Are the benchmark numbers real?

No. The repo states every headline result is author-reported and unreproduced, and calls out which projects publish raw outputs. Start with those, then rerun the claim on your own data before trusting it.

How do I pick the right pattern instead of copying demos?

Use the decision-shape table: routing and triage, supervision, security, code tools, search, classification, computer use, and more, each with evidence, code, and pitfalls. The model-selection page covers Jev versus LLMs versus classifiers.

What can Jev actually answer, and what can it not?

It covers exactly three types: Choice over up to 255 options, Score over a 2-10 level rubric, and Noul yes-or-no probability. All questions in one request run in parallel against the same state.

What is the most common way teams misuse Jev?

Read the failure-modes and evaluation pages first. The repo stresses question wording matters more than model size, with one experiment moving accuracy sharply by asking four Nouls instead of one Choice.

How current is this catalog?

It is a research snapshot as of 2026-09-18. Jev is in early access and moving fast, so prices, limits, and aliases will change, and every claim links to its source.

How credible are the listed project results?

Every result is self-reported by the project author and none has been independently reproduced. The projects are launch-week artifacts built in the first 72 hours, and the repo points readers at the ones that publish raw outputs.

What guidance does the repository collect?

A what-is-jev primer, a five-minute getting-started, a design method, proven patterns, failure modes, a model-selection guide, and an evaluating-jev guide, plus a question catalog, a use-case catalog, and runnable examples.

About this project

Jev is not a chatbot. You send it program state and typed questions; it returns typed answers with calibrated probabilities in 70–500 ms. This repository collects what people have actually built with it, and - more importantly - how to use it efficiently and effectively. Status: research snapshot as of 2026-09-18. Jev is in early access and moving fast. Prices, limits, and aliases will change. Every claim below links to its source.

Highlights

State plus typed questions in, typed answers plus probabilities out, with all questions evaluated in parallel isolation.
Three primitives only by design: Choice with per-option probabilities, Score with distributions, Noul with yes probability.
Use-case pages per category with decision shape, evidence, code, pitfalls, plus patterns and failure modes.
Showcase of community builds from browser agents and reviewers to rerankers, firewalls, and local reproductions.

Watch out

Every project result is self-reported by its author and none has been independently reproduced, so read the entries with raw outputs first. Jev behavior, prices, and limits move fast, so confirm against current docs. Copy reviewed against the repository README on 2026-10-04, not from running it.

How Jev's Launch Landed

Oct 11, 2026

The first ten days produced three receptions that rarely meet: a Product Hunt launch, a 620-point Hacker News thread, and a r/LocalLLaMA that doubted the framing. Reading them together.
