Jev is priced for high-volume use: you pay only for input — from $0.42 per million tokens, dropping to $0.25/M on larger prepaid packs — and output is free. For the same classify/route/score task that makes it one to two orders of magnitude cheaper than a frontier LLM, and it returns a typed answer instead of text you'd have to parse.
- Prepaid packs from $5 — credits never expire
- Input from $0.42/M, dropping to $0.25/M on larger packs — output free
- Each decision costs a fraction of a cent — batch questions into one call to save more
You pay per input token, so your real cost scales with how large your state is — batch questions into one call to share it.
Rate limits
- 250,000 tokens / second
- 1,200 requests / minute
How to lower your bill
- Trim the state. You pay per input token — send only the context the decision needs.
- Batch questions. Several questions share one state payload in a single round trip.
- Route by confidence. Let Jev auto-handle the easy, high-confidence cases and reserve expensive LLM calls or human review for the uncertain few.
