An AI API server that abstracts multiple models and providers behind one layer, for local use with Ollama or LM Studio or in the cloud via OpenRouter, OpenAI, Anthropic or Google. It now supports Jev.
A local, open-weight port of browser-use's jev-ultrafast agent that swaps Jev's hosted decisions for Laya running on Apple Silicon through MLX, while keeping the original hosted Jev policy as a fallback mode.
145 starsDecision latency ~33ms
Extension making Jev the decision layer for the Pi coding agent: a measured tool-call gate plus a jev_ask tool. Judges whether an action is destructive, exfiltrates data or exceeds scope, then blocks or warns on calibrated thresholds.
144 starsGate latency ~300ms
A Claude Code plugin that uses Jev to trim noisy Bash output after a command runs but before the result reaches the main model, once the output passes an estimated token threshold.

Guardrails for the Pi agent built on pi-typesafe. Jev judges irreversible and off-task tool calls, detects stuck loops, checks unverified completion claims and flags low-quality output, steering the agent rather than interrupting the user.
138 starsHolds per 1000 calls 3
A grep that matches lines by meaning instead of regular expressions: Jev scores each line against a plain-language description and the tool applies a threshold, combining meanings with AND, OR and NOT.
134 starsBatch speed <1s/210 lines
An Agent Skill that guides a coding agent through writing and improving programs that call Jev.

A benchmark that has language models play chess against a random-move player and the Komodo Dragon engine, scoring both chess skill and whether the model keeps making legal moves without hallucinating.
Navigates a Neo4j graph one hop at a time: the outgoing relationships of each node become Choice options and Jev returns a distribution over which to follow, with a Noul question about reaching the goal riding in the same call. Top-k over summed log-probabilities makes it a beam search, drawn in an interactive graph.
Rust CLI that hands an agent's live session context to Jev, which compares the available skills and estimates which fit the next step. Ships Claude Code hooks, structured JSON, abstention, a terminal display and local feedback.
Command-line toolkit a coding agent can delegate judgment work to: ranking relevant files, checking a diff against its task and project rules, and triaging test failures or review comments. Each request runs one bounded typed workflow and returns a structured report.

Scores source-file quality by asking Jev a set of yes/no questions, runs the test command you already use, and turns uncovered paths into small queries a coding agent can work through. Scoring costs about a cent per megabyte of source; coverage needs no account, config file or hosted service.
109 starsScoring cost ~1c/MB

Fish-style autosuggestions for zsh ranked by Jev. As you type, the plugin sends your last 100 distinct history entries and asks which one you are most likely completing, then shows the best match in grey with its score for you to accept.
Personal-assistant agent built with Vercel's eve framework and 100 mocked tools, served through OpenRouter. Measures how many steps the agent needs when the LLM picks the tool itself versus when Jev picks it via a 101-option Choice.

Browser agent that indexes the page into candidate actions and has Jev pick one, so it cannot click something that was never on the page, while an LLM plans and reads. Every claim in an answer cites a quote stored verbatim from the page, and Jev checks the claim against its quote.

A Chrome extension and small web app that find sponsor reads in a YouTube video's transcript using Jev, then skip or flag them; needs a TypeSafe key and, for some modes, a Deepgram key.
95 starsTranscript mode under 1 cent/hrListen mode ~$0.46/hr

Laya, running locally on Apple Silicon via MLX, and Jev, over TypeSafe's hosted API, play Chrome's T-Rex game side by side on a shared obstacle course, with response times, survival streaks and crash replays recorded.

A computer-use harness for macOS that reads the screen through the Accessibility API and lets Jev pick the action, with no vision model in the loop.
Small type-safe client for asking questions about your data, powered by Jev. Returns probabilities, choices and scores in a single request, and ships an agent skill that teaches coding agents how to design the questions.

Turns Jev into a chatbot by repeatedly asking it which symbol comes next from an alphabet of options, then sampling from the returned probabilities. An experiment built by describing the sampling strategies to Claude and having it implement them.
Pre-alpha PostgreSQL extension that calls TypeSafe Jev from SQL for Choice, Noul and Score, including a batched function that classifies many distinct rows in one request.
82 starsOne-by-one time 23sBatched time 0.86s
Browser automation where an LLM plans and Jev decides each tactical action, executed through Playwright without feeding page snapshots to the LLM. README reports 40/42 tasks passing and roughly 5x less token context.
82 starsTask accuracy 40/42Checkout time ~14s
A Python evals and guardrails library for agent traces that uses Jev-style decision models instead of an LLM judge, running Jev through TypeSafe or Vercel, or Kev or Laya locally on a Mac. All checks for a trace go out as one request in a few hundred milliseconds.
81 starsVariance vs LLM 92-913x

Puts a live Jev meter on any video: every sentence is scored, every dodge flagged, and the result rendered as a 16:9 edit. The repo reports 99% preset accuracy on a held-out set and about $0.05 for a full debate.

A Claude Code hook that splits large tool results into blocks and asks Jev a yes/no relevance question per block, replacing low-relevance blocks with a short recoverable stub before they enter context.
Chrome extension that finds ad-shaped DOM elements in plain code, then asks Jev whether each candidate is an ad and pops it off the page. Bring your own key and there is no backend, and the author calls it a fun side project rather than a real ad blocker.
Codebase search that finds files matching a natural-language request through repeated Jev-guided passes over a directory tree.
Adds a bounded decision loop to Codex Computer Use: Codex prepares the goal and allowed actions, Jev selects the operation and target in one request, and Computer Use performs the click.

Semantic code search for coding agents: it scans an authorized repository, asks Jev to score all eligible fragments against a plain-English question, and returns the original source excerpts with their paths and line numbers.

Unofficial Home Assistant integration that asks Jev questions about your house and turns each answer into an entity you can automate on. Questions in configuration.yaml become sensors, and four actions answer inside an automation and return a response variable.
Swift 6 bridge that maps Apple Foundation Models @Generable types onto Jev: Bool to noul, enum to choice, and @Guide range to score.
A console whose whole design system is generated at runtime by Jev from a one-sentence brief.
A Python CLI that turns Jev calls into Unix-pipeline predicates, routing, scoring and JSONL filtering with stable exit codes, plus an agent-safety guard recipe for authorization and destructiveness checks.

Local UI and CLI for Instagram, TikTok, and LinkedIn research. At each step Jev picks the next read-only operation from a list built from earlier results, the socai CLI runs it in the user's Chrome, and the captured posts become a cited report.

Uses Jev to pick which of your project's rules apply to a given prompt, so Claude only sees the relevant ones.
Rust and Python dataset sifter that streams Parquet and JSONL rows past Jev typed decisions at 1,500+ records per second, writing passed and rejected rows to disk. Uses speculative fan-out and calibrated post-training rubrics.

A local recruiting workspace built on Browser Use's Jev Ultrafast: Jev chooses which LinkedIn profiles to browse, screens titles, and assesses profiles against a hiring brief, keeping the evidence.
Adds semantic tool routing, skill discovery and typed Choice, Noul and Score judgments to the Pi coding agent. Opt-in modes pick the model per prompt and use Jev to decide which tool history survives compaction.
Experimental Hono router where you describe a request in plain words and Jev decides which description fits the incoming request. The author warns it is not an authorization boundary, and the values of Authorization, Cookie and API key headers are redacted before anything is sent.
An agent plugin and MCP tool that sends a query plus a batch of file paths, URLs or text straight to Jev and returns relevance probabilities, so the calling agent only opens what is worth a closer look.

Pi extension that gives the agent and other extensions one key-managed TypeSafe client. A batched typesafe_evaluate tool hands classify, triage, compare and score judgments to Jev in a single call, and a terminal playground runs requests without touching the model's context.
Real-time Discord moderation bot that runs Jev evaluations over message text and metadata in parallel to catch phishing, spam and social engineering, with a progressive escalation ladder.
