I made Jev control a traffic light using 𝘯𝘦𝘢𝘳 𝘳𝘦𝘢𝘭-𝘵𝘪𝘮𝘦 𝘵𝘳𝘢𝘧𝘧𝘪𝘤 𝘧𝘦𝘦𝘥𝘴, obviously a simulation. It cost me less than a cent to run, and the best part was watching it decide to do nothing when it wasn't sure. Wrote an article about it! Link in reply 👇

@AbretuPotencial

I built an autonomous computer on Jev and the first thing it did was LOSE at king of fighters, but then it bounced back and WON we got self-driving cars before self-driving desktops. @sai_borg is the desktop one 🥊 #robosecretary #saifleet

@chirag

Saw someone comment here that you can make any local model speak TypeSafe Jev's /v1/systemone - so I built it. llamacpp-jev: typed questions → probabilities, text + vision, in front of an unmodified llama-server.

Wahab Khan

@chaosengineerr

got tired of reply guys.. so i built a chrome extension that stamps them jev by @typesafeai reads every reply and hides the low effort ones want it? thinking of open sourcing it

jem 💜🩵🩷

@sheherenow_

jemo 4: someone was like "jev is cool, I wonder what other old ideas are worth reevaluating?" so i guess i made a 1980s Expert System that runs on lisp + jev??? ¯\_(ツ)_/¯

Luis

@luisf_mc

“Where was that tweet I read yesterday?” I built Seen with Jev from @typesafeai to find it. Press ⇧⌘Space. Type what you remember. Open the saved screen. It works across Mac apps and displays. Jev ranks the results using your own TypeSafe or Vercel AI Gateway key. Local

@MargiShah_18

I built a tool with Jev + Reddit that finds conversations where my product might actually be useful. The idea was very simple. I wanted to find someone who is already asking for a recommendation or trying to solve a problem, make sure the post itself is recent, and see if I

@jreyesdev

I just built a demo that uses @typesafeai JEV and @sanity_io and it's incredible. No LLM in the query path. The "agent" skips retrieval entirely when it can, and when it can't, it's one-way (no roundtrips). The prose was already written at ingest, so the agent selects an answer

I Built a Live AI Director With Jev I’m presenting. AI is choosing whether you see me, my screen, or both. I built a little live director using Jev. My voice is transcribed locally, then Jev uses those words to choose the view while I talk. It switches between the views, but

@CallmeSamridh

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

@dealerdefi

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

Kane Snyder

@tenfingers

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

@Divine_machine

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

Technophile

@Technop54777070

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

Mikhaeel

@mmmikhaeel

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

@DevaiahShrithan

I gave JEV at every AI paper since 1993

Shrithan

@DevaiahShrithan

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 🧵

Rishav

@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.

Lovepreet Singh

@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

@GabiDev98

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

@chriscmathew

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

Koushik

@_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

@yatharth170699

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

@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

Jive is an open-source terminal coding agent whose execution graphs mix tool and Jev calls so frontier LLMs handle planning and exceptions while Jev handles repetitive decisions.

An open-source app curates Hacker News stories from a user’s stated interests using Jev.

A plugin asks Jev to choose the Codex model and reasoning effort before a run, with user-set model caps and approval required for Astra.

jev-gc watches agent OpenTelemetry spans and decides what stays in the next prompt, what becomes a pointer and what gets archived.

An open-source app uses Jev to score more than 3,000 emojis against any typed phrase.

A Python/Strands workflow has agents inspect a GitHub pull request, then compares an LLM judge with Jev for severity and relevance before Python applies the final inclusion rules.

Open-source router where Jev picks local Qwen or hosted Sonnet per request, with a UI showing each routing decision.

A public demo asks Jev 18 typed questions about a deployment, including tests, rollback and availability, then converts the probabilities into an inspectable verdict.

A Chrome extension reads the post being answered and uses Jev to rank a corpus of 1,300+ GIFs and emojis. The author reports about 300 ms and $0.0003 per search.
