Researchers have introduced MentalThink, a novel paradigm for multimodal large language models (MLLMs) that enables "mental" visualization through the generation and interpretation of Scalable Vector Graphics (SVG) code. This think-with-SVG pipeline allows models to create structured visual representations, enabling them to externalize spatial hypotheses, inspect them via rendering, and reason within a defined geometric space. A two-stage training process, combining supervised fine-tuning and reinforcement learning, was used to develop this system. Evaluations show MentalThink significantly improves performance on spatial understanding and reasoning tasks, achieving high scores on benchmarks like VSIBench and MindCube. AI
