🎇 I made a small Chrome extension: a side panel that drives any site's WebMCP tools with Jev…
A Chrome side panel that reads the page's own WebMCP tools and, on every keystroke, picks the one that fits, fills in its arguments and says how sure it is. The confidence number reaching the interface is the interesting half. We have not installed the extension.

dzhng/jevgrep
A CLI that finds code by asking what it does, built for coding agents: Jev picks the files and the source context worth reading instead of the agent grepping its way in. The README's headline is a cost claim — "Same intelligence. About 30% lower cost." — measured on their own ten-task SWE benchmark.

I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on n…
A browser extension that hides or collapses posts in the timeline on the reader's own rules — Jev making one decision per post, in the feed, at scroll speed. Worth keeping as an example of the decision living inside somebody else's page rather than a pipeline of ours.

I built a free internal linking tool using @typesafeai Jev for classifying and selecting the …
A free internal-linking tool that classifies a page and picks the links worth adding — an SEO chore turned into one decision per candidate link. The author published it for anyone to use, which is why it is worth having in the column.

I think I just cooked something 🔥 jev(): a PostgreSQL extension that searches your whole dat…
A Postgres extension that judges rows in natural language with no index and no embeddings: one function inside a WHERE clause, a hundred and twenty-nine rows in about a second. The demo is small and the shape is not — a filter that can read what a column means.

Jeff – Jev-compatible 0.8B decision models, trained at home, ~30 ms
An 0.8B Jev-compatible decision model family you can train at home, shipped with GGUF builds, adapters and a hosted playground at jeffhub.ai. It is the most-discussed item in this column — 231 comments — and most of that argument is about whether a model this small holds up on real classification.

realZachi/pg-jev
A PostgreSQL extension that answers plain-language questions about your tables: Jev does the choosing, the database does the work. It puts the decision model inside the database rather than beside it, which is the same architectural bet Cloudflare made by putting Jev behind env.AI.run.

Show HN: Jeff – A read-only CLI for semantic code review using Jev
A read-only review CLI, and the thread argues about the word read-only rather than the model: one commenter points out that in a coding agent an edit is refused unless the file was already read in that conversation. Good thread for the enforcement question.

szczyglis-dev/py-gpt
Not a Jev project: a large multi-provider desktop assistant that added a Jev / System One (inline) plugin for classification, routing, selection, verification and scoring. It is the shape adoption takes once a model stops being news — one entry in a plugin list, and the repo carries a jev topic tag.

This is actually insane. This uses @typesafeai Jev model, as a plugin in Claude to review all…
The most-liked post here: Jev working as a plugin inside Claude, for review work. The interesting part is the shape rather than the excitement — a large model writes, Jev decides.

We built a plugin that gives Jev a browser in Cline, and have been blown away by the results.…
A coding assistant plugin that hands the model a browser, so a decision can be made after looking rather than from memory. The integration is the contribution; the post is a demo and we have not run it.

We just ran Jev on our WebMCP benchmark. The result: basically broke the benchmark. Jev + Mer…
A WebMCP benchmark where Jev paired with a fast small language model solved every task at roughly 112× lower model cost than a frontier model driving a browser with code execution. The benchmark belongs to the company selling the tooling, so the multiple is their number, not a neutral one.

wy-coliney/jev-browser-use
A browser skill that splits the loop in two: Jev owns clicking, toggling, scrolling and navigation, while Codex keeps text input, visual judgment and the final verification. The README claims 5–10x faster browser operations in the author's own product workflows at EZCollegeApp.
