CRAG vs RAG: How Corrective RAG Improves Retrieval-Augmented Generation

RAG retrieves relevant information and sends it to a language model. CRAG adds a correction step that evaluates whether the retrieved information is reliable before the model generates an answer. That single addition is the core of the difference. Retrieval-Augmented Generation (RAG) grounds a large language model in external knowledge so it answers from your […]

RAG System Components: Architecture, Pipeline, and Best Practices

The main components of a RAG system are the knowledge sources, ingestion pipeline, document parser, chunking strategy, embedding model, vector database or search index, retriever, reranker, prompt and context builder, large language model, response generator, citation layer, evaluation system, and security controls. Together, these components let a Retrieval-Augmented Generation system find trusted information, pass the […]
