Jev and OpenAI's Decisions API launch the same day: decision models as a new track
The article frames Jev as a model that only makes typed decisions, compares it with OpenAI's same-day always-on agents and Decisions API, and argues AI is splitting into coworkers and smart if-statements.
What this article says
文章以 2026 年 9 月 30 日为观察点，指出 OpenAI 在同一天发布了两类产品：一类是常驻、自带电脑的 agent（dots），另一类是 Decisions API。与此同时，TypeSafe 发布了 Jev——一个只负责做类型化决策的模型。作者的核心判断是：AI 产品正在分裂成两个方向，一边是能当同事用的通用 agent，一边是「智能 if 语句」式的轻量决策组件。Jev 属于后者：输入一个问题、一组固定候选答案和上下文，输出一个代码可以直接分支的选项。文章还顺带提到 ClickHouse 合并与 AGENTS.md 等同期动态，但主线是这条决策模型赛道的形成，以及它和通用 agent 路线的分工。
OpenAI launched dots, always-on agents with their own computer, and a Decisions API on the same day. TypeSafe launched Jev, a model that only makes typed decisions. AI is splitting into coworkers and smart if-statements. Plus ClickHouse merges, AGENTS.md. https://x.com/i/article/2105307999958876160
