Jev Repos & SDKs#community#catalog-import#madewithjev
Communitytc3oliver/laya-applePython
Laya Goish
17GitHub stars
Laya GGUF inference and an HTTP server written in Goish Rust: one Linux binary runs upstream Laya or OpenThai-SystemOne on your CPU and serves typed choose, score and check decisions over HTTP, the CLI or a JSON-lines process.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communitycogentica-ai/laya-goishRust
JevTuner
15GitHub stars
A tuner that trains language models to answer closed-set decisions with a complete probability distribution in one forward pass, using a tokenized multi-class Brier loss so only the correct choice is needed to train.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communityliushiliushi/jevtunerPython
Parallel Constrained Decoding
15GitHub stars
A Java and Python implementation of parallel constrained decoding: fill a whole JSON schema of booleans and enums in two forward passes, with calibrated confidence per field and output that is schema-valid by construction.

Jev Repos & SDKs#community#catalog-import#cobanov
Communityalgorythm-canada/openjevswiftSwift
Jev for Elixir
10GitHub stars
A small, idiomatic Elixir client for Jev: Jev.ask?/2 returns a real boolean, choose/3 picks among supplied options, score/3 rates ordered levels, and analyze/3 sends several typed questions in one provider request.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communityelue-dev/jev_elixirElixir
laya-candle
10GitHub stars
A pure-Rust port of Laya that answers typed questions — choice, score or yes/no — about any text in one batched forward pass, loading checkpoints from the Hugging Face Hub via candle and returning calibrated labels, scores and probabilities with no Python.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communitytrystan-sa/laya-candleRust
JevOps
8GitHub stars
A TypeSafe/Jev kernel split out of Lean Refactor Arena: it acts as a gate rather than a proof authority, with choice/score/noul projectors, caches and rankers, and Lean candidates that only a consuming Lean/Lake verifier can admit.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityendomorphosis/jevopsPython
tool-prune
8GitHub stars
A zero-dependency tool selector that narrows a large pool of agent tools to the relevant few before the LLM call, running offline with TurboQuant or on TypeSafe Jev when a TYPESAFE_API_KEY is set.

JevRanker
6GitHub stars
Plugs Jev-style decision models into published rerankers as a fast primitive: one forward pass over k candidates, zero decoded tokens. On T2Ranking it reports up to 22x faster matches than a generative listwise reranker at 2.9x the nDCG@10.
Jev Repos & SDKs#community#catalog-import#yibie
Communityhgqimo/jevrankerPython
jev-agent-tools
6GitHub stars
A multi-provider Jev transport layer with fail-closed validation, used by jkudish/jev-browser and jkudish/jev-mcp. One ask() call picks a carrier, sends typed questions and validates answers instead of throwing a verdict.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityjkudish/jev-agent-toolsJavaScript
OpenJev
6GitHub stars
Open reimplementation of the Jev decision-model idea: masked-logit softmax turns any small local LLM or OpenAI-compatible API into a type-safe decision engine with raw probabilities. Also ships a WeChat/QQ/Telegram crush radar with a verdict and next-move advice.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitylookski/openjevPython
goodall
5GitHub stars
Small Go library for tool-using AI programs: the agentic loop runs until the model finishes or a budget stops it, with Anthropic and OpenRouter providers, tool schemas inferred from Go types, and an optional chat package for threads, SSE and NDJSON.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitybensyverson/goodallGo
jev-php
5GitHub stars
A small PHP 8.1 library, extracted from LLPhant, giving typed value objects for Jev's Noul, Choice and Score answers, with probabilities and token usage. Unofficial and community-built; you supply a TypeSafe API key, or point it at Laya.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityf-lombardo/jev-phpPHP
Laya Go
5GitHub stars
The Go server, agent CLI and MCP for Laya - open horizontal System 1 decision models that score structured features and return ranked pattern probabilities instead of text. It ships a JEV compatibility API and a migration guide.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communityneko233-com/laya-goGo
Questions
5GitHub stars
Typed semantic decisions for TypeScript: ask Zod 4 or native question batches about your data and get validated answers through async/await or Web Streams, with confidence gates, retries, replay and observability. Jev runs via TypeSafe AI or Vercel evaluation.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitynitoba/questionsTypeScript
jevr
5GitHub stars
A native R client for Jev and TypeSafe System One: send a state plus typed questions and get structured answers back in R. Supports jev_choice, jev_score and jev_noul questions, several questions per evaluation, and jev_map over many states.
Jev Repos & SDKs#community#catalog-import#cobanov
Communitysimxnherrera/jevrR
jevlang
5GitHub stars
Python with a smart if: .jev files add the ~ question operator and jev/case blocks that Jev answers with a number or a label, never text. Files are rewritten to plain Python at import time; every ~ is one paid TypeSafe API call.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitysumanmichael/jevlangPython
jevsql
4GitHub stars
A weekend experiment in text-to-SQL where the model never writes SQL: Jev fills typed slots — intent, table, state, county, number — each with a calibrated confidence, and Python code assembles the answers into a parameterized SELECT.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitysarathi-aiml/jevsqlPython
jevtok-ts
3GitHub stars
Offline Jev token counting and request accounting for Node.js and Next.js: an MIT TypeScript port of jevtok that matches the reconstructed encoder for jev-1.13-20260917 and ships its vocabulary inside the package — no keys, network calls or dependencies.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityaarzhaev/jevtok-tsTypeScript
hfjev
3GitHub stars
A Python and JavaScript package that loads any Hugging Face dataset, auto-adapts evaluation rubrics to the domain, and classifies every row through a single parallel Jev call with calibrated probabilities, plus a CLI and an interactive studio for uploads and export.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityhemanth/hfjevTypeScript
jevtrader
3GitHub stars
A Rust project described as a high-frequency trader that uses Jev as its decision maker. The repository has no README, license or usage documentation, so the entry is grounded on the GitHub description and list metadata alone.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitynachom3/jevtraderRust
jev-browser-local
3GitHub stars
A fork and bridge that runs jkudish/jev-browser fully locally: a local Jev-style engine built on parallel-decisions replaces the hosted API, with Qwen2.5-1.5B-Instruct picking each browser step and a 0.5B model typing search queries, measured on an RTX 2060 SUPER.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityrorshopping/jev-browser-localPython
typesafe-go
2GitHub stars
A Go client for the TypeSafe System One API with zero dependencies outside the standard library: typed Noul, Choice and Score questions whose answers are read back through the handles that asked them.
Jev Repos & SDKs#community#catalog-import#logicrw
Community2389-research/typesafe-goGo
Prosodia — an audio Jev
2GitHub stars
An audio-native decision model shaped like Jev: audio is encoded once, several typed questions branch over that single encoding, and answers come back as calibrated probability distributions — no transcript, no ASR, the Whisper decoder never runs.
Jev Repos & SDKs#community#catalog-import#cobanov
Communityalperiox/audio-jevlikePython
local-jev
2GitHub stars
A 100% offline, zero-cost Rust drop-in for the TypeSafe Jev System One API: one native binary serves Choice, Score, Noul and Route decisions on CPU in under 18 ms with no API keys, cloud egress or rate limits.
Jev Repos & SDKs#community#catalog-import#madewithjev
Communityronitgupta138/local-jevRust
jev-msw
2GitHub stars
Contract-aware MSW handlers for the official @typesafe-ai/sdk: mock Jev choices, Nouls and scores in tests without API calls, credentials, latency or credits, while the real SDK parsing and retry logic still runs.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityroyalpinto007/jev-mswTypeScript
jev_dart
2GitHub stars
Pure Dart client for the TypeSafe System One API, usable from a CLI, a server or a Flutter app. The request path avoids extra copies and reuses HTTP/2 connections, and no comparative benchmarks are published.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitysolido/jev_dartDart
Hunch
1GitHub stars
Probabilistic control flow for TypeScript: Hunch asks a System One model such as Jev yes/no questions, thresholded booleans, picks and ratings, and returns typed answers you can branch on in ordinary code.
Jev Repos & SDKs#community#catalog-import#cobanov
Communitycarldaws/hunch-tsTypeScript
Fake / Real (made with Jev)
1GitHub stars
The production code behind fake-real.live, published so its Jev integration can be read and run: Firecrawl fetches a page, Gemini extracts up to five atomic claims, Tavily searches, and Jev decides which sources to read and whether each claim is supported, contradicted or unknown.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitydansidanutz/fake-real-jevJavaScript
fuzzy-jev
1GitHub stars
A CLI, Rust library and Python package that asks Jev typed Noul, Choice and Score questions through OpenRouter, then turns the probabilities into decisions with fuzzy rules — AND, OR, NOT and hedges into a support score per decision, or a crisp amount — and can draw the rule base as SVG.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitydsaad68/fuzzy-jevRust
typesafe-jev (Ruby)
1GitHub stars
A zero-dependency Ruby client for Jev: ask typed Noul, Choice and Score questions about your application state and get frozen, typed answers with probabilities, confidence and token usage. Pure Net::HTTP and JSON, so it fits plain Ruby and Rails alike.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitydtheofr/typesafe-jev-rubyRuby
jevish
2GitHub stars
Zero-dependency JavaScript library for semantic pattern matching and zero-shot judgment: the in-tree engine behaves like Jev in local CPU cache under 0.05 ms and speculatively escalates ambiguous inputs to cloud Jev when cascade is enabled.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityhemanth/jevishJavaScript
traffic-guard
1GitHub stars
Zero-dependency reverse-proxy traffic classifier and bot mitigator shipped as Node.js and Python packages. The in-tree engine decides in tens of microseconds, and setting TYPESAFE_API_KEY elevates the gate to jev-latest for five parallel typed questions.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityhemanth/traffic-guardPython
jev-route (huzeyfe07)
1GitHub stars
Async, typed intent and tool routing library for Python agents: register your own callables with @router.intent and @router.tool, let Jev decide which capability handles an input, and let a confidence gate stop weak or invented decisions.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityhuzeyfe07/jev-routePython
jev-is-not-odd
1GitHub stars
Deliberately absurd npm utility that uses TypeSafe's Jev model through the Vercel AI SDK to decide probabilistically whether a number is not odd (or not even). It needs a Vercel AI Gateway key in AI_GATEWAY_API_KEY.
Jev Repos & SDKs#community#catalog-import#logicrw
Communityitzsupra13/jev-is-not-oddJavaScript
TypeSafe Swift SDK
1GitHub stars
A Swift-native SDK for the TypeSafe System One API, ported from the JS and Python SDKs: Swift Package Manager, Swift 6 concurrency and URLSession, with Choice, Noul and Score questions and strict response validation.

Communitymarandaneto/typesafe-sdk-swiftSwift
xjevboost
1GitHub stars
Classify tabular data with Jev, Laya or OpenJev without putting your whole labeled dataset into context: a learned tree of small views asks for more rows and columns only when they help, then stops.
