Jev 是什么：把 AI 当多选题而非写作文
作者用 ELI5 解释 Jev：不做聊天，只做软件能直接执行的判断（是否垃圾、agent 该调哪个工具、要不要转人工），并称在 TypeSafe 自家工作流基准上比前沿 LLM 快约 200 倍、便宜约 400 倍。
WTF is Jev by @typesafeai? Here’s the tl;dr ELI5: Think AI multiple choice, not AI essay writing. It doesn’t chat. It makes decisions your software can act on: “Spam or not?” “Which tool should this agent use?” “Does this need a human?” The exciting part: roughly 200x faster and 400x cheaper than frontier LLMs in TypeSafe’s own workflow benchmarks, with responses in a fraction of a second. Why that’s powerful: imagine an app or agent making hundreds of little judgment calls without hundreds of expensive, slow conversations with an LLM. Keep the big model for the hard thinking and writing. Use Jev for the rapid-fire decisions in between. Excited to dig in.
