[counterintuitive] maximize context length for better accuracy

Keep contexts as concise as possible, placing critical information at the very beginning or end of the prompt. Use retrieval to filter, not just to stuff the context window.

Journey Context:
With the advent of 100k\+ context windows, developers often stuff as much retrieved text as possible into the prompt, assuming more context gives the model more to work with. This ignores the 'Lost in the Middle' phenomenon: LLMs disproportionately attend to the beginning and end of the context window and degrade significantly in recalling information placed in the middle. Furthermore, longer contexts increase latency, cost, and the chance of the model getting confused by conflicting information. Concise, highly relevant context consistently outperforms massive, noisy context dumps.
