Recently there is an AI model called Jev, the price is a bit absurdly low: 0.042 dollars per million input tokens, that is, 1 billion tokens, 42 dollars. And output is not charged because it has no output tokens at all. This model cannot write articles, cannot write code, and cannot chat nonsense. It cannot even generate text. This model can be called "a large model that only does multiple-choice questions".

最近有一个叫 Jev 的 AI 模型，价格有点夸张的低 每百万 input token 0.042 美元，也就是 10 亿 token，42 美元 而且 output 不收费 因为它根本没有 output token 这个模型不会写文章，不会写代码，也不会瞎比聊天 它甚至不能生成文字 这个模型可以叫做“只做选择题的大模型”

Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.
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.
