Jev Demos

AiNow dates the Jev release to September 2026 and walks live demos of a model that returns a decision instead of the next token.

Show HN for giga-james/jevgpt, an autoregressive chatbot built by repeatedly asking Jev to pick the next symbol from a tiny vocabulary.

Thread on jevchat, which samples one symbol at a time from Jev's choice distribution until STOP is drawn.

A Python experiment that turns Jev into a chat model by repeatedly asking which symbol comes next, including alphabets, sampling modes, and a bench command.

Grayson Ho walks colour sorting, an AI town, a Wikipedia race, model routing, and games, and separates narration from the measured parts.

AI with Rithesh rounds up early Jev loops: a drone, games, a browser, email sorting, and one labelled product benchmark.

Official TypeSafe community Discord for support and discussion, including a Show and Tell channel where builders share demos built with Jev.

Browser playground in the TypeSafe console for trying System One: paste state, define typed questions, and inspect answers with probabilities, confidence, latency, and usage.

A single shared chess game where visitors play against Jev, which weighs every legal move at once as one Choice question and shades the board with its probabilities.

A Telegram channel X-ray that pulls up to 1,500 public posts from the past year and has Jev rate each one, tallying news, ads, jokes, and clickbait into a shareable card.

A free no-signup demo that turns any question into Yes, No, or Maybe by calling jev-latest through TypeSafe's System One API, with live web search for questions that depend on current facts.

A hosted checker and public API that takes a pasted software idea and returns a Jev verdict with success potential, backed by a task guide and a POST /api/fit endpoint.

A live Val Town demo that re-asks 16 typed judgments about your text in a single API call on every keystroke, covering traits like passive-aggressive, AI-written, tone, and urgency.

A semantic mapping playground where you choose any two concepts as axes, add words or phrases, and Jev places each one by how strongly it relates to both axes.

A monorepo of roughly 20 latency-focused demos: moderation firehoses, rerankers, inbox triage, macOS launchers, and closed-loop control simulators, each with p50/p95 telemetry.
