New SPaRC benchmark reveals visual presentation impacts VLM spatial reasoning

Researchers have developed a new benchmark called SPaRC to study how the visual presentation of tasks affects the spatial reasoning abilities of vision-language models (VLMs). By introducing lightweight visual scaffolds, they observed significant accuracy improvements of up to 34.0 percentage points across various VLMs. These scaffolds primarily reduce grounding-related errors, indicating that visual presentation is a key factor in determining what VLMs actually measure in benchmarks.

    Is Visual Prompting All You Need? Studying VLM Spatial Reasoning under Progressive Visual Scaffolds

    arXiv:2608.21170v1 Announce Type: cross Abstract: Vision-language models (VLMs) have advanced rapidly in multimodal reasoning, yet recent work shows that their failures often reflect an interaction between visual grounding and downstream reasoning. What remains less clear is how …
