Researchers have introduced S-Agent, a novel framework designed to enhance visual language models (VLMs) for spatial reasoning in 3D environments. S-Agent integrates temporal memory and a hierarchy of spatial tools to enable continuous understanding of 3D worlds from multi-view imagery, moving beyond static, frame-level analysis. The framework allows VLMs to act as semantic planners, deciding what evidence is needed, while spatial tools ground objects in 2D, lift them to 3D, and aggregate this into spatial knowledge. Experiments show S-Agent improves both open-source and closed-source VLMs without retraining, and a fine-tuned version, S-Agent-8B, demonstrates performance comparable to advanced models like GPT-5.4 and Gemini 3.
