Report #43039

[counterintuitive] Should I stuff the entire document into the LLM context window instead of chunking for RAG

Continue chunking and retrieving highly relevant segments rather than stuffing entire documents, even with large context windows, to maintain high attention quality.

Journey Context:
With 100k\+ context windows, developers assume they can just dump whole documents into the prompt and skip retrieval logic. However, models suffer from 'attention dilution' \(Lost in the Middle\). When forced to find a needle in a massive haystack, they miss information or hallucinate. Chunking and precise retrieval remain necessary to guide the model's attention to the exact relevant data, reducing cost and increasing accuracy.
