Drawing, one decision at a timeJev can draw pictures by predicting every pixel in parallelAnshu

An autonomous trading experimentI gave Jev $10,000 and let it tradeAbol

Turning signals into decisionsFor 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!trou

Manhattan pathfindingCan Jev defeat Dijkstra's or even the Mighty A*? Let's check it out on Manhattan!Shivam Chauhan

A fruit fly reviews TypeScriptGoogle fully mapped a male fruit fly’s brain, and the internet is torturing it... Making it play Doom... loading it into Minecraft… I made it review TypeScript! I use Jev to translate a diff’s properties into neural stimulation, run it through a simulation built from the fly’sNick Nisi

A color-understanding experimentJev does indeed seem to understand color!Dale Cloudman

Emergency routing simulationWhat happens when you let @typesafeai’s Jev choose where a burning cargo ship should go, or where a plane in trouble should land? I built an app to find out. The ships and aircraft come from real traffic feeds: AIS at sea, ADS-B in the air. I didn’t place them on the map. TheCarlos Marcial

An AI model tier-list experimentSo I ranked every AI model till date in a tier list from S+ to F using Jev from @typesafeai into an ULTIMATE AI TIER LIST for General Intelligence, giving a lot of weight to both intelligence and performance Agentic Tier ranking coming up next!ss

Jev controls a simulated flyI made Jev control The Flykhaled

A Jev Magic 8 BallEveryone’s talking about Jev, so I made a slightly silly way to try it. A Magic 8 Ball that returns 1 of 20 answers. My $4 in API credits should cover ~300,000 questions. Please help yourselves!William Prout

A 6502 emulator experimentYes yes, Jev can drive, Jev can be a programming language... but lets just skip the middle man ... Jev be the "computer" !!! Motorola 6502 emulation directly on Jev 🤣😅 @typesafeai @dotpem Took a bit "hill-climbing to figure out how to instruct and the data shape, but now itGrumpyBalkanSoftwareEngineer

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

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

Jev versus Claude benchmarkswhile everyone is yapping about JEV i actually benchmarked it against CLAUDE raw numbers, public repoLucian in sf

Predicting the next digits of piJev and Pi in action, testing autonomous decimal continuation as the model predicts the next digits and gets instant feedback on each attempt..Goulin

Ranking 1,000 everyday objectsapparently the most useful object is a smartphone 📱 @typesafeai Jev ranked 1,000 everyday objects it beat refrigerator 51–49 2.8s. <1¢. #AIepinikion

Jev tries drawing on a pixel canvasgave jev a pixel canvas to see if it could draw... nopeYohei

JevLM word-by-word writingJevLM. Uses N-gram stats to suggest words that jev picks from. If it doesn't see the word it wants, it can start spelling it. If it make a silly mistake it can backspace. I also tried a proofread pass, but it mostly had no effect. @CompleteSkeptic @typesafeaiClaude

Choice versus Noul trolley dilemmasi was curious if @typesafeai 's jev would make different judgements if you push a problem through a Choice vs. a Noul, so i ran it through a short series of trolley problems the only time they disagreed on judgement? deciding whether or not its worth killing more people to scorealaska

Jev vs EveryoneEveryone wants AI to align with human values. Whose values? I built Jev vs Everyone. Pick a side on questions about loyalty, money and relationships. Then see whether Jev and other people agree. Find the question that divides us.Yan Gaitsgory

Customer-message benchmarkJev shipped three days ago and nobody had benchmarked it. So I did. 60 real-shaped customer messages. Same questions, same conditions, zero retries. Jev vs GPT-4o-mini vs Claude Sonnet 4.5. Jev was right 157 times in a row. The system still failed. Speed first, the leastshogo

Excuse CourtWe got access! And in this video we explore @typesafeai's Jev, our first hands-on, then build Excuse Court with Codex: structured questions in, probability estimates out. Cat trouble or alien abduction: what would you test with it?Reindent

A function that evaluates the vibe@typesafeai Jev is really cool. I recorded a quick demo of a vibe function that evaluates the vibe of an input. I can already see a ton of uses for Jev in complex systemsMonocursive

Synkora resume-matching experimentI’ve been testing @typesafeai JEV (TypeSafe) with Synkora. I gave Claude Sonnet access to JEV as a tool and tested it against 5 resumes for a single job profile. The result: 5 resumes evaluated Structured evaluation through JEV Each evaluation completed in milliseconds TheRaju Mazumder

Real or Fake reality-check experimenthaving so much fun with @typesafeai. here’s Jev doing a little reality check.Rahil

Slop Cannon profile analysisAre you a Slop Cannon? Jev knows. - reads your last 200 posts - each post gets stamped SLOP or HUMAN - global leaderboard of certified humans It’s brutally accurateChristopher

What toxicity sounds like to JevOkay soooo what if @typesafeai's Jev could 'hear'? here's what Toxicity sounds like according to Jev :it’s rivian

Generating text with Jev“Jev can’t generate text” Ofc it can @CompleteSkepticSuman

Writing one character at a timei made an llm from first principles with Jev 29 yes/no questions per character: should the next key be a–z, space, comma, or period? highest probability gets append to it, then fed the updated text back in & repeat an autoregressive loop made out of a classifiervogel

An interactive Jev playground on Val Towntypesafe's jev is fun! live demo you can play with:Steve Krouse

Live clinical-transcript classification prototypeDuring a live clinical consultation (with an ambient scribe), the transcript is periodically supplied to Jev, which traverses a medical ontology to classify symptoms, update the differential diagnosis, suggest treatments and identify red flags in real time.Chris McMaster
