The advantage of RAG architecture is that new knowledge can be injected without retraining the model, but the trade-off is that prompt length (number of input tokens) grows significantly as retrieved content increases.

UnverifiedThe core idea of RAG is to decouple parametric knowledge from non-parametric knowledge, reducing the cost of knowledge updates from full fine-tuning to incremental updates of the document repository, while providing traceable citation references.75% similarVerifiedThe essence of RAG is to expand input information; it does not change the model's internal weights or reasoning habits.75% similarVerifiedThe essence of RAG is decoupling parametric knowledge (knowledge solidified in model weights) from non-parametric knowledge (an enterprise's own externally updatable knowledge base).72% similarUnverifiedThe advantage of RAG over purely generative models is that answers have explicit document sources that can be traced, and the knowledge base can be updated independently without retraining the model.72% similar
