Summary A

You can slash production LLM costs and latency by aggressively pruning RAG context down to only the exact sentences or tokens required to answer the query, rather than feeding raw, bloated document chunks to the model. This eliminates costly noise and token overhead, directly preventing performance degradation from long-context needle-in-a-haystack issues. For systems shipping at scale, implementing this precise context-trimming step immediately lowers API costs and speeds up response times without sacrificing retrieval accuracy.
