Researchers have developed two novel approaches to enhance spatial reasoning in large vision-language models (LVLMs). One method, Soft Spatial Reasoning, introduces a "soft thinking" framework that allows models to maintain a continuous soft state by mixing token embeddings at each reasoning step, rather than committing to a single discrete token. This approach, which includes an AdaptSoft controller to manage the degree of softness, has shown improved performance on various spatial benchmarks. The second approach, Spatial-OPSD, utilizes label-free self-distillation to improve spatial reasoning without relying on ground-truth answers. This framework uses automatically obtainable spatial priors like depth and 3D relations to train a student model, enabling repeated self-improvement and achieving state-of-the-art results among open-source models on several spatial reasoning benchmarks.
