Jev System One 模型适合需要稳定结构化决策的 AI Agent 系统。下面是常见生产用例，以及给开发者的实践笔记。架构背景可参考 Jev 与传统 LLM 对比。
AI Agent 路由
用 Jev 对用户请求分类，并送到对应的专业 Agent。
开发者提示：可减轻主 LLM 的 prompt 工程负担，并减少因自由文本输出不稳定导致的路由错误。
内容审核打分
对用户生成内容分类，并输出结构化风险分数。
开发者提示：适合高吞吐审核流水线，需要一致、可复现的评分规则。
欺诈信号与 KYB 复核
用 Jev 判断应用已收集证据中的具体风险信号。
开发者提示：风控策略、授权和人工复核由应用负责。
多 Agent 系统中的任务分类
在进入下游处理前先对任务分类。
开发者提示：把分类结果写成工作流日志中的明确事件，便于重试保持幂等。
什么时候不要用 Jev
- 长文写作、创意内容
- 开放式聊天或客服对话
- 复杂多步推理
