Researchers have introduced PivotMerge, a novel framework designed to integrate the cross-modal alignment capabilities of different multimodal large language models (MLLMs). This approach addresses challenges in merging pre-trained models, specifically cross-domain parameter interference and uneven layer contributions to alignment. PivotMerge utilizes shared-space decomposition and filtering, along with alignment-guided layer-wise merging, to effectively combine these expert models. Experiments on multimodal benchmarks indicate that PivotMerge surpasses existing methods in its ability to bridge heterogeneous pre-training. AI
