Breaking: Browser Use + Jev = Ultrafast Findings flights

Built a browser agent where Jev picks actions from the DOM state space each step, booking flights in 7 seconds for $0.0039.

Breaking: Browser Use + Jev = Ultrafast ⚡

Findings flights took 7s and cost only $0.0039 🤯

> new action space every step

> DOM state space

> small LLM fallback to type

• @SUOHA_AI — Browser Use 接上 JEV 这速度太他妈吓人了吧？？ 过去大家看 GPT、Claude 操控浏览器，体验其实并不好，因为真的太慢了，中间还经常卡死... 因为让大模型写一堆长篇大论去操作网页，本质上就是杀鸡用牛刀 在网页上点按钮，本质上就是一个离散的多选题，根本不需要 AI 会写诗 JEV 拿到 DOM 结构，以做分类题的速度毫秒级选出该点的元素，只有在需要打字输入时才偶尔回退给小模型
• @AYi_AInotes — 喵的，开源社区有点过于凶猛了！！！ 拥有 4.5 万星的 Browser Use 创始人 Gregor Zunic 刚刚发了段实测视频， 直接把整个浏览器自动化（Browser Agent）行业的桌子给掀飞了： 查一次真实的航班机票，从打开网页、输入筛选到返回结果， 全程只花了 7 秒钟！单次成本只要 0.0039 美元（折合人民币不到 3 分钱）！
• @NFT_Chen — 🤯难以置信！Jev × Browser Use把浏览器速度打到变态快！ 实测案例：给一句目标「苏黎世→伦敦，9月20日单程经济舱」，Agent 自己打开 Google Flights，切单程、填城市、选日期、点搜索。全程 1 倍速，含打字和页面加载。 亮眼表现： 🔹7.1 秒出结果 🔹成本仅 $0.0039 🔹协议调用 1092 → 101，砍 91% 🔹中位耗时再降 25% 🔹决策约
• @jurlycat — Jev is what happens when you stop forcing AI to talk. ​ It’s the first public “System One” model from TypeSafe AI, built for fast decisions inside software—not conversations. ​ You give it: ​ •
• @opc0de3 — two days ago a guy shipped a model that cannot write text. yesterday someone plugged it into a browser and searched flights for four tenths of a cent $0.0039 per task. seven seconds. and the video is
