The 7 and the 49.5 are medians over 48 recorded bench runs. \n\nRouting was off in those runs, so each model call counts as one decision a router could make. Pooled over the runs, System One decisions are 17.0% of calls (419 of 2,467). The policy is the third scenario: it decides every call in process at no model cost.","sourceIds":["calc-routing-at-scale","agent-routing-overhead","agent-routing","price-anthropic","price-jev"]}}
