15 starting points · guides link to our notes first
- Guide · ArticleJEV vs. LLMs as Rubric Judges: Cheaper, Faster, and Wrong in the Same PlacesA controlled comparison gives Jev and three flash-tier LLM judges the same rubric criteria across 5,003 unit–criterion pairs, then separates accuracy, equivalence, shared label departures, cost, and replayed cascade performance.
- Repository · SDKs & clientsBlinkRuns open, Jev-like typed choices in an embeddable C runtime or a browser, with Snake, Doom, and autopilot demonstrations.
- Experiment · Integrationslangchain-typesafeAdds Jev's typed decisions as a LangChain Runnable, with experimental middleware for model routing and tool-risk checks.
- Repository · Agent toolingskill-pickerA small CLI ranks local Agent Skills against a request, then returns suggestions without invoking anything automatically.
- Guide · GuideJev for Git workflows: commits, pull requests, and CI gatesA dependency-free Node and GitHub Actions tutorial that derives bounded PR judgments from a constrained diff, validates Choice, Score, and Noul responses, starts in report-only mode, and calibrates before any gate becomes blocking.
- Repository · Apps & data pipelinesJev Inbox for GmailReorders visible Gmail rows by unread status, criticality, urgency, and user-defined labels without changing messages in Gmail.
- Demo · Playable demos & botsTactiX AutoScalperTactiX used Jev in an automated scalper tested against one-minute market charts on testnet.
- Repository · Benchmarks & researchVejRun Jev-compatible typed judgments locally in a browser or Node server using small natural-language inference models.
- Guide · GuideJev production reliability checklistA compact production checklist for versioning the full decision contract, separating provider failures from valid uncertainty, keeping privacy-conscious reproducibility logs, and rolling out against labeled outcomes.
- Collection · Community listsAwesome Jev SkillsCollects Jev projects, reusable agent skills, and editable decision recipes with an optional validated Python client.
- Writeup · Articles & threadsJev as a semantic ifNicolay explains how agents can use Jev’s typed answers and calibrated probabilities as branches around an LLM.
- Experiment · Humor & parodyWill This Post Upset Her?Check an X draft before publishing to judge whether the maker's girlfriend is likely to be angry about it.
- Guide · ArticleCan Jev Judge Radiology Reports? Evaluating a System One Model for Clinical FactualityA report-evaluation pipeline locally decomposes generated and reference chest reports into atomic findings, asks one three-way Choice for each statement, and aggregates discrepancies in both directions. The design captures unsupported candidate claims and omitted reference findings without counting the same contradiction twice.
- Repository · Browser & computer usejev-computer-useA CPU-first GUI agent where RapidOCR reads the screen, Jev picks the next action, pyautogui performs it and dHash checks the result.
- Resource · Official TypeSafeTypeSafe AITypeSafe AI builds models that make fast, structured decisions inside software.
