Why has it suddenly become popular recently?
Explained that Jev does not chat or write code but only makes decisions, arguing it targets the waste of using large models for simple judgments.

What is Jev? Why has it suddenly become popular recently? It doesn't chat, doesn't write code, and doesn't even generate text; it is responsible for only one thing: making decisions. This seems like a small thing, but it may have hit the biggest waste of Agents: Have we been using the most expensive large models to make the simplest judgments?

Jev 是什么？为什么最近突然火了？ 它不聊天、不写代码，甚至不生成文本，只负责一件事：做决定。 这件事看起来很小，却可能击中了 Agent 最大的浪费： 我们是不是一直在用最贵的大模型，做最简单的判断？

Where this case fits
Filed under agents & workflows. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the agents & workflows page.
