{"method":["This is a calculation, not a run. We made no new model call and ran nothing at scale. Every input is a number from a recorded run in this dataset. The volumes (10,000, 100,000, 1 million, 10 million decisions a day) are parameters, not measurements.","Jev cost per 1,000 is a calculation from the routing study’s provider-reported total cost and counted calls. Claude cost comes from its token totals and list prices, with one-hour cache writes. Jev costs $0.0337 per 1,000, a calculation from the reported production run cost (n = 82). \n\nSonnet 5.5 at effort low and Haiku 4.5 ran through the Claude Code CLI. Their cost is list price × the tokens the CLI reported (Sonnet n = 82, Haiku n = 82). The policy makes no model call, so it costs $0. The live Jev run gives $0.0337 per 1,000, a calculation from reported input tokens and the published price. The two figures agree at this precision.","Claude median and p95 times come from the routing receipts; we checked them against the per-call rows. The overhead summary uses different quantiles for those calls, so we do not mix its median or p95 into this calculation. Run ranges and policy times come from the overhead results. The policy is the production routing decision, timed in process over 20,000 decisions (median 1.42 µs, 95th percentile 2.33 µs, maximum 2538.21 µs; minimum unavailable). \n\nSonnet 5.5 and Haiku 4.5 are wall time per call through the CLI, one call at a time, from the recorded routing runs (Sonnet n = 82, Haiku n = 82). Jev is the live run: 246 calls (82 typed decisions × 3 repetitions) over direct HTTPS from one Mac, one call at a time, as client wall time.","Daily cost = decisions a day × cost per decision. Decisions per second = decisions a day ÷ 86,400. Decisions in flight = decisions per second × time per decision in seconds (median/p95 scenarios; Little’s law requires the mean). The median time gives the bar. The 95th percentile time gives the whisker. \n\nWaiting hours a day = decisions a day × time per decision ÷ 3,600, if each request waits for its decision. Cost per year = cost per day × 365.","The scenarios use 1,000,000 model calls a day. In the first, a router decides every call. In the second, it decides only the System One decisions: 7 ÷ 49.5 = 14.1% of calls. That ratio uses the medians of 48 recorded bench runs. \n\nRouting was off in those runs, so each model call counts as one decision a router could make. In the third, the policy decides every call in process.","Policy capacity is the measured 469,409 decisions per second in one process, set against the rate each volume needs. The measurement leaves out the database reads and the decision-record write of the production decision."]}
