China's National Astronomical Observatories (NAO) and Alibaba Cloud recently announced the launch of "Jinwu," the world's first solar large language model (LLM). This marks a significant step forward in the integration of solar physics research and artificial intelligence (AI) technologies. Developed using Alibaba Cloud's open-source Tongyi Qianwen framework, the model boasts over 91% accuracy in predicting M5-class solar flares, the highest global accuracy rate for this level of prediction.
This achievement not only enhances the accuracy of space weather forecasting but also provides new technological safeguards against potential Earthly impacts from solar activity. "Jinwu" leverages massive amounts of solar observation data combined with NAO's expertise in solar physics. It utilizes Tongyi Qianwen's powerful computing capabilities and natural language processing (NLP) techniques to efficiently predict solar flare occurrences. M5-class flares, being relatively strong solar events, can significantly disrupt Earth's communication systems, satellite operations, and power grids, making their accurate prediction a key focus in space weather research.

NAO provided high-quality observational data including solar magnetic fields, spectra, and multi-band imaging, while Alibaba Cloud contributed its advanced cloud computing infrastructure and AI algorithm support. Tongyi Qianwen, as an open-source large language model, provided a solid foundation for "Jinwu's" development due to its flexibility and customizability. Through deep learning and data-driven methods, the model identifies precursor characteristics of flare occurrences from historical data and predicts the probability of flare events within the next 24 to 48 hours.
Experts point out that "Jinwu's" prediction accuracy of over 91% for M5-class flares represents a significant improvement over traditional methods. Previously, international flare prediction systems based on physical and statistical models typically achieved accuracy rates between 70% and 85% for strong flares. "Jinwu," through the integration of AI, has successfully overcome this bottleneck, possibly due to its enhanced ability to capture the complex, non-linear relationships of solar activity, particularly in handling key parameters such as active region magnetic field evolution and multi-band radiation changes.
This collaboration is considered a significant endeavor in the intersection of space science and AI in China. NAO states that "Jinwu" will not only serve as a research tool but will also be gradually applied to practical space weather forecasting services, providing more reliable early warning information for aerospace, power industries, and the public. Alibaba Cloud emphasizes that Tongyi Qianwen's open-source nature makes "Jinwu" highly scalable, with potential for further optimization and extension to other astronomical research areas, such as solar wind prediction or interplanetary space weather monitoring.
However, industry insiders note that while "Jinwu" excels in predicting M5-class flares, its predictive capabilities for higher-level flares (such as X-class) and its long-term stability still require verification. Furthermore, the model's reliance on real-time data may pose challenges for its application in remote areas or environments with limited data access. The NAO and Alibaba Cloud teams state they will continue to improve model algorithms and plan to incorporate more international observational data to further enhance its comprehensiveness and robustness.
The release of the "Jinwu" LLM showcases China's technological prowess in solar physics and AI, setting a new benchmark for global space weather research. With solar cycle 25 approaching its peak, the model's timely launch may have a profound impact on humanity's understanding and response to solar activity.
