Jev 是 Typesafe AI 推出的“系统一”模型，现已在 OpenRouter 上线 Beta 版。它不生成文本，而是基于应用状态和类型化问题，直接返回带概率的类型化决策。
RT @alexatallah: Jev is a model that efficiently makes */decisions* This is a huge devex win for AI. As a team that believes in ruthless type checking, being able to expand this love to our classifiers and decision making processes means 100x more AI usage. The quintessential Jevons paradox model
Jev by @typesafeai is now on OpenRouter, in beta. Jev is a System One model. Instead of generating text, it takes your app's state plus a typed question and returns a typed decision with a probability attached. There is no JSON prompting, parsing layer, and nothing to validate against.
