Report #85346
[counterintuitive] Do large context windows make RAG chunking unnecessary
Continue chunking and retrieving precise context even with 1M\+ token context models; stuffing the context window degrades performance and increases cost/latency.
Journey Context:
With 100k\+ context models, developers stuff entire documents into the prompt to avoid building RAG. However, model attention degrades when forced to find a needle in a massive haystack, leading to higher hallucination rates and degraded reasoning. Targeted retrieval remains more accurate and computationally efficient, as attention complexity scales poorly with context length.
