UnverifiedLimitations of RAG include that poor quality of retrieved documents, retrieval failures, and the model ignoring retrieved evidence (attention drift) can still lead to hallucinations.71% similarUnverifiedTraditional RAG systems have limitations including returning empty results when retrieval fails, inability to answer metadata questions about the knowledge base, and lack of multi-turn iterative error correction70% similarUnverifiedRAG-based memory retrieval has an inherent limitation: retrieval granularity is constrained by text chunking strategy, and similarity matching cannot perfectly capture complex causal reasoning chains and temporal dependencies68% similarUnverifiedRAG has two vulnerabilities: the model may still misread or misuse the context when processing it, and the retrieved context itself may be incorrect or irrelevant.67% similarVerifiedRAG has drawbacks including unstable retrieval precision, semantic matching deviations, and consumption of large amounts of the context window.67% similar
