Jev Reviewer
Data extraction for systematic reviewers, built on Jev. It answers extraction forms and risk-of-bias templates like RoB 2, ROBINS-I, QUADAS-2 and TIDieR against a trial report and its supplements, with every answer a verbatim quote and page number to check against the source. Files stay in the browser.

dannote/jev
Jev for OTP, published on Hex as jev. The model is a peer process: you reply to it from a GenServer and its answer arrives as a message you pattern match on, so clause order becomes the routing and thresholds become guards.
Tool
openjev (zhihz): local bilingual probability decisions
Research preview that takes context, questions and candidate answers and returns probability distributions, running on a frozen Qwen3-4B-Instruct-2507. README states it contains none of Jev's weights or RLCD implementation and claims no performance lead.
safzanpirani/pi-jev-skill-picker
Ranks Pi agent skills for the task in front of it, using Jev to pick which skill to load.
zadescoxp/Jev-Trades
A Next.js dashboard that streams one-minute crypto candles from Yahoo Finance and applies TypeSafe decisions to a simulated paper-trading portfolio, gated by a confidence threshold per risk profile. No live broker or order API is connected.
ProjectConfidence-gated actions
leepokai/jev-guard
Security hook for coding agents that risk-scores every tool call with session context (deny/ask/allow), flags prompt injection in tool results and checks skills and plugins. Supports Claude Code, Codex, Copilot, Gemini, Cursor, pi, OpenCode and ACP.
mossyfield/ST-jeved
A SillyTavern extension that has Jev read each chat message and answer rules you write, so a matched rule can add a prompt line, reroll a reply, or run an STscript.
ToolLaya vs Jev: AI vs AI Arena
Laya, running locally, and Jev, over TypeSafe's hosted API, face off in a snake race and a Mortal-Kombat-style fight, both answering the same typed questions on the same input; from a Prompt Engineer 48 video.
ProjectReal-time control
DanRWilloughby/snifftest
A prose linter that flags signs of AI-generated writing, combining zero-dependency countable rules with one judgment model call.
touchpress
A mobile end to end testing library built on the AI SDK and agent-device, now supporting Jev alongside other models. In one test run Jev finished in 29 seconds for $0.003, versus 37 seconds and $0.07 for Haiku 4.5.

Zaious/jev-capability-atlas
An independent, evidence-based map of where Jev's calibrated-decision claim holds up and where it breaks down, built from real API-call receipts rather than a leaderboard.
Article
shaharia-lab/jev-cli
A command-line tool for Jev: ask yes/no, multiple-choice or rubric questions about any text and get calibrated probabilities back as shell exit codes, JSON, or MCP tools.
compozy/yoshi
Local context-pruning proxy for Claude Code and Codex. Jev judges which conversation history is still needed above a configurable size gate, and Yoshi applies the validated omissions before forwarding to Anthropic or OpenAI; the author calls it a proof of concept headed into CompozyOS.
Tool
colliber/duckdb-jev
A DuckDB extension that returns Jev's typed answers as native SQL types, so a query can call Jev directly.
Tooltsai-sc (Jev plays StarCraft)
Harness that lets Jev control the original StarCraft shareware through synthetic keyboard and mouse input, recording action probabilities for each decision.
ProjectReal-time controlTev1 (Together AI): Jev-like classifier on Qwen3.5 4B
Data recipe and scripts to fine-tune a Jev-style classifier on Qwen3.5 4B from 37,840 examples for about $17. Together also serves the result, Tev1-4B-experimental, at $0.042 per million input tokens, and a step-by-step tutorial is on X.

Tool
0xBakeer/arbiter
Serves typed-decision models, including Laya or your own, behind a Jev-compatible API on NVIDIA GPUs or Apple Silicon, with coding-agent integrations.
Tooljomatsu/pi-jev-auto-mode
Auto mode for the Pi coding agent, which has no permission system of its own. A deterministic layer handles hard denies and your allow and deny patterns, then Jev judges the bash, write and edit calls it escalates and fails closed when it cannot decide. Thresholds come from recorded real-API calibration.
jev-on-a-laptop
Unofficial study reproducing Jev-style parallel constrained decoding on stock 1.5B-8B models on an Apple Silicon laptop. Prefills context once, broadcasts the KV cache across one batch row per schema field and evaluates all fields in a single forward pass.
AlternativeStructured extraction
luantak/is-malicious
A CLI that scans a codebase's source, config, build and CI files with Jev for hidden or data-stealing behavior, pointing to suspicious files and lines as a second opinion before running unfamiliar code.
ToolLLM guardrailsblakestone-x/jev-mcp
Python MCP server exposing Jev as classify, score, check, match and screen tools, with a confidence value on every answer. Ships registration steps for Claude Code, Codex and Cursor that keep the API key out of tool arguments.
AkashPriyadarshii/jev-superpowers
A skills framework for AI coding agents that adds Jev-based gates and vetting to the workflow.
Toolkeeltrace/hermes-nerve
An asynchronous Jev integration for Hermes Agent that supervises turn admission, tool-call gating and context curation in the background, using up to sixteen typed choice, score and noul questions per call.
typesafe-snake
Snake auto-played by Jev: one Choice per game tick, with legal moves and board facts computed in code before the call.
ProjectReal-time control
shiftynick/jev-axi
Agent-ergonomic CLI for Jev with pick, rate, check, rank, triage and guard subcommands, meant for agents offloading snap judgments from the shell.
TypeSafe AI Playground (jev.works)
Community playground for Jev with around 110 use cases, games, dilemmas and model challenges. Supports editable prompts, A/B comparisons, conversation routing, document field extraction and code-policy inspection in a Next.js interface. Hosted at jev.works.
Ray-Hughes/jevalyn
A Rails-native wrapper around TypeSafe's Jev API that puts typed, calibrated decisions directly in a Rails app's control flow.
Toolkieranklaassen/ruby_llm-typesafe
TypeSafe structured-output provider for RubyLLM 2, wiring Jev into the RubyLLM provider interface.
NiazMorshed2007/jcr

Brainwires/jevwire
A Jev decision layer for agents, shipped as an MCP server, an embeddable DecisionModel library, and an escalate-only Claude Code plugin.
Tool
Laya MPS
A local server running Laya's typed-decisions checkpoint on a Mac's GPU through PyTorch MPS, with a Pong demo and a memory-versus-latency tradeoff reaching about 32ms median decisions at 2.1GiB RAM on an M5 Pro.
GodsBoy/jev-agent-skill-router
Routes agent skill selection through typed, confidence-aware Jev questions so a weak match is sent for review instead of guessed. On 72 synthetic requests it routed 68 correctly (94.4%) against 51 (70.8%) for a lexical baseline, at a median 1,287 ms; the author labels the results exploratory.
unicodeveloper/jevocks
A stock decision terminal, self-titled Jevinik: it pulls live market evidence through Valyu and uses Jev to estimate the probability a stock trades higher in 30 days, without calling a general-purpose LLM.
ProjectComposite scoring
rlaope/jeval
Measures what a Jev classifier's confidence score is actually worth against real outcomes, and sets the threshold for handing a decision to a human based on what a mistake costs.
abhishek085/open-spark-jev
Open-source, local decision models inspired by Jev and System One, built on Qwen3 and sized for an NVIDIA DGX Spark.
Alternativelaya_ex
A native Elixir runtime for Laya built on Nx and Bumblebee, downloading the official checkpoint on first load and answering typed choice and noul questions in-process.
Toolainame/swift-typesafe
Unofficial Swift 6.4 SDK for TypeSafe that follows the Python SDK's 0.6.0 API, with macro-based question sets for Choice, Noul and Score. Supports macOS 26+, iOS 26+, tvOS, watchOS, visionOS and Linux, and tracks the upstream version it mirrors.
Toolromaluev/jev-ego
TypeScript browser agent for ego lite with no Chrome, Playwright or browser harness. Each observation produces a numbered element table, and one TypeSafe request picks the operation and the target element. A coding agent can drive the page itself or ask Jev for ranked directions.
Laya Drift
An OpenCode plugin that embeds the running session state with Laya and scores how far it has drifted from the calibrated plan using weighted Jensen-Shannon divergence, shown live as a sidebar score.
pi-jev-triage
Pi coding-agent extension that splits large tool results into blocks, has Jev score whether the agent will need each one, and hides low-scoring blocks behind a stub recallable with pi_jev_recall.

Two AI models play real-time Tetris against each other: Jev faces Claude Haiku, Gemini Flash, or an open-weight typed-decision model, with the same piece sequence and clock for both sides.
ProjectReal-time control
tyler-dot-earth/patdown
A fuzzy linter that uses Jev to check code against rules and conventions written in plain language, shipped as a CLI, a GitHub Action and a pi package.
webdevcody/jevs-fly
A Three.js first-person flight game where a glowing fly chases goblins in a garden; Jev chooses its heading and dive about five times per second.
ProjectReal-time control
AntonioCoppe/jev-harness
TypeScript library that wraps Jev choice, score and noul answers in the parts production needs: a policy, a confidence gate, shadow mode, reusable recipes and an offline eval CLI. On the same row-filter job it measured 1.3 s against 48.9 s for the Claude Code CLI.
mejiasd3v/pi-jev-router
Pi extension that lets Jev choose a model and reasoning effort through Vercel AI Gateway, then keeps both pinned for the session. Generation still runs on your existing Pi providers and credentials.
