UI Spec approach splits UI generation into LLM, Jev decisions, and a renderer

The approach breaks UI generation into three steps: an LLM understands the request, Jev picks components and layout from a limited set of candidates, and a renderer draws the interface deterministically.

这将改变UI的形式,UI Spec 传统 LLM: 用户需求 → LLM 生成 UI JSON → Renderer → UI 问题在于 LLM 同时承担了「决策 + 生成」 Jev: 用户需求 → LLM 理解需求 → Jev 做决策 → UI Spec → Renderer → UI (1)LLM:理解需求,探索“应该做什么” (2)Jev:从有限候选空间里决定“选哪个、怎么组合、怎么排列” Jev决定 组件:Button text:Buy now position:右下角 action:checkout (3)Renderer:按照 UI Spec 确定性地把界面渲染出来 Renderer 接收到这个 Spec 后,负责: UI Spec ↓ Renderer ↓ React / HTML / CSS ↓ 真正的 UI Jev 把 UI generation 从“自由生成问题”变成“有限决策问题”
