Jev: reported input tokens × $0.042 per million, output free. Claude: CLI-reported tokens × list price; the CLI wrote its prompt cache as 1-hour writes, priced at 2× input, and adds its own system prompt and tool-schema tokens. The Claude routers ran on a subscription. At the tuned-set study’s convention (every cache write at 1.25× input), Sonnet 5.5 (low) would be $4.877 here. That study shows $4.996 for it on its own cases, where the CLI reported $7.324, so its cost row and this one differ by convention and by case mix.","sourceIds":["agent-routing-holdout","calc-repricing","price-jev","price-anthropic"]}}
