llm pipeline

Summarizing a 200-page contract is not one LLM call: it is chunking, hierarchical reduction, and a faithfulness check so you never invent facts. Learn the map-reduce pattern, when long-context beats it, and how to evaluate summaries at scale.

Moderating billions of items a day with an LLM on every one is too slow and too expensive. Learn the tiered funnel (cheap classifier then LLM then human), how to tune thresholds for precision versus recall, and how to keep up with adversaries.
