- How do you decide how many chunks (top-k) to retrieve in RAG?
Too few chunks risk missing the answer. Too many add noise, raise cost and can bury the useful passage. Choose k by measuring recall and answer quality on test questions, and often retrieve many, rerank, and pass only a handful to the model.
