[counterintuitive] more context window usage improves accuracy

Optimize context by only including strictly relevant information. Place critical instructions at the very beginning or end of the prompt. Use RAG to filter rather than dump entire documents.

Journey Context:
Developers stuff the context window thinking more data equals better decisions. However, LLMs suffer from the 'lost in the middle' effect and attention dilution. Irrelevant context degrades performance and increases latency and cost. A model with a 128k context window does not uniformly attend to all 128k tokens; it prioritizes the start and end of the sequence.
