What counts as input
State and question text contribute to input. More context and longer rubrics can increase cost. Jev ingests shared state once and evaluates questions against it, so one request with independent questions can avoid repeating the largest part of your input.
The exact account usage returned by the provider is authoritative. Your character count, approximate tokenizer, or calculator can differ because serialization and accounting details matter.
Example cost calculations
For a request with an estimated 1,000 input tokens, cost is 1,000 / 1,000,000 × $0.042. A million requests of that size is a billion estimated input tokens.
For monthly planning, multiply average tokens per request by requests per day and days per month. Include expected retries and failed-request accounting according to your provider. Do not include output charges for the direct API when output is free.
Several questions, one state
Suppose the state is 700 tokens and each of three questions is approximately 120 tokens. The planning estimate is 1,060 tokens per request. Three separate requests would repeat the 700-token state three times. Batch only independent questions; when a later question requires an earlier answer, that dependency may justify another request.
State size and cost
Trimming irrelevant content can improve both the estimate and the quality of the judgment. Avoid aggressive trimming that removes evidence. Compare a short and long state against labeled examples rather than optimizing cost in isolation.
Direct vs provider pricing
Provider gateway fees, model prices, quotas, and token accounting may differ. The calculator supports a custom per-million-input rate so you can enter a price from your provider. It does not fetch live prices or claim to model unrelated gateway charges.
Estimate monthly cost
Open the cost calculator, enter your average state and question sizes, and compare the result with observed usage.input_tokens. Revisit the assumptions when you add a rubric, language, or longer retrieval context.
