What exactly is Jev?
Explained that Jev takes material plus predefined questions and returns structured answers only, unlike chat models that write text.
The original post, translated
What exactly is Jev? Jev all over the screen is an AI specifically made for software to "judge." Ordinary large models (like ChatGPT, Claude) are for writing things: you ask a question, and it spits out sentences one word at a time. Jev is the opposite: you give it a piece of material (such as a customer service email, a work order, a section of logs), then give it a few pre-set questions, and it only returns structured answers, without writing any words.

到底什么是 Jev ？满屏的 Jev 它是专门给软件做 “判断” 的AI。 普通大模型（ChatGPT、Claude这类）是写东西的： 你问一句，它一个字一个字往外吐句子。 Jev反过来： 你给它一段材料（比如一封客服邮件、一个工单、一段日志），再给它几个事先定好的问题，它只返回结构化答案，不写任何话。

Where this case fits
Filed under general Jev builds. 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. Browse the full case library for the work it sits next to.
