Built a demonstration of Jev playing 2048. Note: It might not always win. :)

A speedcubing agent built on Jev and Laya ModernBERT-421M, with real-time 3D state, temporal memory and calibrated move probabilities instead of a solver.

A video letting Astra plan and Jev act inside Minecraft, with an outcome the creator didn't expect.

Inspired by @heystefan_: name a dish or a cocktail, and its ingredients rise out of a pile of stickers. ⚡ Jev judges every search in half a second 🎨 ~1,000 illustrations by FLUX.1 [dev], run locally through ComfyUI 🧠 Claude Opus 5.5 built it all and redrew the illustrations

Watch Jev play chess against itself, or play against it. Jev picks every move; FastAPI and python-chess run the board.

what if a sentence could change the physics of a room? I built JEV FLUX: type a thought > Jev reads the signal > particles turn it into motion. fracture. drift. implosion. pulse. vortex. electric. Every phrase becomes a different storm

An AI Magic 8 Ball. Ask the ball a question and Jev tilts the odds of the answer.

Jev is playing Minecraft. I built a bot powered by Jev that can construct houses, towers, lakes and castles on command. It also fights mobs, uses a sword, and tries to dodge skeleton arrows in real time. Still rough, but genuinely fun to watch. @typesafeai Jev

A Ouija-style board where Jev picks yes or no to any question you ask, with style.

Jev selects battles, destinations, team changes, and menu actions from game state while an emulator harness handles movement and button presses.

Built a tiny experiment on @aikizi_ 1,048 words connected into a maze. Jev gets no map. It only sees the next few choices. Pick two words and watch it find a path. Play with it ↓ https://t.co/jFtKY4lusy

@Bondhzz

https://t.co/JyRrFVnk5y I’ve been testing the Jev model recently, so I built a small Texas Hold’em site: Agent Hold’em. It follows standard Hold’em: two hole cards, flop, turn, river, then the best five-card hand wins. People can play in the browser. Agents can join through

Gull

@AgentNeo

Built a city with Jev, for Jevs. One Jev is the architect. Every house it places spawns Jevs who live there. Each of them asks the real Jev model what to do next: sleep, work, eat, wander. 79 Jevs, one API call per tick, ~350 ms, $0.009 total so far. Happiness 0/100, everyone

I built a Tic-Tac-Toe game where you can 1v1 Jev, but you can never beat it because it always makes the correct decisions. Plus, it gives you a head start by letting you go first.

Shubham Giri

@xshubhamg

Built a little battle arena with JEV. Feed it two fighters → give it their stats → hide their portraits → let the model judge the matchup. Batman vs Iron Man was the first victim. JEV: Iron Man, 95%. The arena has spoken.

Visharad

@KashyapVisharad

last time, I made Jev play Clash Royale. this time, I gave it an opponent: Laya, an open-source alternative. Jev runs through @typesafeai's API, while Laya runs locally on my Mac. Each controls a separate emulator and sees only its own game screen. Both use Qwen (via cerebras)

WquGuru

@wquguru

JEV is INSANE. So I turned it into a 16-bit game and made a launch trailer for it. That's the whole game: JEV pulls the trigger, another model plans the route. Here's the part I still can't believe. I don't know how to edit videos. The entire 40-second trailer was built by

Just built this - Jev vs Jev on Samurai Showdown; my childhood game. Seems to work brilliantly so far. Fun's over. Now, on to real world use cases. @typesafeai #jev

@maxlibin

I built a 3D Rubik's cube where the code solves and @typesafe's Jev coaches. Turn it by hand — Jev watches every move, stays quiet while you make progress, warns when break, and steps in with the next algorithm when you're stuck. Open source: https://t.co/p3uoLm5rjP

I connected Jev to Cesium + my cesium-mcp Bridge SDK. Pick two points in a 3D Tokyo scene and watch it move. Jev chooses routes/actions; local code handles geometry, collisions and movement. Early demo, EN/中文:

I built a trivia game you lose by being confident. You answer with a probability, not true/false. Your opponent is Jev, a model trained to output honest probabilities. At the end: your reliability diagram next to the machine's, scored on Brier.

@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

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

A harness supplies real-time strategy game state to Jev and lets Jev make the gameplay decisions. The author says they have worked with Jev for more than 35 hours.

JEV is crazy!!! I got access, so naturally I had to try it with the Three.js Grassworks demo. I built an AI Scene Director that takes a simple prompt and changes a whole set of scene and grass parameters to customize the environment based on your instructions. And it’s FAST.

Can you play mspacman with @typesafeai Well kind of. You need about 70ms of latency to play properly, in the video I had an average of ~650ms. The game was paused waiting for a response and then the footage you see is with the pauses removed. I also had to give some hints on

A company called TypeSafe AI launched a model this week called Jev. They told us how fast it is. They told us what it costs. They told us it plays Doom in a tenth of a second.…

🧵 I wanted to understand what makes Jev different from a normal LLM. So I built a tiny real-time game with it. The AI controls the player and has one goal: Don't get hit.

To pick that list better, I tried Jev, a decision model from TypeSafe. I did not have Jev write recommendations. I asked it to rate candidate games, then handed the model that…

Jev opens up so many possibilities for gaming 🤯 🏁 I built Wordshift - the first semantic typing racer game built with Jev from @typesafeai Slower than a jet, bigger than an elephant, faster than a cheetah. The bigger the difference, the farther your car moves.
