VSI-Bench

VSI-Bench is a benchmark for understanding where things are in space. The official description says: "VSI-Bench as evaluated on the LFM3-VL-2B card (vision benchmark, with-thinking setting): Embodied reasoning category, with-thinking column". Below we describe in simple words what benchmarks of this type generally examine.

VSI-Bench measures understanding where things are in space. In detail, it checks:

• locating and pointing to regions in images
• reasoning about positions, counts and relations between objects
• 3D-aware questions such as depth, perspective and room layout
• grounded perception tasks that must stay anchored to pixel locations

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Official methodology note: VSI-Bench as evaluated on the LFM3-VL-2B card (vision benchmark, with-thinking setting): Embodied reasoning category, with-thinking column. Visual-Spatial Intelligence benchmark; no inventory match.

What is the VSI-Bench benchmark?

VSI-Bench is a benchmark for understanding where things are in space.

What does VSI-Bench test?

VSI-Bench mainly measures understanding where things are in space. Concretely, it checks: locating and pointing to regions in images; reasoning about positions, counts and relations between objects; 3D-aware questions such as depth, perspective and room layout.

How is the VSI-Bench score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better. The declared maximum score of this benchmark is 100.0.

Where do I get VSI-Bench data and scores?
