Researchers have developed a novel method to fingerprint large language models (LLMs) by analyzing the standard deviation distributions of their attention parameter matrices. This technique creates a unique signature that remains stable even after extensive continued training, allowing for reliable identification of model lineage and detection of copyright infringement. The study uncovered evidence suggesting that Huawei's Pangu Pro MoE model may have been derived from Qwen-2.5 14B through upcycling, indicating potential model plagiarism. AI
