Built a music intelligence platform with Jev. 3,274 songs. 114 genres. Measured “Soul” vs “Subversion.” And the entire audit cost me ~$0.0001. That’s the part that blew my mind. Subjective intelligence at massive scale, for basically nothing. #Jev #AI #MusicTech

I just created Jevmind 🧠 Watching AI agents make decisions drove me crazy. They write a whole paragraph, then guess what it meant. No idea how sure they are no memory of being wrong. So I built a brain for them: → every choice becomes a clear answer with a confidence score

I built an open source voice control plugin for @OmarchyLinux using Whisper and Jev from @typesafeai. Its called Voicebind. I love keybindings in Omarchy and use voice control as a second option. Its nice to have both. @dhh 🙏 You can use a phrase to enable listening

not every task needs the same model built Auto Jev-Codex for Paseo to pick the right setup for each turn open source

Releasing Jev Desktop as open source. This is about 10x faster that GPT-6-Astra's native computer use in limited testing. This will be maintained as it's planned to become a core part of my internal verification workflow. https://t.co/9rFzo3HFnc

To test out Jev's accuracy and speed i looked to solve something my wife dreads, grocery shopping. So I built an auto shopper that uses both @OpenAI luna model combined with @typesafeai jev that creates grocery lists and automatically fills the online shopping cart for Giant Food

I built a tool powered by Jev that extracts any products features and business logic into a markdown repo Enter a product URL and you can copy features, ICP, messaging, pricing strategy, etc straight to a md file

I gave JEV at every AI paper since 1993

My time with a US-based remote startup recently came to an end. So I made every YC company interview my resume. Jev read it against all 6,245 YC companies in 25 seconds. Cost: $0.37. 156 founders should take my call. The list, the workflow, and the tool 🧵

@rishavkatoch

hopping on the jev bandwagon. built a tiny project to declutter my internet life: TabJev 🗂️ Open a tab → it figures out if it’s Work, Dev, Social, etc. → puts it in the right group. Use the defaults or create your own groups. Free. Open source. Bring your own key.

@SinghDevHub

I built a tiny AI civilization using @typesafeai 's Jev + @DevinAI + GPT. 48 citizens share an island. Each has a role, skills, hunger, energy, health, and memories: • Farmers produce food. • Builders gather resources and construct buildings. • Nurses treat injured

I built a @Polymarket trading agent using @typesafeai's new model, Jev. Here is an example of it placing a profitable prediction on the 5 minute BTC UP/DOWN market. The code is open source: https://t.co/pR1HMEd9qE

Context compaction shouldn't eat the error you're trying to fix I built fast-jev-codex: Jev scores tool history, then the plugin restores verbatim context after Codex compacts. Open source. Bring your own Jev key.

Chris Nicholas

@ctnicholasdev

I've built an open-source workflow builder for Jev! Experiment using a UI—classify inputs using choices, scores, booleans; wire results into other prompts; and return a set of custom outputs. Below I've set up a support system that can help with various queries. Features ↓

Ruban

@RubanBhatia

I keep defaulting to the strongest model and highest effort just to play it safe. So I made Switchboard to choose for me in Codex and Claude Code. It’s open source and powered by @typesafeai Jev (but support for other System One models coming soon). Give it a try and tell me

Chen

@xinyao27

Jev doesn’t write code. I use it to decide which model should. I built Jevonian, an open-source local router for coding agents. Keep your agent. Jev picks the model and thinking effort for each turn. See what ran, why it was picked, and its estimated cost. Built with

@_koushikde_

jev just solved agent security, and it's fast. i built jev-firewall — a firewall that sits between your coding agent and your computer. every tool call gets judged before it touches your machine. >no agent deciding what the agent is allowed to do. >rules kill the known-bad in

I built Inbox triage using Jev 🤯 So I point my gmail to jev and it classifies all the emails i have in my inbox and put them in specific category folder. It was built using claude. I also published a small demo video on my youtube. Sharing the repo and youtube link below.

@0xwhrrari

Jev + GrokBot is the best AI agent system I've built for my Mac It just analyzed 12 live options, ranked them in 0.18 sec, and stopped before the irreversible action - for ~$0.0000021 setup takes literally 7 minutes: prompt → GrokBot → Jev decision → GrokBot execution →

@djrio_vr

Jevのテストとして、とりあえずXで自分が見たくないなぁって投稿を判定して非表示にするChrome拡張機能を作ってみました。 リアルタイムに投稿内容を判定しているけど、めちゃくちゃ速い＆安いです。ベンリ！ github: https://t.co/E6oG8wyRS5

void

@sakevoid

i built a safety hook that screens every shell command before claude code is allowed to run it. the idea is simple: before execution, jev looks at the command and answers one question: "should this command be stopped?" then deterministic code decides what happens next. low

Debarpan Jha

@DebarpanJha

Jev is INSANE. I built a LinkedIn Post Copilot to score posts, explain the results, and suggest improvements using structured analysis. No API key? It scores offline using a deterministic local heuristic. https://t.co/ys32qPwDaZ #Jev #AI #Buildinpublic @typesafeai

@pranavbarthwal_

unlocked a new jev usecase today a publisher, secretly, ran our ad tag on their 🌽 sites none mapped on our dashboard now jev will check at runtime > tag loaded on a related domain / subdomain / mapped domain? allow. > phishy corn site? blocked.

@luongnv89

So instead of chasing which posts I should pay attention to, I am using Jev (combine with my original Algo) to have this floating panel Now I can quickly find which posts are most relate to my interest, and probably save ton of time because of dump scrolling, but hey, dump

I turned Jev into a Flappy Bird player and I won against it (sorraay @typesafeai). Can you beat it? Let's see your score: https://t.co/ktQrUYvPHb Tech: - Results stored in @neondatabase Postgres - @nextjs App Router 16 with @DrizzleORM, @shadcn and @tailwindcss - pdx1 region

@rishi_raj_jain_

Had Jev (@typesafeai) read every comment on the most-discussed threads on Hacker News (@hackernews) and give a verdict ⚖️ → https://t.co/WzAWif9Ekj • Every comment judged by Jev: stance (support / critical / neutral), a substance score, a 0..1 quotability, and whether it

Built content-aware PII redaction in Postgres with @neondatabase and @typesafeai's Jev where redaction on support messages is not on entire column bluntly, but only on meaningful bits: https://t.co/sOSG4tXCot 🎉 • Jev reads each message and tags the personal bits: names,

Launching FyleContext. 1/5 Upload PDFs, docs and URLs once. Claude (or any MCP client) searches them and cites the exact page. TypeSafe Jev scores every passage before it reaches your model. Nothing relevant? It says so instead of guessing. Link in comments.

Vishesh Baghel

@VisheshBaghell

I recently got access to jev from and built this, because I hated the hacker news front page. everyone gets the same stories in the same order. someone else already decided what matters, and it is never quite what matters to me so: six sliders. technical depth, drama, practical

Bilal Khan

@Bk23544

JEV is crazy!!! I got access, so naturally I had to try it with the Three.js Grassworks demo. I built an AI Scene Director that takes a simple prompt and changes a whole set of scene and grass parameters to customize the environment based on your instructions. And it’s FAST.

@davidmadurzak

Can you play mspacman with @typesafeai Well kind of. You need about 70ms of latency to play properly, in the video I had an average of ~650ms. The game was paused waiting for a response and then the footage you see is with the pauses removed. I also had to give some hints on

Mike Kelly

@NicerInPerson

Turns out Jev is very good at quickly crawling through an LLM wiki to find relevant content. 10x cheaper and 40x faster than a frontier worker model like Sonnet. So I built a cli tool your agents can use: s1m - High efficiency knowledge recall from an LLM wiki, powered by Jev

@idleshubh

JEV is INSANE. 4,000+ people applied for internship at @tryAlanAI. So we built an in house review console to find evidence of real work at scale. Every square is a real SDE intern application > 3,518 applications checked in 4:54 > 20 surfaced for human review > Estimated Jev

Abol

@abolbuild

🧵 I wanted to understand what makes Jev different from a normal LLM. So I built a tiny real-time game with it. The AI controls the player and has one goal: Don't get hit.
