Overpay shows how much more you pay than the best-value model that clears the quality bar (marked ★) — the best-value good-enough option. "16x" means you overpay 16× — 16× that reference for no quality benefit above the bar. Typical call shape for this task: 3057 input tokens → 5138 output tokens, EMA-tracked from production traffic. Cost is the observed, all-in $ per 1,000 task runs: each model's own measured usage on this task — output verbosity, thinking/reasoning tokens, cache reads and writes, and the spend on its billed failures — priced at current list rates and adjusted by the billing overhead we actually reconcile against provider invoices. Models that answer tersely cost what they actually cost; models that think at length pay for it. Not comparable to providers' advertised $/1M list rates — this is what running the task costs, not a per-token price.

Use only the supplied document and cited sources. Apply document_profile for terminology and legal or structural qualifiers and analysis_profile for the requested dimensions and decision lens. Distinguish source fact, source-party assertion, calculation, and reviewer interpretation; preserve dates, units, comparisons, status, and uncertainty. Identify missing context rather than filling it from memory. Derive document family, subject type, decision context, and permitted conclusions only from the supplied inputs and profiles. Treat empty optional values as absent and return only the requested result. Your response must conform exactly to this output schema: {schema_json_string}.
