New this week

All projects

531 projects

New projects need 10+ stars to be added. Entries from before that bar stay until they go quiet, so a few small ones are still here — often the only client for their language.

Laya

★ 32k▲ 1.6k

NandhaKishorM/laya

Non-autoregressive decision engine over 100+ languages: three checkpoints and a router that detects the script and dispatches per request. Its benchmarks end with a limits section naming the datasets it does not generalise to and the headline figure that came from a training split.

jev-ultrafast

★ 23k▲ 646

browser-use/jev-ultrafast

Fast browser agent from Browser Use. Jev decides each step and which element to act on; a small model is called only when text needs to be typed. The authors report a full Google Flights search in about 7.1 seconds.

kev

★ 9.0k▲ 509

jaredpalmer/kev

Jev-style decision models from 0.5B to 8B, built as LoRA adapters on Qwen and served behind a Jev-compatible /v1/systemone API.

fast-jev-compaction

★ 7.6k▲ 197

tamaratran/fast-jev-compaction

Claude Code plugin that replaces the compaction summary with Jev decisions. Every tool call and result is scored; stale ones are dropped or truncated, and everything kept stays verbatim.

SemIf

★ 4.8k▲ 91

TheoLeeCJ/SemIf-OpenJev

Jev-style decisions from a frozen 4B model on a single RTX 3090, with a browser demo. Formerly OpenJev.

OpenMuse

★ 4.7k▲ 695

CopilotKit/openmuse

CopilotKit's self-hosted personal agent with its own browser, terminal and files; Jev decides whether a reply becomes a clarification panel, a comparison of options or plain prose, and overrides the agent only when confident. Alpha.

Apps & Browser ExtensionsTypeScriptReviewed

jev-trader

★ 3.0k▲ 148

jarrodwatts/jev-trader

Asks Jev buy or sell on every Monad block and places real post-only limit orders on the Kuru MON-USDC book. Not financial advice.

AnyJev

★ 1.2k▲ 162

nokia-applied-research/AnyJev

decider

★ 1.1k▲ 63

Mapika/decider

A family of System One-style models that never generate text: one forward pass over a state and typed questions returns a probability distribution per question. Ships ten text games and a Super Mario Bros agent where each move is one typed decision over the legal actions.

Pre-registered calibration audits of AI judges, comparing Jev's native probabilities with LLMs' verbalised confidence and vote shares, caveats stated beside every result.

JevBench/jevbench

Tests whether a decision model's probabilities fit together, using 50 laws of probability and choice and no gold labels. Unrelated to the JevBench above.

x402check

★ 11▲ 1

caiovicentino/jev-risk-check-provider

Pre-payment risk-check provider for x402 agents and wallets: sanctions lists, phishing feeds and transaction simulation, plus Jev questions over what the agent acted on to catch injected instructions. Signed verdicts.

FinanceTypeScript

Kludex/pydantic-ai-go

Go port of PydanticAI's agent loop, tools and structured output, with a TypeSafe Jev model provider and a generic System One provider alongside the LLM ones.

mblode/taste-lint

Design review on every commit: 28 blocking checks and more advisory ones, with the fuzzy ones — vague errors, bare confirm labels, empty states — sent to Jev through Vercel's AI Gateway as review notes.

Yardsort

★ 10

joaoh82/yardsort

Desktop app for running coding agents in parallel, each in its own git worktree, with optional Jev judgements on each change. GPL-3.0.

sensored

★ 10

atomicpages/sensored

Streaming PII redaction for TypeScript with regex and NER detectors, and an opt-in step where Jev confirms a detection before it is redacted.

Jevia

★ 10

assistant-ui/jevia

Local-first, outcome-based router for coding harnesses: it picks a capability tier per task, applies your safety policy, and learns from recorded execution history.

robertn702/opencode-jev-router

OpenCode plugin that asks Jev how much reasoning each step needs, so one model handles quick edits and hard debugging; runs in-process or as a Responses API proxy.

Model RoutingTypeScriptArchived

jev-pilot

★ 10

Akramovic1/jev-pilot

Claude Code plugin that asks Jev before each turn for the reasoning effort, subagent model and skill to use, with a decision log, tuning suggestions and an animated pet that says what Jev decided.

Model RoutingTypeScript

jeq

★ 10

cristianoliveira/jeq

Typed questions in a shell pipeline, for scripts and agents that want an answer without the boilerplate.

tontoko/jev-browser

One core behind a typed SDK, a persistent CLI and an MCP server: native Playwright operations and assertions need no key, and only the natural-language paths call Jev. Japanese.

Jev RAG

★ 10

aifabrice/jev-rag

Local knowledge search with seven selectable pipelines, BM25 plus Jev reranking by default, streaming cited answers over your own document folder.

MarissaFamularo/citation-verifier

Checks whether each cited paper supports the sentence citing it: Claude finds the quote, Jev judges support with a probability you can read as a reliability mark. Hosted version available.

LuliYanng/LiquidType

Liquid Glass style voice typing for macOS 26 with an optional Jev fast path that types clean short sentences immediately instead of waiting for LLM cleanup.

jevcal

★ 10

abhixhek/jevcal

Picks the confidence threshold that meets your accuracy target on your own data, and fails CI when a model update breaks it.

ruling

★ 10

bradAGI/ruling

Turns any open chat model into a local decision engine: a state and typed questions in, a probability for every option out, no text generated. Not affiliated with TypeSafe.

Algorythm-Canada/OpenJevSwift

Native Swift implementation of the OpenJev typed-decision server: yes/no, choice and score answers on Apple platforms, with a triage demo app.

Carve-Jev

★ 10

FuturixAI-and-Quantum-Works/carve-jev

Open Jev-like model family that reads one-token decisions from Qwen3.8 under vLLM and serves a TypeSafe-shaped API, with one-command setup.

reachjalil/jev-tree

Recursive Choice over a taxonomy, for picking among more options than a single Choice question allows.

Libraries & IntegrationsTypeScriptReviewed

zod-jev

★ 8

jomatsu/zod-jev

Adds Jev semantic checks to Zod 4 schemas. Zod validates the shape; Jev validates the meaning.

Libraries & IntegrationsTypeScriptReviewed

valentynkit/jev.nvim

Neovim plugin that splits the buffer into functions with Treesitter, has Jev score each one against a plain-language question, and lists the answers in the quickfix window ranked by probability.

valentynkit/jev-plays-pokemon-red

Pokemon Red on PyBoy where code owns the route and the arithmetic and Jev only picks at branches, logging a Brier-scored faint prediction against RAM state on every battle turn.

valentynkit/jev-skip

Browser extension that reads the caption track and paints a sponsor-probability overlay on the YouTube seek bar before the intro ends, with no crowd database. The author reports catching 77% of SponsorBlock's sponsor seconds across 23 videos at $0.0008 per video.

Apps & Browser ExtensionsTypeScriptReviewed

andrelandgraf/safer-with-jev

Neon Function proxy for the Neon AI Gateway. Jev classifies each request and routes it to the right downstream model.

Model RoutingTypeScriptReviewed

markjaquith/typesafe-ai-playground

Rust CLI of Jev experiments, including PHI detection, code-comment review, live tone analysis, and occupation and industry classification.

Command-Line ToolsRustReviewed

noelzappy/tripwire

Runs seven checks on every LLM response in one Jev call, as AI SDK middleware or an OpenAI-compatible proxy.

Guardrails & SafetyTypeScriptReviewed

iamvatsalpatel/tiershift

Sends each LLM request to the cheapest model tier that can handle it and escalates on evidence.

Model RoutingTypeScriptReviewed

aoprisan/jev-ts-repl

Terminal REPL for shaping System One requests before writing code. Simulates answers when no API key is set.

Command-Line ToolsTypeScriptReviewed

Janus

FirasSX914/Janus

Measures Jev's calibration and confidence-based routing on Banking77 and Web of Science.

m0rphtail/triagedy

Security alert triage as a Unix filter: JSONL alerts in, typed decisions out.

Command-Line ToolsRustReviewed

ably-labs/jev-pong

Pong where the ball moves one step per model decision, pitting Jev against chat LLMs.

Games & Real-Time DemosTypeScriptReviewed

rashedInt32/jev-gates

Seven calibrated gates for Claude Code (rules, scope, intent, done, claims, proof, and commit honesty) that escalate but never approve.
