360CityArena: A Realistic Virtual Urban Navigation Benchmark for Embodied Agents

Hugging Face Daily Papers ↗ · 2026-08-09 Cached

360CityArena is a photorealistic urban navigation benchmark built from 360-degree videos of Tokyo's Akihabara district. It evaluates embodied agents' environment understanding, path reasoning, and spatial reasoning, showing that even strong LMM-based agents like Gemini 2.5 Flash perform far below human level.
