[counterintuitive] Does increasing context window length improve LLM accuracy

Curate context aggressively; place critical information at the beginning or end of the prompt, not the middle, and limit context to only what is strictly necessary.

Journey Context:
Developers stuff the 128k/200k context window thinking more data = better answers. Research shows LLMs suffer from severe 'lost in the middle' degradation. If the answer relies on a document in the middle of a massive prompt, accuracy plummets. More context also increases latency and cost, and increases the chance of conflicting information confusing the model. A smaller, highly curated context window almost always outperforms a massive, noisy one.
