[counterintuitive] Is more context always better for LLM accuracy

Place critical instructions and key documents at the very beginning or end of the prompt context; use targeted retrieval over brute-force context stuffing.

Journey Context:
Developers maximize context window usage, assuming more information yields better decisions. Empirical research shows LLMs suffer from 'lost in the middle' degradation: they attend strongly to the beginning and end of the context window but ignore or forget information in the middle. Stuffing the context increases cost, latency, and attention dilution, actually reducing accuracy on specific retrieval tasks.
