Cost calculator FAQ
- Is this a separate product from the token calculator?
- Same engine, cost first. This view keeps the spend projector and drops the per token visualiser. Tokenizer flips that around, and Home shows both.
- How do I estimate monthly spend?
- Set output tokens, optional cache hit % and Batch, then enter users and messages per day. The panel projects daily, monthly, and yearly cost.
- Are prices live?
- Rates are curated from official provider pages and stamped with a last-verified date on each model. Always confirm critical budgets on the provider’s pricing page.
