"questions":{"topic":{"type":"choice",
"instructions":"Route this message",
"criteria":{"billing":"money","bug":"broken","account":"login"}}}}'What that actually means
At $0.42 per million input tokens, Jev is one to two orders of magnitude cheaper than calling a frontier LLM for the same classify/route/score task — and it returns a typed answer instead of text you'd have to parse. TypeSafe estimates an average decision costs about $0.0004 on their benchmarks.
- 1,000 decisions ≈ $0.40
- 1 million decisions ≈ $400
- Output tokens are free, so batching several questions into one call is cheap.
Per-decision figures are estimates from published benchmarks; your real cost depends on how large your state is, since you pay per input token.
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.
