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.

Listing Match

A real-estate matching tool that applies hard-constraint gates before ranking a buyer's property preferences against listing features and remarks, returning a fit band and a per-feature score for the agent.

Field Advisory

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

Travel Disruption Rerouter

A travel rebooking demo that classifies a trip disruption, checks itinerary feasibility, and ranks concrete rebooking options against a traveler's ordered preferences, returning ordered choices with probabilities.

Community

A data analyst agent with Jev as the review layer

An open-source data analyst agent that keeps Qwen for generating SQL and uses Jev as a review layer at three checkpoints: question clarity, SQL fidelity to the request, and whether the final explanation is grounded in the returned rows.

jev-table-import-mapper

A dependency-free JavaScript library that maps uploaded CSV columns onto your destination schema: a strict normalized-name pass first, then one Jev boolean per remaining source-destination pair plus a guard question per column, leaving uncertain fields visible instead of guessed.

DeepSearcher Jev stopping experiment

8.3k

Agentic search evaluation inside Zilliz DeepSearcher: a standalone harness replaces the ChainOfRAG reflection call with one Jev Noul per round to decide whether to stop within a seven-round budget, then compares stopping behavior, evidence recall and decision cost on 100 sampled 2WikiMultiHopQA queries.

jev vs. open alternatives

Notebook benchmark that compares Jev with open models and specialised tools on five document-pipeline chores: language detection (Choice(12)), page orientation (Choice(4)), RVL-CDIP classification (Choice(16)), bundle splitting and parse-tier triage, with liteparse doing all PDF rendering and OCR work.

Jev in the Wild (arXiv 2609.30216)

A paper analyzing 2,170 public Jev projects on GitHub as of September 22, 2026. It maps how projects use Jev for attribute judgment, scoring, action selection, content filtering, and model and tool selection, and finds public attention concentrated in routing and interface projects rather than tracking project counts.
