Problem
Document processing looks simple until every page, chunk, retry, and summary runs through a premium long-context model. Once volume grows, output tokens and cache misses dominate the bill.
Architecture
The workload moved to an open-model extraction lane with a batch route for non-urgent jobs. Frontier models were used for schema design, evaluator samples, and edge cases that changed business decisions.
Cost control
The team measured accepted outputs per provider, cache hit rates, and retry volume. Provider choice was made after quality sampling, not from sticker prices alone.
