Jev AI examples, page 5
407 real Jev AI builds and public demos, updated daily. Original text, metrics, and a link back to each source.
Last updated
Public Jev AI examples and demos, not official TypeSafe docs. Clients and SDKs are in the Jev GitHub projects. Paths for jev-latest, Vercel, and OpenRouter are in the September 2026 channel map.
Agent-skill repositories are listed on Jev skills on GitHub.
OpenRouter model ids recorded for Jev AI are on Jev AI on OpenRouter. Rubric and eval posts are on Jev as a judge. How the company and the model fit together is on TypeSafe AI. The pricing calculator uses the published input rate.
No posts match these filters.
@JeffreyBiles says Jev opens up entirely new question types. The post includes a video.

@jetwaniavinash built jevmem so Claude Code remembers project rules: say it once, it writes JEVMEM.md, and Claude sees it next session.
I kept typing the same rules to Claude Code. "Dates are day-month-year." "Don't push without asking." So I built jevmem. Say it once, it writes it down in your…
@_avichawla shows pg-jev, a Postgres extension that calls Jev from SQL with jev(), jev_prob(), jev_choice(), and jev_score(), and no vector column.
Another insane Jev use case! Traditional database filters need precise, predefined conditions. But many questions are semantic: - Is this article mainly about s…

@NickGideo published question-kit, a developer kit for building on Jev / System One models, and linked https://github.com/Engid/question-kit.
i'm bullish on typesafe and Jev! so I made question-kit, to give developers a kit for building on Jev. go check it out! https://github.com/Engid/question-kit

@kushalbyatnal introduces Jevbox: Jev files uploads into a folder tree and search picks folder, then document, then section, with citations and an MCP server.

@Richelle_Ji says the SF Tech Week filter is now live and free. It uses SimpleJev to filter 1,697 events, including ones that do not exist or are a 1:1 sales pitch.

@DavidKPiano introduces Jevspresso: XState sets what is possible, Jev picks the next move. Try it at jevspresso.dev.
I mixed Jev + an espresso (state) machine. Turns out, Jev's a pretty good barista ☕ Introducing Jevspresso: XState determines what's possible, Jev decides the n…
@Sumanth_077 explains jevgrep: Jev judges which folders, files, and declarations are relevant, then returns source excerpts for the coding agent.
Jev for semantic code search! jevgrep is a CLI for coding agents that helps them find relevant code when they know what a behavior does, but not where it lives…

@kohawithstuff built a browser GTA and made TypeSafe's Jev the brain that drives NPC movement and interactions, in what they call one prompt.
I built GTA in the browser and made JEV AI Model by @typesafeai the brain for the app. drives the NPC movements and Interactions. all built in "one prompt"

@dbreunig sketched a model router in about 15 minutes with DSPy and Jev that picks from the initial prompt, and linked a gist.

@vercel says Jev is in the AI SDK for Python, tested by detecting Python vs English as text is typed and by writing Python one decision at a time.

@rseromenho wired TypeSafe Jev into reportar.pt so each civic report is classified and routed to the right Portuguese entity.
The hardest part of complaining in Portugal isn't writing the letter, it's knowing who to send it to. https://reportar.pt now uses Jev by @typesafeai to classif…
@shawnbuilds made a custom Jev memory harness for Claude Code mods, using TypeSafe via treg, and says the rebuild prompt is below the post.

@MadisonJRickert built a Jev classifier for Claude Code auto mode and says the permission checks it decides are 2x faster.

@DominikTornow's stfu asks Jev on each prompt how long Claude's reply should be, then adds that limit to the turn.
Shut up Claude with @typesafeai. On each prompt, Jev decides how long the reply should be and adds a length limit to the turn. Get an answer, not an essay. http…

@N01ennn maps TypeSafe’s agent docs into nine Jev patterns under one rule: the LLM thinks, Jev decides, code acts — routing, guardrails, gating, triage, and more.
