UnverifiedFailure of vector indexes to reflect data changes in a timely manner leads to two types of problems: stale retrieval (generating answers based on outdated documents) and ghost data (source documents have been deleted but vectors remain in the index and are still retrieved).72% similarUnverifiedCost reduction often comes with quality trade-offs: shorter context may cause the model to miss critical information, and more aggressive caching may introduce stale data.72% similarUnverifiedWhen documents are processed by an LLM as equally weighted factual sources, their staleness gets amplified into concrete incorrect answers.71% similarUnverifiedIn standard vector databases and RAG solutions, conflicting facts are silently overwritten, causing decision history to disappear with zero provenance.71% similarUnverifiedWhen the history contains updates and contradictions, pure retrieval solutions will fail—even if the retrieval itself is perfect, the returned answer may still be wrong.71% similar
