Researchers have introduced Gen-VCoT, a novel framework designed to enhance multimodal large language models (MLLMs) by generating visual chain-of-thought (CoT) reasoning steps. Unlike existing methods that rely on text-based CoT or opaque tokens, Gen-VCoT utilizes expert vision models to produce interpretable RGB images as intermediate reasoning representations. This approach involves stages of visual grounding with SAM, geometric reasoning using Marigold depth maps, and semantic reasoning integrated with Qwen2-VL, with an adaptive router controlling the reasoning depth. While Gen-VCoT shows significant improvements in spatial and depth-related questions, its performance on simple factual queries may be impacted, and text-based CoT remains superior for certain tasks like CLEVR.
