Researchers have developed GeoSolver, a new framework designed to improve the reasoning capabilities of Vision-Language Models (VLMs) in remote sensing. The system utilizes a novel process reward model (PRM) trained on a large-scale dataset called Geo-PRM-2M, which provides fine-grained feedback on the visual faithfulness of intermediate reasoning steps. By integrating this PRM with a reinforcement learning algorithm, GeoSolver-9B achieves state-of-the-art performance on remote sensing benchmarks and demonstrates robust test-time scaling capabilities, enhancing both its own performance and that of general-purpose VLMs. AI
