-source initiative aims to enable developers worldwide to integrate the model into a wide range of applications and promote an open AI ecosystem for meteorological services.
