Researchers have developed SpatialThinker, a novel multimodal large language model designed to enhance spatial reasoning capabilities. This model integrates scene graph generation directly into its reasoning process, utilizing dense reinforcement learning rewards to simulate human-like spatial perception. SpatialThinker has demonstrated strong performance, with its 7B parameter version matching GPT-5 and outperforming GPT-4o on various benchmarks, while the 30B version surpasses both GPT-5 and Claude 4 Sonnet, particularly in spatial understanding with limited training data.
