I built a Jev plugin for @raycast. Now you can ask questions directly to Jev by simply hitting ⌥ + <space> Checkout the video to see it in action. https://t.co/qWAElRjz4K

试着vc了第一个基于jev的插件。 Jev Tweet Radar，Chrome扩展，刷X时根据jev给的概率分析，高效的判断是否值得互动。 可以根据目的，自行定义自己想互动的类型。 中日英三语，MIT开源 刷1小时不到5毛，效果如图 https://t.co/qhyMFSE2EG #Jev #TypeSafe https://t.co/ZHxXyMxM6t

I implemented Jev @typesafeai to auto attribute categories to expenses on an open source app I’m building. https://t.co/yudLXwgSln

試しに browser-use/jev-ultrafastを使ってみる 東京駅から車で3時間以内で、明日から1泊2日で5万円以下で泊まれる宿を楽天トラベルで探してみたところ、時間は13分の1、コストは190分の1に https://t.co/wCqasGNOuB https://t.co/k5aDtw7Kiq

I built dre as a keyboard-first diagram editor. Turns out that's also what makes it easy for AI to drive. In this demo, plain-English sentences build the diagram. Jev (@TypeSafe) makes each decision in ~0.6s and the app presses the keys. The catch: Jev can't generate text. It only picks from typed choices. So every decision is a choice: → which command? (child, sibling, parent, color…) → which wor

No more accidental spoilers! Got access to @typesafeai Jev and as a test made myself a Chrome extension that hides spoilers in real time, for any website. It scans the DOM looking for anything revealing and obscures it instantly. Text, images, even the YouTube timer and progress bar. Such a cool model, so many use cases!

@typesafeai Jev powering near real time full duplex voice agent with cascaded architecture. Here's the pipeline: mic → @DeepgramAI Flux (turn detection) → @typesafeai Jev → @GroqLLC GPT-OSS-120B LLM → @SarvamAI TTS → speaker, with a live @excalidraw canvas on the side. https://t.co/0jZdiWZDAt

Got Jev AI playing Minecraft, and I genuinely didn’t expect it to move this fast. In ~80 seconds it chopped wood, crafted tools, mined cobblestone and got the stone pickaxe upgrade. It still made some very AI mistakes though, It mined cobblestone, used it to get itself back out, then later had to go down for more. Built the setup with Astra’s help. Really cool seeing this actually work.

does jev understand canada? here’s a demo where jev predicts the areas of canada that match with a given word it responds instantly and cost me less than a penny https://t.co/605JA3opRz

We turned Jev into a general browser skill for agents: jev-browser. Give it a website and a task. The browser opens automatically, and Jev decides every click based on what's on the screen. Here's a demo: https://t.co/mhlknQtDTk

@typesafeai JEV plays TETRIS. Not too bad but not like a world champion yet. For every new piece, I made it pick the best placement among all the possibilities given to it by a custom-built TETRIS version. And it made decisions in less than 400ms on average. And cost is insanely low. Quite impressive.

Built Jev for X as a small Chrome extension. 🚀 It adds a live semantic layer directly on top of X: 🧠 Timeline posts get categorized 💬 Replies can be filtered in the context of the original post 🧩 Different conversations use different reply labels For example, an opinion thread might use: Agree · Disagree · Counterargument · Question While a product launch might use: Feature Request · Pricing Conce

i made Jev (@typesafeai) play clash royale. Qwen 3.8 27B on @cerebras reads the battlefield, OpenCV reads cards + elixir, and Jev picks the card + placement. fresh account, starter deck. it won multiple games against REAL people. i'd be so annoyed https://t.co/wPhFh6bYNn

Jevのレスポンスの速さを活かして、テキスト入力中に自動で絵文字を差し込むテキストエディタを作った。 入力中のテキストを随時送信。1,000種の絵文字から一致するものを判定してエディタに差し込む仕組み https://t.co/1XuymyUmqy

用JEV做简历筛选这个案例确实有趣且实用，我自己一vibe 了这个实验。500份面试，每份纪要都让 Jev 分别回答 6 个问题，一共3000次判断，用时 31.4 秒，估算 $0.03173 一次请求详细字段见评论 https://t.co/mblXTmbska

Can you beat JEV at pong? defend your wall, add some traps and see how fast JEV can react . Try to beat it here : https://t.co/S4P1jVuK3d Each decision consume my credits, so JEV won't work if i'm out of credits wondering how long that will last. Going to sleep now. https://t.co/s0Z4oNzCVH

I’ve been experimenting with Jev from @typesafeai , and wanted to see what happens when you give it a live chess game. So I built a system where a Chrome extension captures the board state and move history, sends it to a local backend, and feeds the data into Jev. Jev predicts the next move, and I manually play it on the board. No Stockfish. Just Jev making the decisions. Here’s a 1-minute look at

天気マップにJevで"お出かけ判断"をつけた。 自由文で「◯◯したい」と入れると、天気を見て向き/不向きを判定。 単純な閾値はコードのまま、"意図×天気の常識判断"だけJevに任せる役割分担にした。 #Jev #TypeSafeAI https://t.co/DBfLFEwrEu

Jev can serve as better natural language search on websites. It can scan thousands of Zillow listings and classify properties by things you can't normally filter for - e.g. architecture, renovation status, proximity to freeways. This was done in <20 sec and costs $0.18 👇 https://t.co/qPCeVzI850

I used Jev, TypeSafe's new AI that doesn't write a single word It works best paired with Claude Opus. I tried that on my own article Opus prepared all the prompts and questions, and Jev scored the article on 17 key questions at once. All 17 answers came back in under half a second, and six checks cost me a fraction of a cent. Jev is a good analyst, it found the weak spots in my article and shows a

Built a Chrome extension that tells you how well your resume matches a job posting! Powered by TypeSafe Jev. Open source and BYOK. Works with both direct typesafe key or Vercel gateway key! https://t.co/SaXADjYbZC

実際動いてる時のゲーム画面（これも4倍速） 日本だと400-500msでしかJevが反応しないので、500msを1ターンとし、それを100msで動いた時の感触を見れるようにしている https://t.co/bgDqGjS4cc

箱庭諸島をJevが操作するゲーム作った！ 1ターンが500msとかになっているので本家箱庭諸島では味わえないRTSみたいになっている🔥 遊んだあとは遊んだ結果をmp4で出力可能！是非遊んでみてね https://t.co/tfDVjJfpIw https://t.co/6daoHMDnIP

刚才突然想到一件事：前端要是不让模型写代码，只让它做选择，会不会快很多。然后就拿同一份需求试了一下。Jev 不写代码，只做决策，界面直接用自己的组件库拼出来。 0.7 秒，页面已经能点了。同一份东西丢给 DeepSeek V4.1 Flash，它还在老老实实写 HTML，84 秒。前端前期我要的其实就这三步：先出原型，马上改，改完立刻测。 不是先把整站写完。生成还在写。 决策已经能点了。

i built an AI that scores dating profiles for "NPC energy" — paste a screenshot, get a score, the clichés, the red flags and the green flags. no signup. nothing stored — it reads your screenshot and forgets it instantly. powered by Jev , @typesafeai link below try it ⬇️ https://t.co/Yhg9FzTbvm

Saturday what a geek does? try the new AI kid in the block Jev by @typesafeai so took 1000 jobs sample from one niche job board listed on JobBoardSearch it tags each one seniority full time or contract remote / hybrid / onsite category then the useful part is this a real job or spam or expired or a recruiter posting and if the description is actually usable title employer location requirements sal

I created a @googlechrome extension that uses @typesafeai Jev to filter @Twitch live stream chats in real time. 2 messages per second = <$0.15 per hour 50 messages per second = <$0.76 per hour https://t.co/RzgQphJrGW

I made Jev play chess against me. How did I do it? Jev can't generate a move. It's a classification model, so it only picks from options you hand it. That turns out to be easy to work around. Any position has a fixed set of legal moves, so I generate all of them in code and let Jev choose one. Then I built a small app with a basic UI and played it. First I wanted a number, so I ran it against 600

@GitHubNext Would be interested to hear how it stacks up? See https://t.co/2c2k0er2NK where I benchmarked Jev vs other models. Context is I used this to use it for realtime decision making to visualise the impact Jev has for these types of use cases. It's fat and still pretty intelligent https://t.co/J1zj0KDfmA

What if an AI that can barely do anything is exactly what makes it 200x faster? That’s JEV. It makes simple decisions in a fraction of a second and can reportedly be 40–400x cheaper. I built 10 of them. Comment “Agent OS” for the guide. https://t.co/a9SMgTRw6T

Spent a little while with Jev, a model which doesn't output the next tokens but it returns typed answers and probabilities your code can use directly. So what did I do? I asked claude for ideas on what to do with Jev. So it built "jgrep": grep where the pattern is a description instead of a regex. Asked both tools for network calls with no timeout. Regex returned 5 hits, 2 of them wrong — it can o
