On July 17, at the 2026 World Artificial Intelligence Conference (WAIC) Meteorological Forum, the China Meteorological Administration (CMA) unveiled Fenghe, a Large Language Model-Based Al MeteorologicalService System, marking the commencement of its Global Open-Source Initiative.
The commencement aims to advance meteorological AI worldwide and support global cooperation on disaster prevention and mitigation as well as sustainable development, and bring together developers, research institutions and international partners to build a collaborative ecosystem.
CMA is actively promoting the in-depth integration between AI and meteorological services to explore smarter, more efficient and inclusive new models. Co-developed by the CMA Public Meteorological Service Centre, the Xiong'an Artificial Intelligence Research Institute, Z.AI Co., Ltd. and other entities, Fenghe is the world's first open-source meteorological large language model with a hundred-billion-parameter scale. It delivers intelligent support for weather analysis, risk assessment, and meteorological services. Based on the Earth system data, Fenghe has been trained on 50 million tokens of high-quality meteorological service corpus and incorporates authoritative meteorological datasets. Having completed the filing for generative Artificial Intelligence (AI), it enables safe and controllable model applications for users.
