Public Jev AI examples and demos, not official TypeSafe docs. Clients and SDKs are in the Jev GitHub projects. Paths for jev-latest, Vercel, and OpenRouter are in the September 2026 channel map.
Agent-skill repositories are listed on Jev skills on GitHub.
OpenRouter model ids recorded for Jev AI are on Jev AI on OpenRouter. Rubric and eval posts are on Jev as a judge. How the company and the model fit together is on TypeSafe AI. The pricing calculator uses the published input rate.

@rafalwilinski says TypeSafe Jev now runs a massively parallel browser-based adversarial test suite that tries to break each release, and that it costs pennies.

@PaliwalMuskan19 built a skill-picker because keeping 30 or more agent skills meant remembering which one does what. They say Jev (@typesafeai) ranks those skills for a given task and tells them and their agents which skills are actually worth using. The repo is github.com/MuskanPaliwal/skill-picker.
built this skill-picker for myself because apparently having 30+ agent skills also means remembering which one does what 😭 jev (@typesafeai), being the god that…
@CartwrightApp built Cortex, a local MCP server: Claude plans, and a fast layer does the clicking. On the same Mac-app task they measured computer use at 23 seconds versus Cortex at 0.8 seconds, and one action from about a 5 second Claude round to 0.25 seconds with no model. They list 24 tools, including a browser, Mac apps, GitHub search, and a safety gate, say it was measured on their Mac, and tag @typesafeai and #JEV.

@TheMattBerman says Jev broke down 724 live ads from 37 brands in 40 seconds for 9 cents: hook, format, offer, CTA, awareness stage, and landing-page mismatch. They say it will be available in StealAds and MCP.

@OpenRouter says Jev by TypeSafe is on OpenRouter in beta. It takes app state plus a typed question and returns a typed decision with a probability, with no JSON prompting or parsing layer.

@kunchenguid introduces compact-adviser, an agent plugin for Claude and Pi that uses Jev to judge whether a session is at a task boundary safe to compact. They built a private eval from 40 real sessions and say the classifier favors precision when the window is small and recall as it fills up.
almost every day i hear people ask "when should i /compact my session" there's no easy answer because it depends on how likely your future action will need deta…
@abbas_kazmi066 demoed Hover Explanations with Jev, reporting about $0.006 for a simple demo run and calling it cheap and fast.
plenty of use-cases for JEV. here's one: Hover Explanations. This simple demo testing cost me around: $0.006. Definitely very cheap and fast.
@yannnis built a Jev product that scans Reddit for leads, contrasting it with going viral on LinkedIn for slop content.
Enough is enough! Is it that LinkedIn sucks or what? Let's settle this. I go viral on LinkedIn for slop (attached) Then I spend 2 days to build a JEV product to…
@nedwize built a tax-document classifier with Jev on top of an existing LLM ingestion pipeline. They say Jev classifies 100% of their corpus at $0.001 per page, 34x cheaper and 6x faster than the LLM setup, and that they are open-sourcing it.

@DanRaeder says that while Jev is down for new invites, they worked with Claude to build Vej, a Jev clone that runs locally. They call it weakest at score types and almost 1:1 for noul and choice, and say you can use it to build and play with Jev-based apps until you can get in. The repo is github.com/draeder/Vej.

@Saccc_c compares Codex’s built-in computer use with a “Jev Use” setup that pairs Codex and Jev. In a video of adding a Mac calendar event, they say the Jev version has almost no pauses and similar token use.
卧槽，居然真有比Codex内置computer use更快的操作电脑的方式 我尝试用Codex+Jev打造了一个加强版computer use，我称之为「Jev Use」。比内置的更快更丝滑，token消耗却差不多 下面是我用「添加Mac日历事件」做了一个对比视频，同样的内容，明显可以看到Jev版本整体过程几乎无任何停…

@itsrohanm made a small word game called Clue Me to test Jev. It works like charades and taboo: you describe your word without using it, and Jev tries to guess it. The game is at yorohan.com/clue-me. They mention @CompleteSkeptic and @typesafeai and say they cannot believe how fast Jev is.

@maubaron shows Jev playing Smash Bros. against itself, controlling all four characters and choosing moves in a fraction of a second. They say the match used over 22 million tokens and cost a couple of cents, and that Jev does not replace GPT-6 Astra.

@marcelpociot built a macOS app that watches Downloads and custom rules. If Jev decides a file is an invoice, it moves it to a folder with the right filename. They say no other LLM calls are involved.
Jev unlocks SO many awesome new ideas. I built a macOS app that monitors my Downloads folder along with a customisable set of rules. Is the downloaded file an i…
@mightyking says Jev classified 1,891 ads from Resilia’s ad library in 19 seconds for $0.12, by customer-journey step and ad style, plus an account analysis. They say it is coming to the Maxfusion MCP.

@sarvagya_kul says they gave Jev 400 companies and one candidate profile. In 12 seconds and for $0.0005 it predicted which jobs the candidate was most likely to get, assigned confidence, and flagged mismatches. They say it is coming to @textbackdoor.

@gregpr07 built a small open-source browser agent with Browser Use and Jev. Finding flights took 7 seconds and cost $0.0039. The action space and DOM state change every step, with a small LLM fallback for typing. The video is at 1x speed.

@jetwaniavinash built a Claude Code memory gate with Jev: each message is asked whether it is worth remembering, then skipped or saved as one line in JEVMEM.md.

@dabit3 shows predictive spreadsheets with TypeSafe Jev: type a column header such as “Urgency” and, as you type, each row is rated from “no follow-up needed” to “urgent” in about 100ms.

@robj3d3 describes Jev plus SuperX: every post gets 61 questions in about 1 second for $0.0004. They say it was fitted on 9,481 posts from 207 creators, picks the viral post 2 in 3 times, and does not reward reply bait. The loop is write, score, rewrite, stop at the peak, free with no signup.

@virattt added Jev to the AI Hedge Fund. The flow they describe is set a strategy, pick tickers, then backtest with Jev, and they say the system now runs in seconds instead of minutes.
