Briefings
WM-VLM, a pretrained VLM with a lightweight world model branch, consistently outperforms its supervised fine-tuned backbone on 2D and 3D mental rotation tasks by up to 39.25 percentage points. The model solves spatial problems by reasoning with both text and generated visual states, demonstrating that internal world models enable VLMs to reason in both language and visual space.
Key points
- WM-VLM consistently outperforms the supervised fine-tuned backbone on 2D and 3D mental rotation tasks by up to 39.25 percentage points.
- Performance gains depend on the generated visual states, as removing or corrupting them sharply reduces model performance.
Context and limitations
Results are from a single study published in 2026; performance gains may vary across different datasets and model architectures.
