[counterintuitive] more context always better RAG

Optimize for high signal-to-noise ratio in context windows; strictly rank and truncate retrieved chunks, as irrelevant context degrades reasoning.

Journey Context:
Developers often stuff the context window with top-K retrieved documents, assuming more data gives the model a better foundation. This ignores the 'Lost in the Middle' phenomenon, where LLMs fail to utilize information located in the middle of long contexts. Furthermore, irrelevant context increases the probability of the model hallucinating a synthesis of conflicting information, while also inflating latency and cost. Fewer, highly relevant chunks consistently outperform large volumes of mediocre context.
