Jev 成本对比与 20 个高 ROI 决策场景
称 Jev 做 1000 次决策约 0.4 美元，远低于前沿 LLM，并列出工单路由、退款审核、模型路由、工具调用重试等 20 个适合 Jev 的高频决策任务。
Use cases where Jev is significantly more cost-effective than general frontier LLMs: Making 1,000 AI decisions with Jev costs around ₩500 (~$0.40), whereas frontier LLM models can easily cost tens of thousands of Won. Tasks that satisfy all three conditions are ideal for Jev (otherwise, a standard LLM is better): 1. High volume / high traffic 2. Consistent decision criteria every time 3. High time-sensitivity (momentary delays lead to losing customers) 20 High-ROI Use Cases: 1. Route new incoming inquiries to the right team. 2. Score the urgency of an incoming inquiry. 3. Decide whether to approve, reject, or flag a refund request for human review. 4. Qualify new leads: target customer check vs. immediate buying intent. 5. Filter inbox emails that require a reply today. 6. Pick 5 useful items out of 100 search results. 7. Verify whether supporting evidence actually backs a claim. 8. Retain only relevant context from past conversation logs. 9. Score thousands of table rows at once based on a few criteria. 10. Map receipts/proofs to the correct accounting categories. 11. Measure how far a contract clause deviates from standard boilerplate wording. 12. Score and re-match optimal suppliers for each request. 13. Direct incoming tasks to the appropriate model (model routing). 14. Decide to retry or wait when a tool call fails. 15. Judge if a task is complete or needs another step. 16. Quickly score whether a large model's output followed instructions. 17. Check if an action is reversible to decide between auto-retry and human review. 18. Escalate to humans only when confidence is low, cost is high, or action is irreversible. 19. Detect redundant or repeated steps in execution logs. 20. Validate compliance with company rules rather than grammar. At the operational level, you need to apply optimal metrics that derive actual value from these output probabilities.
