On October 28, the China Meteorological Administration launched "Fenghe", China's first 100-billion-parameter meteorological service vertical model. This model was independently developed based on a general large language model, deeply integrating professional meteorological knowledge with artificial intelligence technology. "Fenghe" is a large model for public and industry meteorological services, capable of addressing issues such as insufficiently precise understanding of meteorological service needs, lack of speciality in generated content, and shallow application scenarios in existing general models. It provides reliable, usable, and trustworthy meteorological decision-making information.
