Why accuracy, latency, and cost can't all be optimized together in document extraction.
Bad chunk boundaries tank RAG accuracy more than model choice.
System architecture determines which model matters, not benchmark scores alone.
Graph-based methods beat geometric sorting on complex document layouts.
Breaking documents into logical parts prevents extraction errors downstream.
Fixing parsing errors early prevents silent failures downstream in agent systems.
Hallucinations that pass validation checks pose bigger risks than raw accuracy metrics reveal.
