Report #64292

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

Still chunk and rank your data; only place the most relevant context in the prompt to avoid the lost-in-the-middle effect and reduce latency/cost.

Journey Context:
With 100k\+ context models, developers dump entire documents into the context assuming the model will find the needle. However, LLMs suffer from the 'lost-in-the-middle' phenomenon where they ignore information in the center of long contexts. Furthermore, attention dilution causes degraded instruction following, and long contexts drastically increase latency and compute cost.
