The “Shanhai AI” educational system is a basic intelligent educational auxiliary system which faces primary and secondary school teaching scenarios, which was initiated for development in 2019. Based on the concept of multi-scenario interconnection empowered by DeepSeek, following the design philosophy of “multiple intelligent agents + vertical integration + horizontal integration”, leveraging the advantages of DeepSeek’s natural language processing and its lightweight deployment characteristics, the “Shanhai AI” educational system was upgraded to the “Shanhai AI” regional intelligent education system in 2024. “Shanhai AI” regional intelligent education system provided three types of intelligent agents: “Shanhai AI Study Companion” focusing on dynamic knowledge push and weak point intervention, “Shanhai AI Teaching Assistant” serving for lesson plan generation and cross-disciplinary curriculum design, and “Shanhai AI Manager” undertaking intelligent evaluation, dynamic optimization of resources, and security warnings. These three types of intelligent agents have achieved an effect of “1+1+1>3”, through their collaborative actions. The application effectiveness of the “Shanhai AI” regional intelligent education system indicated that this system enabled flexible autonomous learning, provided diverse teaching assistance, and was conducive to evidence-based governance decisions, providing a reusable technical paradigm for regional education empowered by large language models.
