Contextual Retrieval — AI Glossary

An Anthropic-developed RAG enhancement that prepends chunk-specific context (generated by an LLM) before embedding each chunk.

Overview

Contextual retrieval significantly reduces retrieval failures by adding document context that would otherwise be lost when chunks are split. Combined with hybrid search and reranking, it reduces top-20 retrieval failures by ~70% vs naive RAG.
