Jev Repos & SDKs#community#python#home-assistant
55GitHub stars
Qwen3.5-0.8B fine-tuned to play ten classic browser games from raw pixels: one frame in, one forward pass, one move out in 43 ms on an H200. Public weights and a browser demo make it an open, vision-only take on Jev-shaped game decisions.
Jev Repos & SDKs#community#javascript#games
52GitHub stars
Experimental Hono router that matches an incoming HTTP request to a plain-language route description: one yes/no Jev question per description is evaluated in a single call, and the first registered route above the threshold wins.
Jev Repos & SDKs#community#typescript#routing
Unofficial LlamaIndex reranker and router built on the official Python SDK: JevRerank scores retrieved passages and JevSingleSelector chooses which tool handles a query.
Jev Repos & SDKs#community#python#sdk

Jev Repos & SDKs#community#typescript#routing
5GitHub stars
A Scala 3 and ZIO HTTP client for TypeSafe's Jev System One API: ask typed Noul, Choice, and Score questions in one round-trip via a NamedTuple and get answers shaped exactly like the questions.
Jev Repos & SDKs#community#scala#sdk

Jev Repos & SDKs#community#python#evaluation
2GitHub stars
An async Python client for Jev with typed Noul, Choice, and Score helpers: questions batch into one request, and callers get probabilities, choices, and weighted scores instead of text to parse.
Jev Repos & SDKs#community#python#sdk
18GitHub stars
A RubyLLM 2 provider that adds Jev through structured output: build Noul, Choice, and Score questions with a schema builder, pass them to chat.with_schema, and read typed answers from response.parsed.

A TypeScript library that wraps Jev answers in a policy, a confidence gate, shadow mode, reusable recipes, and an offline eval CLI, so structured decisions can drive actions an application ships.
Jev Repos & SDKs#community#typescript#agents
14GitHub stars
An experimental TypeScript harness that connects evidence to Jev judgments, permitted actions, and verified outcomes, with pluggable data sources and tools, local JSONL traces, and zero runtime dependencies.
Jev Repos & SDKs#community#typescript#agents

Jev Repos & SDKs#community#typescript#mcp
917GitHub stars
An open, non-autoregressive System One model with published weights and a TypeSafe-compatible /v1/systemone API; the 395M-parameter OptionMarker checkpoint scores discrete and ordinal questions locally.
