Ad account X-rayJev has reinvented competitor research! We leveled up my ad autopsy and turned it into ad account X-ray. I gave it meta ad account – it classified almost 700 active ads. And made a complete evaluation of the whole account. The whole process took 12 seconds and cost me justVlad Dubchak

Combos FPSjev is insane 🤯 Same Combos FPS. Astra left. @typesafeai Jev right. Reasoning model vs decision model — not even close. Jev does not replace astra, it opens a different game.Combos Fun by Converge.AI

Jev ArenaI've had access to Jev by @typesafeai for about 30 hours now and I can't stop thinking of the million places it can be used 🤯 Meanwhile, checkout this fun snake game I built where 2 Jev's compete with each other to take the trophy 🏆 Try it out here 🔗Raihan Khan

An X post classifier💩 X Posts Jev Classifier without image/video context it fails bc it does not have the full `context` add typesafe API key and have fun, repo below 👇rolo - eu/acc

News matching for brandsJev is INSANE. 🤯 in 24.9 seconds it read 384 news from this morning and told 15 brands which stories to hop onto today, for $0.19. Claude Opus 5, running on the same feed at the same time, got through 4/384 and cost $0.77. per headline that is ~390x cheaper, and the answerElvis

A drone in an asteroid fieldJev flying a drone through an asteroid field. 300ms decisions. Left / right / slow / accelerate. You can watch the decisions happening live on the right. Green = Jev’s own confidence. Purple = “I’m not sure, ask the big model.” 99% of the time, Jev steered the drone on itsMahmoud

An AI-writing slop detectorYou can use Jev to flag all the slop that Opus likes to writeChase Lean

NoFlow intent-driven buttonsI put Jev (@typesafeai) between a button and a modal. What could go wrong? NoFlow lets buttons express their intent. It makes the model freely pick the most appropriate behaviour from the click + app state. “Buy Pro” → “Try free” can change behavior without touching the code.casungo

A personal email client with smart filtersNow it's my turn. Jev sorts my inbox very quickly and accurate and also let's me add custom filters? I was working on my own mail client for private use for mac and linux and today i wired it up to use jev to sort my mailbox as i need it. Also in there are AI replies (notNick ✪

Reply sentiment at a glanceYou can just do things with Jev! I built a tiny Chrome extension that adds sentiment analysis directly inside X replies. Every reply gets classified as: 🟢 Positive ⚪ Neutral 🔴 Negative Powered by @typesafeai @CompleteSkepticAadhil

A feed filter for engagement baitI built a real-time filter for X with Jev as you scroll, it spots engagement bait, rage bait, and promo posts, then throws them into a trash bin. and it's open source so you could BYOK ⬇️Daninal Hung

Sorting 63,000 emailsWOW 🤯 i just used Jev + @agnt_gg to categorize 63,045 emails in less than 3 minutes for < $1 total runtime: 2 minutes 54 seconds input tokens: 23,430,692 output tokens: 4,528,206 total tokens: 27,958,898 estimated cost: $0.9841 this would have been hundreds $$$ in LLM costsNathan Wilbanks

Backlink outreach scoringJEV is INSANE 🔥 we gave it 1,873 backlink outreach emails to see which ones are more probably to get a reply (0-100) for each one it analyzed: → website and article relevance → how natural the proposed placement felt → contact message fit → personalization quality →Nico More

Natural-language camera controlJev added more precise camera controls and ~230x faster planning to an editing tool I built on top of @mintdotgg! Jev converts natural language to precise camera movements (ie spelling ASTRA) by answering a few calibrated multiple-choice questions (move kind, plus direction andAlex Carrabre

Hipershopping with Agentcardbreaking: Agentcard + Jev + Kernel = Hipershopping ⚡ asking an agent to go buy stuff for you online is usually: - expensive (bc of tokens going back and forth) - slow (bc of tokens going back and forth) - unsafe (bc there's no safe/compliant way to share card info w/agents)IT guy

An AI-writing detectorCan Jev replace Pangram to detect ai? one question to @typesafeai Jev: "was this written by an AI model?" the split is the probability. no training, no classifier, 250ms, $0.00003 per text benchmarked on human vs GPT-4 / Llama / Mistral: 94% accuracy, 1% of humans flagged.Paolo Rosson

Focus Rail train routingThis made me try a different experiment: Can Jev play a game in real time? In my new game, Focus Rail, Jev has to track multiple moving trains and route each one to it's correct station. There is no route solver or fallback autoplayer. Jev chooses the switch settings itself.benkigera

Abide coding-agent rulesbest coding agent use case for Jev: enforcing rules a linter can't coding agents tend to break rules and some rules can't be codified Jev can now score every turn against such rules and tell the agent what to fix asap open-source:Ohans Emmanuel

GODMODE civilization simulatorI used Jev to give a tiny civilization six minds. Then I played GOD. Kindness earned trust, Tyranny sparked rebellion and an apology didn’t convince everyone. Jev decides how each faction reacts and the simulation brings it to life. Try GODMODE in replies ⬇️ @typesafeai #jevGrover

A decision layer for memoryPutting jev to work in our memory systemDekan 🌶️/acc

Dino: Jev vs GPT vs humanGot @typesafeai jev-latest access today So I made jev play the dino game against a gpt-5 model and a real human and the results are shocking!!Priyansh

Recipe scoring on five dimensionsmade some time to test jev from @typesafeai used theMealDB and sent each recipe to Jev to score on five dimensions: quick, cheap, healthy, impressive, and beginner-friendly, while filtering out desserts, sauces, bread, etc. The whole run took just over a minute and costSasha

AgentRun reusable workflowsToday I’m excited to show you our new harness called AgentRun, built with @pidotdev and @typesafeai's Jev. It’s built for an agent to learn how to do a job, code itself a general solution, and then get out of the way.Miguel Ríos Berríos

Live Bitcoin headline classificationWanted to see how fast Jev (@typesafeai model) actually is, so I fed it 30 live BTC headlines one at a time: 16 seconds 10 at once: 2.5 seconds each call gives back a BTC yes/no, an event type and a bullish/bearish call, about half a second each Soo fastAyoub Malik

Android end-to-end testingWas curious how jev performs for e2e testing on a real android device. Both started with the same prompt and 15 test steps. Well, jev was ~14.8x faster than deepseek + vision navigating through wikipedia.Kevin Kern

Jev as a language generatorWho said that @CompleteSkeptic System One model Jev cannot be a LLM 😜?Alejandro Fanjul 🛸

Jev-thoven music compositionJev-thoven composed this entire 2 minute song from first principles.cocktail peanut

Preflight personality simulationAdded Jev to Preflight a project im working on that simulates 1k+ personalities making human-like calls off public datasets. Jev’s killing it. Leading with Jev has boosted confidence at least 30% and responding in SECONDS.Hindrix

Finding viral content in 11 million videosjev is bloody INSANE we gave it a library of over 11 million videos on t1ktok & 1nstagram and asked it to find viral "bloom nutrition" content. in 20 seconds, it gave us over 384 videos, breaking down the hook, format & angle that made each one go viral. (and it only costedDeniz Sancar

Pixel art with a sketch-and-refine loopI gave Jev the ability to draw pixel art! It uses deepseek to plan a sketch with some primitives, then renders it, refines it, all based on pixel positions and colors. Long way to go but it's pretty neat.Astropulse

Scoring a frontier-AI essaywhat does jev from @typesafeai think of the pacing the frontier article by @DarioAmodei?Nicholas Dunzelman

A webpage becomes a fight sceneJev can generate a fight scene on your webpage. It asks each block: floor, button, or ignore? Then each hunter asks: chase, wait, flank, or retreat?Anson

Jev vs OpenJev in an FPSMade Jev fight OpenJev in a first person shooter.Neel Patel

Byte predicts rock-paper-scissorsCan Jev read a human? Play rock paper scissors against Byte. Every round he predicts your next throw before you make it, then plays against that read. His move is committed before you pick, so he can't change it after. Stakes settle over Ark. Try it 👇Carlos Marques

A browser-agent stress testPeople keep thinking Jev is useful for browser use! It is not. It completed about 5 actions before collapsing in a non-cheated test. It's a cool model but not for this.SSH

Reward-hacking guardrails for agentsInspired by this research (and priors), and, @GoodfireAI catches reward hacks in the activations, but closed coding agents don’t give you those. So I built the other half: structural denies on graders/hidden tests + a @typesafeai Jev sidecar that scores tool trajectories asBasit Mustafa
