What I’m doing with #Jev from @typesafeai:
Making Ergod, my multiplayer AI agent, better at the work between “let me check” and actually getting it done.
Better research. Clearer comparisons. Fewer dead ends.
Small decisions. Bigger capabilities. 🧵
A result can match your keywords and still miss your question.
Jev helps assess what’s relevant. Alongside better page reading, Ergod can focus on useful evidence in long articles and wiki pages - with headings and tables kept in context.
The follow-up is where this gets interesting.
“What about the exceptions?”
“Where did that figure come f
I taught SQL to ask questions using jev:
SELECT * FROM tickets
WHERE jev_bool(body, 'Is this customer angry?')
No embeddings. No keyword list. No LLM writing SQL.
jevsql: natural-language predicates, a typed control plane that never lets an LLM touch your data...

made a color palette generator using jev, because why not?
given the input, jev returns probabilities over ten hue families, scores for warmth / light / energy, and a font pick.
code maps that onto oklch and paints the page. https://t.co/lAe0TlYKdz
Seeing how many people are using Jev to control browsers I wanted to try too.
Wrote the wrapper for 'dev-browser' and called it 'jev-browser'.
And then tried to put it to a test:
"Find the best pricing model for WP Multitool for someone who runs 3 sites, spends 3h/yr on each, and has $50/hr rate and will run them for 2 years."
I saw that it did the right steps until the last one. Was adding the Lite version to the cart.
That's how I discovered that while my Pricing page LOOKS good it's structurally awful and definitely nor readable for BOTS or SCREEN READERS.
Learned something = PR
I made an experimental model router for @pidotdev using Jev as the decision maker.
It's not a generic "pick a cheaper model" router. It isolates work into logical threads and prices cache reads/writes, cold context, expected output + the cost of switching back.
@CompleteSkeptic @typesafeai This wouldn't of been possible without Jev, it's an amazing primitive to make software with 💪🏻
Every company writes copy rules. Nobody enforces them after launch week.
So I made the reviewer that never gets tired. It reads your marketing site on every PR and names each sentence that makes a claim with no evidence beside it. It's using Jev from @typesafeai
It doesn't know your facts. It knows what a claim without proof looks like.

@MParakhin don't hate me
Proof of concept using Jev by @typesafeai to analyze image metadata and estimate how likely an image is to be AI-generated. Built with @laravel, @inertiajs, and @vuejs. Hosted on Laravel Cloud. Thinking of using it to screen photo competition entries.

Using Jev from @typesafeai to improve matching performance, accuracy and cost in our automated @blackbaud RE NXT CRM integration.

Doc-OCR router using Jev @typesafeai
A Jev-powered router that looks at a PDF page by page, decides which pages actually need OCR, extracts the rest locally.
Result: save cost on # OCR pages + speed https://t.co/ZjXqHSjSGh
have not seen anyone actually using Jev for robotics outside of a simulation, so here is Jev running with no policy, zero-shot controlling the robotic arm.

I started using Jev as a tool call for our users on supercenter. And oh boy are they gonna love this. https://t.co/JXnhrZXogy
i built a website that ranks all 1,025 Pokémon by literally any question you type, using jev
it thinks mimikyu is most performative https://t.co/F0qca4H84o
my video on the routing tool blew up on YT!
i crossed 10k views in less than 19 hours, i still can't believe it - my most viewed video till date yayee
have been consistently doing YT and content in the ai space for last 7 months and finally get to feel this😇
i built this tool yesterday called agent router using jev + herdr, i was awake until midnight doing recording, and publishing the video. today it feels all the efforts are worth it
tenet using Jev is up to 275x cheaper and 104x faster than Claude agents 🤯
Same 2,000-line diff, same rules. tenet: 1.5 s, $0.0036. One Claude Fable 5.1 call: 157 s, $0.99. Your agent fixes its own review findings before you ever see the diff. https://t.co/Rr1BpU53ak
I built a real-time chat where Jev judges every message in before the room sees it.
❌ No keyword lists
✅ Rules are plain English
✅ Unsure? Held for a human
Built with Jev (@typesafeai) + @convex + @vercel
Try to break it 👇

Built jevscan - a Chrome extension to detect malicious addresses and transactions on @etherscan in real-time using Jev from @typesafeai. https://t.co/gGgITyJgjT
Spent a day building tenet, a review gate for code that agents write. It judges each commit, commit message and PR against rules written in plain language, using Jev by @typesafeai.
The rules come from @poteto's unslop skill, @hvpandya's stop-slop, @dillon_mulroy's anti-slop and @mattpocockuk's new /pr skill. It also generates rules from your AGENTS.md or CLAUDE.md, and you can write your own rules and presets.
Here an agent trips four of them, gets blocked in 1.07 s for $0.0003, and fixes its own findings.
My first real experiment with Jev: project scorer. It takes the specs, source code, and graph (Graphify output) from a codebase, then analyzes them using Jev, Lizard, and Networkx to create project "quality metrics" based on a configurable rubric. https://t.co/lCryvd749u
i made a smart calculator notebook using jev
it can calculate ANYTHING!! 😅 https://t.co/0kxyblZVjN
