VerifiedA model's knowledge is frozen in the parameter weights at training time and cannot perceive the current time or access real-time data; this is known as the knowledge cutoff problem.74% similarUnverifiedGeneral large language models cannot carry enterprise-specific ontological prior knowledge, and RAG systems can retrieve information but struggle to convert it into executable actions.74% similarUnverifiedWhen a model fails to correctly invoke retrieval tools or determines that a question does not require a search, it falls back to answering from training data, thereby exposing the knowledge cutoff issue.72% similarUnverified当前大语言模型训练数据存在时间截止点(Knowledge Cutoff)，无法感知截止日期后出现的新词汇或网络梗，RAG可通过检索外部知识补充最新信息72% similarVerifiedRetrieval-Augmented Generation (RAG) cannot completely eliminate hallucinations, as the model may still misinterpret retrieved documents or fill in gaps on its own when retrieval results are insufficient.71% similar
