Model Merging for Medical LVLMs: A Benchmark and a Winner-Take-All Approach

arXiv:2607.15661v1 Announce Type: new Abstract: Large vision-language models (LVLMs) can be adapted to specialized medical imaging tasks via parameter-efficient fine-tuning approaches such as low-rank adaptation (LoRA), leading to a growing ecosystem of expert models tailored to specific imaging modalities and clinical scenarios. However, deploying multiple expert LVLMs in practice incurs substantial computational and operational overhead. Model merging provides a promising solution by consolida...
