Paired comparison of Jev and OpenAI structured outputs on 1,000 synthetic outpatient notes, both given the same note, policy, candidate values and ten typed questions.

The Chromium T-Rex Runner game with Jev at the controls: it picks jump, duck or keep running for each new obstacle and chooses a short or full jump profile. The browser keeps speed-aware frame timing, collision geometry and input execution, and manual play still works without a key.
Pre-registered independent check of Jev's calibration and type-safety claims, with the protocol frozen and hashed before the first call. On CLINC150 the chosen-option probabilities were calibrated (ECE 0.0204), on Banking77 they were not (ECE 0.0936, systematically overconfident), and across 8,576 responses there were zero type errors.

An independent, reproducible audit of how well Jev performs in Spanish, with a run of 19,200 calls across four datasets showing measurably lower accuracy when the same instructions are given in Spanish instead of English, plus a CLI to repeat the comparison on your own labelled data.
A pre-registered evaluation of Jev's pairwise hawkishness rankings of FOMC chair press-conference openings, checked against same-day federal funds rate changes and an independently published scoring project.
A Chrome extension that sends LinkedIn feed post text to Jev with a rubric of narrow yes/no and rating questions, then blurs posts it scores as low value, with one-click reveal.
Scores Federal Reserve press conferences hawkish to dovish in real time: Jev rates every word the Chair says in about 150 milliseconds, side by side with a chat model scoring each caption line.
A local Gomoku game for Apple Silicon where Laya-MLX plays white, choosing among up to six rule-filtered candidate moves with a real choice inference call, and the browser shows the model's per-candidate probabilities.
An Android system-wide overlay that reads on-screen text through an AccessibilityService, sends it to Jev, and shows a floating badge when a manipulative interface pattern looks likely, skipping password and card entry screens.

Hassan used Jev to sort 1,018 AI research papers into one of 24 topics for $0.08 in total, with a 256 ms median latency per paper, after DeepSeek V4 Flash wrote the summaries. He was still running evals before swapping them in for the topics on 1kpapers.com.

Free SuperX tool that scores a draft X post from 0 to 100 against a normal post from an account your size, with lists of what helped and what hurt and a simulated feed preview. Rob Hallam's launch post says each draft gets 61 Jev questions in about a second, fitted on 9,481 posts from 207 creators.

An API that routes a request across more than 1,000 AI models from 50 or more providers. Corent's routing layer now uses Jev to decide what a request needs and how confident it is in that route before generation happens, falling back to a safer model below a set confidence level.

OpenRouter and TypeSafe's hosted router, typesafe/jev-router, uses Jev to pick the model and reasoning effort for each turn and avoids switches that would lose the cached conversation. OpenRouter reports it solved 237 of 423 agent tasks against 130 for its own Auto Router.

A browser fighting game where you play against Jev, TypeSafe's decision model, from the keyboard on desktop or mobile.

Compares packaged snacks for kids across brands, sorted by sugar content and filterable by age, allergen and category. Jev scored 3,000 snacks against multiple criteria in 28 seconds for $0.11.

Jev picks the target for the MOSS litter-picking robot, for example switching from cans to bottles on a new instruction. In the newer v0.2 physics replays it also picks each arm action, and the page replays MOSS acting on Jev's real recorded decisions.

An experimental linter for Postgres Row Level Security policies, built with Jev. It sends nine judgments about a submitted policy and table schema in a single request to check whether access controls actually restrict users to their own data, not just that RLS is turned on.

A live trading site where Jev re-reads a Solana token every 5 seconds for its call, dump risk and buyer control. Users write their own yes-or-no, choice or score classifiers, combine up to six into a strategy, and backtest or run it live against every new launch.

A live first person shooter arena where Jev fights OpenJev, an open weights reimplementation running Qwen on SGLang. Matches are shareable by seed and run fresh each time rather than replaying a recording.

A browser tic-tac-toe game where Jev picks its move each turn with the choice primitive over the open squares. A move journal shows the probability Jev gave each square, a blitz mode gives the human one second per move, and every finished round joins a shared scoreboard.

Open source snake game where two Jev agents compete against each other in real time to reach the trophy first, built to show off Jev's low latency in a game that needs real-time input.

A live Minesweeper broadcast where Jev picks every reveal and flag with the choice primitive and everyone watches the same game. A decision log shows each move's confidence and alternatives, a separate checker labels each loss as a forced guess or a missed deduction, and the game pauses when nobody is watching.

Matches you against makers who introduced themselves on X, using Jev to find the ones near you worth meeting.

Community experiment driving the adventure game Kyrandia 2 with Jev choices; the model ends up looping. A useful failure case for real-time control.

The app precomputes numbers like water depth before asking Jev to weigh them, and flags low-confidence decisions for human review.
A small village streamed live to the browser, where five families forage, farm, trade, gossip and raise children and dogs. Every judgment call a villager makes comes from Jev, and a second small model keeps a running newspaper on what happens.
