[cost\_intel] Context window stuffing vs RAG infrastructure cost tradeoff

For tasks processing fewer than 10,000 documents or low query volume, pass the full documents into the context window. For high-volume production pipelines querying massive datasets, invest in RAG to avoid paying 100k\+ input tokens per query.

Journey Context:
There is a dogma that RAG is always better than long context. But RAG has hidden costs: embedding compute, vector DB hosting, and retrieval latency. If you have a small codebase or a low volume of queries, paying $3/million input tokens to just stuff the whole codebase \(e.g., 50k tokens = $0.15/query\) is vastly cheaper than maintaining a vector database infrastructure. However, at scale \(millions of queries on massive datasets\), the linear cost of input tokens makes RAG the only economically viable option.
