Report #73509

[counterintuitive] Larger context windows mean you should pass all available documents to the model

Curate and rank retrieved context aggressively; place the most critical information at the very beginning or end of the prompt.

Journey Context:
With 128k\+ context windows, developers stuff all retrieved chunks into the prompt assuming more data equals better answers. Research shows LLMs suffer from 'Lost in the Middle' degradation: they attend heavily to the beginning and end of the context, but accuracy plummets for information located in the middle. Passing 50 irrelevant chunks degrades performance on the 1 relevant chunk compared to just passing the 1 relevant chunk.
