S-Space: Exploring Spatial Workspace in Multimodal Language Models

What happened: A paper titled S-Space describes a linear representation subspace in multimodal language models where object-token representations encode continuous coordinates along horizontal, vertical, and distance axes. Why it matters: The authors use S-Space as a diagnostic tool and report that MLLMs can form capable spatial representations but fall short in the spatial transformations needed to reason reliably across viewpoint changes. Note: the content contains no concrete figures such as revenue, percentages, prices, or volumes, so no Key numbers line is included.
