[counterintuitive] more context is always better for accuracy

Curate and compress context aggressively; retrieve only the most relevant chunks and place critical information at the very beginning or end of the prompt.

Journey Context:
With massive context windows \(128k\+\), developers stuff the prompt with everything, assuming the model will find the needle. Empirical research shows LLMs suffer from 'lost in the middle' degradation: they attend strongly to the start and end of the context, but ignore information in the middle. More context also increases latency, cost, and the chance of conflicting information confusing the model. Precision in retrieval and prompt construction yields better accuracy than brute-force context expansion.
