[counterintuitive] Does adding more context to the prompt improve LLM accuracy

Place critical instructions and retrieved documents at the beginning or end of the context window; aggressively prune irrelevant context to avoid the 'lost in the middle' effect and increased latency.

Journey Context:
Developers stuff prompts with as much text as possible, assuming the LLM processes all tokens equally. In reality, LLMs suffer from 'lost in the middle' degradation where they ignore information in the middle of long contexts. Furthermore, longer contexts increase the KV cache size, significantly slowing down generation \(time-per-token\) and increasing cost without proportional accuracy gains. Less is often more.
