UrbanGround: Testing MLLM Agents in Real-Scale Hong Kong City Navigation

Researchers from Shanghai Jiao Tong University, NUS, Meituan, and others built UrbanGround, a real-scale interactive Hong Kong environment using 3D geographic data, to evaluate MLLM agents on local perception, navigation persistence, and dynamic adaptation, revealing models excel at local tasks but fail at long-range navigation and dynamic recovery.
