The LLM usage breakdown shows Claude Sonnet dominates with 35x the cost of Haiku despite similar run counts. But the truly surprising finding mentioned in the overview is that despite being a platform designed to illuminate data relationships in external systems, it has ZERO viable joins in its own schema. I need to verify this claim about relationships to confirm this irony.",
