[Purpose/significance] Artificial intelligence is profoundly driving the paradigm transformation, content op⁃timization, and efficiency leap of public digital cultural services. By constructing vertical domain AI agents, an attempt is made to provide a feasible path for enhancing the efficiency of public digital cultural services through the empower⁃ment of artificial intelligence. [Method/process] Point out the specific aspects of how vertical domain AI agents em⁃power the efficiency improvement of public digital cultural services, design the construction path of vertical domain AI agents for public digital cultural services, and conduct empirical tests on the proposed path by taking the construction of vertical domain AI agents for digital cultural services at the 2025 Asian Winter Games in Harbin as an example. [Re⁃sult/conclusion] Through empirical tests, it is proved that the construction path and application scenarios of the verti⁃cal domain AI agent for public digital cultural services proposed in this study are feasible, thereby exploring an effec⁃tive solution for enhancing the efficiency of public digital cultural services through artificial intelligence based on the construction of vertical domain AI agents.
