游戏Jev plays Catan
Sachin
wanted to see what happens when a few Jevs play Catan so I forked...after a while the Jevs just refuse to negotiate with each other and end up doing nothing on their turns 😭 really fun model to play around with!! @typesafeai awesome idea to try jev with games @Vtrivedy10
实验线上Ask Jev
Wayne Sutton
Ask Jev anything. Give it a try at It won't answer. It will judge. Let's see if we can get to 1 million questions. @typesafeai 🤝 @convex work great together. @hmartenjoyer @CompleteSkeptic @justKDeng @mikeysee
效率A jargon-detecting pigeon
Prateek K. Keshari
i put Jev inside a pigeon. it has one job: find jargon in your writing and take a dump on it.
效率JevForm
Tamir
introducing JevForm, a form that dynamically branches and chooses what to ask next usinng @typesafeai’s Jev in my life i’ve made hundreds of forms with crazy if/then logic. Jev solves it. built with @vercel json-render (by @ctatedev), so theoretically it can support any
开发工具线上traffic-guard
Hemanth.HM
Baked traffic-guard: an offline bot gate for reverse proxies with zero dependencies. Uses wire-order header checks, stateless HMAC tokens, and exploit patterns. Blocks scrapers & attacks without breaking real users. Demo: Indeed you can plug jev :-)
数据与研究线上TC39 Atlas
Hemanth.HM
For years I wanted to classify @TC39 proposals to spot common patterns. Using @typesafeai's Jev, I evaluated 324 proposals across 9 dimensions in 12.7s (~25.5 proposals/sec)! #tc39 #javascript #ai
开发工具pkg-gate
Hemanth.HM
So, I baked pkg-gate with @typesafeai! npm lifecycle scripts can run arbitrary code on install. pkg-gate: a ~100ms pre-install gate using Jev 4 typed primitives: - Choice: intent - Score: severity - Nouls: exfil & curl-to-bash $ npx pkg-gate <pkg> #node #npm #security
开发工具jev-codes
Kushal Agarwal
Hey Everyone, Just Built : Audit your git diff against YAML coding-standards packs using TypeSafe's Jev model, from a CLI or your AI agent's command/skill. 1 step install: npx @kushwho/jev-codes Evals are in the repo♥️. Happy building!

Jev Search
fatwang2
Built Jev Search -- free and open source, powered by @typesafeai Jev and @search1api_dev search API. Ask in plain language. Jev picks where to search and ranks what comes back. Try it now:
创意工具On-demand UI flow capture
omar ✌️
I've wanted this for ages and it's finally possible now with Jev by @typesafeai Imagine Mobbin, but it grabs fresh flows for whatever you’re looking for Browser use has always been to slow to pull this off properly. Jev + browser use are insanely quick now I had a lot of
效率Find in page by meaning
Jiayao Yu
ctrl-f has never understood a single query. It matches strings. This one scores meaning: every sentence on the page gets a probability with @typesafeai's Jev, and walks you through the hits. Searching 'exciting' here: 12 matches. Plain ctrl-f finds zero.
智能体线上rtrvr.ai with Jev
Bhavani Kalisetty
Jev is now live on @rtrvrai , our free browser agent. No API key needed. With Jev enabled, our recorded tasks took about 40% less time. Your fastest browser agent got even faster. We paired this new System One model with our Open Source LLMs. The LLM plans and writes the code.
开发工具Magic Jev Ball
Anusha
I made a Magic Jev Ball for code reviews 🎱 Click it on any GitHub PR and ask: "should I approve this?" It checks CI, diff size, and reviews, then lets @typesafeai Jev decide your fate in ~200 ms No more thinking. Just shaking.
开发工具A Jev code-review gate
Kunal Jain
Jev is your code review that costs nothing and never talks I spent a week trying to get a large model to gate its own output. It can't. It's the thing doing the writing. Jev is the opposite. It never writes anything. That's exactly what makes it useful. Jev
游戏线上Jev Chess Master
Leo Lou
Introducing Jev Chess Master, a realtime online chess game leveraging the power of pure System One AI models. You play White. @TypeSafeAI’s Jev plays Black. Explore Jev's decision making traces in realtime with API cost tracked. 🕹️ Try it live: BYOK.
开发工具Typeahead UI
mikegee
"Typeahead UI" with Jez by @typesafeai If you watch closely it already knows what to update *before* I am even done typing it.
效率Semantic spreadsheet formatting
Robert Yang
jev semantically formatting spreadsheet instantly should we put it in @tryshortcutai ?
智能体线上A faster browser agent
Gregor Zunic
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 (this video is at 1x speed btw) Built a tiny open source browser agent. try it below ↓
效率Spreadsheets that read intent
nader dabit
Another crazy @typesafeai Jev example: Predictive spreadsheets Spreadsheets recalculate numbers, not meaning. Jev reads intent. Type "Urgency" at the top of a column and, as you type, it figures out you want each row rated from "no follow-up needed" to "urgent" in ~100 ms.
开发工具Instant context compaction
tamara
found the perfect use case for @typesafeai Jev: instant compaction in 2026, why is compaction still a summarization prompt? Jev can make it instant by scoring every tool call and dropping what’s irrelevant
效率Scoring 3,000 kids’ snacks
Nikunj Kothari
Jev scoring 3000 kid snacks with multiple criteria on in 28 seconds for $0.11 🤯
浏览器扩展An ad blocker with judgment
Zachi
I build an undetectable realtime adblocker extension with typesafe It checks every dom element and classifies as ad/non-ad and removes it if true Extremely fun to work with, expecting an incredible shift in how AI is being used in the future
效率Search your inbox by intent
nader dabit
Jev is really good at intent-based search! How it looks in Gmail: (for a huge inbox you'd prob let semantic search / embeddings pull first but still much better experience)
开发工具Decisions from the command line
Chris Tate
Every agent harness can now use Jev npm install -g ai-cli → ask yes/no questions → choose between options → score against your criteria
智能体Computer use, sped up
sav
If you blink you might miss it Jev + Computer use = 100x faster than any LLM @typesafeai
实验Drawing, one decision at a time
Anshu
Jev can draw pictures by predicting every pixel in parallel
实验An autonomous trading experiment
Abol
I gave Jev $10,000 and let it trade
实验Turning signals into decisions
trou
For those who still didn't understand what Jev from @typesafeai can do, here is the example. Jev can read dozens of structured trading signals and then show intelligent decisions. It's time to make your system actually alive. What a time!
游戏A city on a whale
gokaygokay
Jev x GPT-6 Astra x H3 Max I created a complex decision making game with Astra. It is about keeping the city on a whale alive with decisions. - GPT 6 Astra designed the world - Jev chose the actions - H3 Max Turbo on fal turned one decision from each round into video All of
创意工具线上Higgsfield model routing
Higgsfield AI 🧩
Jev + Higgsfield = solved auto-routing for genAI models. In this demo, @typesafeai’s Jev evaluates prompt and picks the most fit models for video and image generations on Higgsfield.
游戏OpenCode plays Tetris
Tanay Soni
Jev + OpenCode + Browser Harness + Sanbox = 🔥 Watch how OpenCode + browser harness visit a tetris game website, read the control instructions, use gpt-6 to build a game controller for Jev model, and then hand off to play the game. This is all a single shot prompt with no
开发工具Instant variable generation
khaled
another demo for jev for ~instant variable generation
游戏The tactical sentinel
Adi
I built a game were you play against a sentinel in two modes: 1. Default: Sentinel runs a fixed chain of if/else rules. It follows every one of them and still wanders the map looking for me. 2. JEV Live: hands the Sentinel's tactical call to JEV. -> It went and covered the exit.
浏览器扩展Your Signal
Fabio Angela
I got tired of choosing between X's firehose and someone else's idea of relevance, so I built Your Signal. It uses @typesafeai's Jev to score posts already on screen, then applies my rules locally. Reversible, BYOK, no telemetry, open source.

Cambium Jev integration
Steve Keider
Jev @typesafeai is now supported in Cambium as a first-class provider. Keep in code what can be in code. Strict typing. IR and json trace output on every run, as always. Great way to build training data using AI for what you already use it for. Generation engineering is fun!

Mappity
Franci Penov
The app is open source btw. You can play online with few prerecorded responses from Jev in the interactive demo, or you can grab the sources and run it locally with real data.
