UnverifiedLarge models have ingested vast amounts of general internet knowledge through pre-training, but pre-training data often does not include specialized knowledge from vertical domains; RAG improves answer accuracy in vertical scenarios by feeding enterprise private documents to the model as reference material.77% 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76% similarUnverifiedCompared with letting a model answer solely based on parameters memorized during training, RAG can significantly reduce hallucinations, and because answers have clear provenance, it can provide citation links, making auditing and updating easier, requiring only modifying documents without retraining the model.75% similarUnverifiedThe underlying model training data of the three AI engines, the real-time index sources for retrieval-augmented generation (RAG), and the preference alignment strategies in the post-training stage all differ, and this is the key technical background leading to the divergence in engine recommendations.74% similarVerifiedRAG can supplement knowledge beyond the training data cutoff date in real time, avoiding expensive full fine-tuning of the model.73% similar
