This sounds obvious, but the bottleneck is invisible at the prototype stage. A single model call is cheap, and it works well on the 20 documents in your test set. Then you hit production traffic. The failure mode is usually pretty similar across teams: tens of thousands of LLM calls per day, tens of m
