Jev 让「给软件做决策的模型」这一区分变清晰
作者认为 Jev 代表一类新模型：不聊天不写码，只接收状态和允许的决策集，返回带概率的类型化答案，适合路由、过滤、打分、审核等场景。
I think AI is about to split into two very different kinds of model. Models that talk to humans, and models that make decisions for software. Jev is the first thing I’ve seen that made that distinction really click for me. It doesn’t chat and it doesn’t write code. You give it some state and a set of allowed decisions. It returns typed answers and probabilities that your program can act on directly. Sounds less impressive than a giant reasoning model until you think about how much software is basically "given this messy situation, which of these five things should happen next?" Routing, filtering, scoring, moderation, fraud checks, tool selection, escalation, workflow decisions etc etc We’ve been using models built to talk to people for jobs where nobody actually needed them to talk.
