Jev入门:用TypeSafe AI做结构化决策与低成本自动化

Jev for beginners: how to use it and what to build

原文
发到 X

Jev is TypeSafe AI’s new decision model. It returns type-safe structured values (a choice, a score, a probability) instead of generated text, at 4 cents per million input tokens with no output charge. This week I ran it on five real projects: PR categorization, a meta-analysis of my own Claude and Codex sessions, Gmail triage, the ChatPRD product insights graph, and a live audience dashboard built from 4,500 YouTube comments.

Jev 是 TypeSafe AI 推出的全新决策模型。它返回类型安全的结构化值(如选项、评分或概率),而非生成的文本,每百万输入 token 仅需 4 美分,且无输出费用。本周我在五个真实项目中对其进行了测试:PR 分类、对我自身 Claude 和 Codex 会话的元分析、Gmail 邮件分拣、ChatPRD 产品洞察图谱,以及基于 4,500 条 YouTube 评论构建的实时观众仪表盘。

What you’ll learn:

你将了解到:

  • What makes Jev fundamentally different from every other model I’ve used
  • How I analyzed 1,700 PRs for 9 cents and what I found out about where my engineering effort actually went
  • The personal meta-analysis you can run on your own Claude and Codex sessions right now
  • Why I stopped using Jev alone, and what I pair it with now
  • How I turned 4,500 YouTube comments into a searchable audience dashboard for almost nothing
  • The real-time app I built in an afternoon that shows something surprising about Jev’s speed
  • Why Jev’s pricing model is different from any LLM I’ve used, and what it makes practical to build
  • The ChatPRD product insights project: 1,100 signals, 200,000 classifications, and what it cost me
  • 是什么让 Jev 与我使用过的所有其他模型从根本上不同
  • 我是如何以 9 美分的成本分析了 1,700 个 PR,以及我从中发现我的工程精力实际流向何处
  • 你可以立即在自己本地的 Claude 和 Codex 会话上运行的个人元分析方法
  • 为什么我不再单独使用 Jev,以及我现在将其与什么搭配使用
  • 我是如何几乎零成本地将 4,500 条 YouTube 评论转化为可搜索的观众仪表盘的
  • 我在一个下午构建的实时应用,展示了关于 Jev 速度的惊人事实
  • 为什么 Jev 的定价模式与我使用过的任何 LLM 都不同,以及它使得哪些构建变得切实可行
  • ChatPRD 产品洞察项目:1,100 个信号、200,000 次分类及其成本
