Jev cost calculator
Enter how many decisions you make per day and how big each input is. The table shows the monthly bill on Jev and on popular LLMs at list price. With an LLM, you also pay for the output tokens it generates (the label, plus any reasoning). Jev doesn't charge for output.

List prices at standard tier, verified Sep 18, 2026 from each vendor's pricing page. Jev bills input tokens only. A month is 30 days. Token counts differ between tokenizers, and discounts such as prompt caching or batch processing are not included, so treat this as an estimate. It compares price only, not accuracy: whether Jev is accurate enough for your task is something to measure on your own data.
How to read the result
Price is only half of the comparison. An LLM can reason, explain itself, and handle open-ended tasks that Jev can't. Jev is built for one thing: fast, typed answers to well-scoped questions. The fair comparison is on the decisions where both are good enough, which you need to measure on your own data.
See Jev pricing explained for how billing works, and What is Jev?for the kinds of questions it is and isn't good at.
