Region4Web: Rethinking Observation Space Granularity for Web Agents
Region4Web introduces a novel framework that reorganizes how AI web agents perceive and process web pages by shifting from element-level to functional region-level observation granularity. The approach, validated on WebArena benchmark, reduces observation length while improving task success rates across multiple LLM models, demonstrating that hierarchical abstraction of page structure yields more efficient agent performance.
