Blitz chess against frontier modelsJev VS Fable 5.1 VS GPT-6 Astra: chess typesafe's new Jev V13 isn't an LLM. it doesn't chat, doesn't explain, doesn't write code — it only makes decisions. so we made it play blitz against frontier LLMs. the test: 5+0 blitz. every move is one API call.

A codebase complexity classifieri built a codebase classifier with Jev and this might be the solution to overengineered code that agents create what should I test Jev on next?vogel≈ 97.5K views on X

Email fraud detection with Jev and KimiJev + Kimi K3 for fraud detection! TLDR: Jev classified 100 emails in 1.42 seconds, then I routed the uncertain cases to Kimi K3. The full pipeline got 96/100 correct for only ~$0.07. Video is not sped up, check out the live run! Here was my process: I gave Jev 100 emails toHassan≈ 58.2K views on X

Stagehand browser control with Jevwe built blazing fast computer/browser use with Jev + @Stagehanddev. this task cost $0.001 and executed at near instant speed (in a remote browser btw) the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then StagehandKyle Jeong≈ 66K views on X

Tetris with real-time Jev decisionsI got early access to @typesafeai's new Jev model and built a demo of it playing tetris The generation speed is so fast that it's pushing blocks down This feels like another "this changes everything" momentMarcus Lowe≈ 78.2K views on X

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≈ 166.2K views on X

Jev inside a security pipelinethese are results of using jev on one of our security pipelines. we already have to use smaller (and dumber) models to make it economic and this model does it over 5x cheaper, faster and while maintaining much higher accuracy. i don't normally hype over new model releases butGreg Pstrucha≈ 82.4K views on X

Jev-review feedback for coding agentsbuilt `jev-review` @typesafeai it's an experimental, local-first MCP plugin that gives coding agents a score quality feedback loop across different metrics. agents call jev while they work, get scored, make improvements, and repeat the loop try below 👇Niaz Morshed≈ 45.8K views on X

Five hundred agents in a 3D environmentJev is actually insane. We benchmarked it, and the results completely change the game for us: > 500 real-time agents > running in parallel > in a 3D environment The preliminary results are crazy: > 500ms average latency > 35 API calls/s > all with a naive implementation WeCris Lenta≈ 58.7K views on X

A Rubik's Cube that solves itselfI got a rubik's cube to solve itself with @typesafeai 's Jev and it solves it like a person does, 94 moves, not the 22 move optimal solution. Jev isn't an LLM, it just answers one question in ~250ms with a probability. so I put the beginner method in code (the one you'd learn onPaolo Rosson≈ 205.5K views on X

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≈ 56.4K views on X
