# Anthropic publishes Contextual Retrieval guidance

> Anthropic published an engineering discussion of Contextual Retrieval, a retrieval-augmented generation approach that adds context to chunks before embedding and indexing them. The post compared retrieval strategies on its cited benchmark and discussed combining contextual embeddings with reranking, while noting accuracy remains dependent on corpus and evaluation design.

## Engineering relevance

Retrieval improvements must be measured against real documents and questions. Hypler should retain representative corpora, relevance judgments, source display checks, and regression cases instead of relying on generalized benchmark results.
