A logistics exception gate that reads carrier codes and free-text driver notes in one scan event and decides whether a shipment needs a human, which exception class it is, and how severe the delay looks.
Jev Tools & CLIs#community#python#logistics
Community
A localization pre-review gate that pairs source and target strings and judges meaning, terminology, tone, and placeholders as separate questions, so one failing dimension blocks a release without blending scores.
Jev Tools & CLIs#community#python#localization
Community
A podcast chaptering tool that labels transcript windows and marks boundaries as separate local judgments, classifying content, sponsor, and housekeeping segments without generating prose for the titles.
Jev Tools & CLIs#community#python#media
Community
An insurance claim triage tool that classifies loss type, scores documentation completeness, and flags fraud indicators in a first-notice-of-loss narrative, routing claims without denying any or setting a payout.
Jev Tools & CLIs#community#python#insurance
Community
An agricultural advisory demo that turns sensor readings, a forecast, and a crop stage into a next-action choice plus an urgency score, routing marginal readings to an agronomist instead of triggering an application.
Jev Demos & Experiments#community#python#agriculture
Community
A clinical intake router that picks a care pathway from a patient's reported reason for contact and flags whether the message needs a same-day response, without ever assigning a condition or a treatment.
Jev Tools & CLIs#community#python#healthcare
Community
A warehouse pick-verification step that compares a scanned item, the bin's expected contents, and the order line to decide between accept and re-scan, catching confusable picks a barcode alone would pass.

Claude Code PreToolUse hook that asks Jev one Noul on whether a Bash command is strictly read-only and auto-approves at p of 0.95 or higher. It can only allow or stay silent, never deny, so unknown or risky commands fall back to Claude Code's normal permission prompt.
Jev Tools & CLIs#community#claude-code#hooks
2GitHub stars
Jev-style medical QA implementation on Qwen3.5-4B that selects an answer from candidates in one forward pass instead of generating text. It reports 69.42% accuracy versus 67.41% for standard generation and a 10.37x speedup across 153,889 questions from nine benchmark sets.
Jev Models & Reimplementations#community#medical#benchmark
12GitHub stars
Apache-2.0 ModernBERT fine-tune that answers noul, choice, score and multi-label questions with a probability for every option. It serves Jev's POST /v1/systemone locally so TypeSafe's Python SDK runs unchanged, reporting 0.026 expected calibration error on its test split.
Jev Models & Reimplementations#community#calibration#modernbert
Claude Code plugin whose UserPromptSubmit hook asks Jev a Choice over /effort levels (low, medium, high, max, unclear) plus a Noul on whether a hands-off request has a fuzzy spec, then offers a one-key switch before Claude starts when the tip clears its confidence threshold.
Jev Tools & CLIs#community#claude-code#plugin
Pre-registered benchmark adding Jev 1.13 to Stanford MedHELM's MedHallu results: one Noul asks whether a proposed answer misrepresents its PubMed abstract. Jev scored 92.9% on 1,000 test items at a 204 ms median and USD 0.03 per 1,000 checks through OpenRouter.

Ascend NPU fork of the Laya decision checkpoints that answers Jev-style Choice, Score and Noul questions in a single forward pass on Huawei 910B hardware. It reports 37-47 ms median for a four-question request, 33.8x-70.9x faster than one container CPU thread.
Jev Models & Reimplementations#community#ascend-npu#decision-model
192GitHub stars
Python multi-agent runtime that ships Jev natively in an optional extras install: agents ask typed Choice, Score and Noul questions through a shared decision client, the Kernel can pick specialist subagents by Choice, and RAG passages with a prompt-injection Noul above 0.70 are withheld.
Jev Integrations & Adapters#community#framework#mesh
3GitHub stars
Measured robotics study that runs Jev as the decision layer for a 10,000-robot warehouse fleet over 41 bilingual incident templates and publishes a crossover against a self-hosted ModernBERT: 0.527 s p50, $24.57 per million decisions, and 91.3% agreement with template labels.

Focus mode for Omarchy and Hyprland that judges each screen against the task you declared and escalates from a red reticle to a window haze and, as a last resort, closing the drifting browser tab. Each check is one Jev on-task classification, with screenshots OCR'd locally and never uploaded.
Jev Integrations & Adapters#community#focus#linux
9GitHub stars
A Jev-style typed-decision baseline built on the frozen Qwen3.5-4B checkpoint that accepts a local image path directly, letting the vision-language model score declared options without generating text. Ships scoring modes, a WebGPU browser demo and benchmark results measured on an RTX 3090.

A chatbot with no language model: every word is picked from roughly 4,700 options by Jev Choice questions, with confidence-driven lookahead, beam search across sentence directions and a self-critique loop that rewrites weak sentences. Code for the paper and the live demo at talktojev.com.
Jev Demos & Experiments#community#chatbot#research
77GitHub stars
An Apache-2.0 0.8B decision model that returns calibrated probabilities for yes/no, choice and score questions on CPU. Distributed as GGUF for llama.cpp and served behind a Jev-style /v1/systemone API, so existing Jev clients mostly need only a new base URL.
Jev Models & Reimplementations#community#gguf#local-inference
4GitHub stars
A pre-release Python framework for predictions on mixed text and tabular data: Jev Noul and Score questions turn text columns into numeric features, then a tabular foundation model such as TabPFN learns from labeled rows in context. Offers hosted and fully local backends.
Jev Repos & SDKs#community#tabular#predictions
3GitHub stars
The first Chinese-language calibration benchmark for Jev-class System One decision models: 378 items and 467 questions across voice routing, e-commerce service and content moderation, with accuracy, ECE, Brier, NLL, AUROC, option-order and zh-CN/zh-TW robustness metrics.
Jev Benchmarks & Evaluations#community#benchmark#calibration
A local winner-stays-on tournament where up to 2,569 animals fight one on one and every fight is one Jev Choice between two names under arena rules held in state. A measured 1,999-fight run took about 16 seconds, 64 API calls and roughly US$0.01.
