Unverified50% confidenceFactExact time
Large models' parametric knowledge only covers content before the training corpus cutoff and does not include enterprise internal documents, databases, and tickets; the context window (such as 8K, 128K tokens) determines how much information can be stuffed in at a time, and anything beyond that will be truncated.

UnverifiedParametric knowledge is fixed in model weights and cannot be updated without retraining once training is complete; non-parametric knowledge is stored in external databases and can be added, deleted, or modified at any time.75% similarVerifiedPre-training data for large models has a clear cutoff date, the model internally contains no enterprise private data, and hallucinations occur when directly queried about enterprise private information.74% similarVerifiedLarge language models have a knowledge cutoff in their training data, meaning they only possess information available before the training cutoff date.74% similarUnverified大语言模型对自身身份的报告依赖训练数据和系统提示中的信息注入，并非对运行时环境的直接读取，因此让模型自述身份存在技术局限69% similarUnverified当任务要求访问模型训练截止日期之后的信息、精确数值计算或处理外部文件时，提示词工程无济于事，这是工具调用和RAG出现的根本原因69% similar
