Jev vs Claude Opus 5: cost per decision
Opus is a poor fit for high-volume classification on price alone, so the interesting question is not which is cheaper but how much of your Opus spend is actually doing Opus-grade work.
| Scenario | Jev 1.13 | Claude Opus 5 | Ratio |
|---|---|---|---|
Light 10k items/day, 300-token state, 2 questions | $5.29 | $855.00 | 162x |
Production 100k items/day, 500-token state, 4 questions | $93.24 | $14,850 | 159x |
High volume 2M items/day, 300-token state, 1 question | $856.80 | $117,000 | 137x |
Monthly, 30 days. Both sides answer all questions for an item in a single call. Claude Opus 5 additionally pays for its output tokens at $25/M; Jev 1.13 has no output charge. List prices at standard tier, excluding caching and batch discounts.
Where Claude Opus 5 still wins
Opus is worth its rate on multi-step reasoning, synthesis and writing. None of that is a typed decision, and Jev cannot do any of it.
The honest caveat
This compares price, not accuracy. A model that is 100x cheaper and wrong 5% more often can easily be the more expensive choice once you price the mistakes. Jev returns a calibrated probability with every answer, so the practical move is to route the confident cases automatically and send the rest to Claude Opus 5 or a human — which makes this a routing decision rather than a replacement decision.
