Chinese scientists unveiled the world's first multimodal geographic science model, "Sigma Geography," which can answer professional geographic questions, analyze geographic literature, query geographic data resources, and even create thematic maps.

Compared to general-purpose large language models, it boasts an approximately 31 percent increase in accuracy within the field of geography, the research team claimed.

Sigma Geography was jointly developed by the Institute of Geographic Sciences and Natural Resources Research, the Institute of Tibetan Plateau Research, and the Institute of Automation of the Chinese Academy of Sciences.
