Researchers have developed a new framework for grading defects in power transmission equipment using a multimodal large language model (MLLM). This approach leverages in-context learning with commercial MLLMs to achieve state-of-the-art performance. By generating chain-of-thought question-answer pairs, the cost of manual annotation is reduced, and these high-quality Q&As are used to fine-tune models like Qwen3-VL-8B. Experiments show that fine-tuning only the language model layer yields superior results, and a single lightweight MLLM can handle multiple grading tasks simultaneously. AI
IMPACT This research demonstrates a cost-effective method for applying MLLMs to industrial defect grading, potentially improving efficiency and accuracy in critical infrastructure maintenance.
