Shanghai's Municipal Planning and Natural Resources Bureau launched the "Mowan Shikong - Open City" OPC community on Fuxing Island on October 20, together with partners including SenseTime's SenseCore infrastructure unit. According to SenseTime's official account of the launch, the platform is built on the Yunyuxingkong model, described as the country's first domain foundation model for planning and natural resources, assembled from roughly 13,000 high-quality question-answer pairs and 1.5 billion tokens of corpus covering planning and design, surveying and mapping, and natural resources. The company says the platform marks the first time a Chinese city has opened city-level, desensitized spatiotemporal data to the public. Four kinds of assets are meant to be contributed over time: desensitized data; models and compute, including compute quotas offered to public users; knowledge and corpus such as policy documents and technical standards; and reusable skills and agents for spatial recognition, map queries, spatial analysis, map output and report generation. A PC version of the community is online for trial.
Our takeThe load-bearing part is the interface, not the data volume: once a city's geometry, policies and reusable skills are packaged as callable assets, outside developers can test whether a domain model's answers match the record, which is something a demo cannot show. The open question is what 'desensitized' removes, because spatial data often identifies a place through geometry rather than names. Whether the community publishes its question-answer pairs and retrieval setup will decide if results can be checked by anyone but the builder.
