[counterintuitive] large context windows eliminate the need for chunking and retrieval

Continue using chunking and targeted retrieval even with 100k\+ context models; do not dump entire document corpora into the context window blindly.

Journey Context:
With 128k\+ context windows, developers assume they can just stuff everything in. However, needle in a haystack evaluations show models suffer from severe U-shaped attention curves—they miss information in the middle of long contexts. Furthermore, processing massive contexts increases latency, cost, and the probability of conflicting information leading to confused outputs.
