# TypeSafe AI发布Jev：一种叫"System One"的新型LLM，专注做决策

TypeSafe AI 上周发布 Jev，称其为一种全新类别的模型，命名为 System One 模型，也有人更愿意叫它决策模型。Jev 仍是文本输入，但在模型格式上做了改动，目标不是通用生成，而是决策类任务。这一方向若成立，可能为 LLM 在需要快速判断的场景中提供比推理模型更合适的选项。

## English Version

**TypeSafe AI Unveils Jev, a 'System One' LLM Built for Decision-Making**

TypeSafe AI last week unveiled Jev, describing it as a new category it calls System One models, or decision models. Jev still accepts text inputs but alters the usual LLM format, targeting decision-making tasks rather than general generation. If the approach holds up, it could offer a better fit than reasoning models for scenarios requiring fast judgment.
