Jev-powered: New to synthetic survey respondents? [Start here](#new-to-this-start-here). For the raw runs, the scored reports and the code, see [where to go](#where-to-go).

Kotlin Multiplatform client for Jev that returns your own enum/sealed types instead of string keys.

MCP relay that adds use_jev to every server: Jev picks the tool calls, the calling model writes the values Jev cannot choose, the relay executes. Built on jev-dev-kit.

Browser use & computer use for coding agents, powered by TypeSafe Jev: calibrated judgments from a System One model, control loop in code. ego lite / Chrome / Safari · CLI + MCP

Confidence-gated incident routing with TypeSafe Jev

Jev-powered: Use it to test a memory policy before letting it decide what an agent keeps. The lab includes editable cases, a reusable JavaScript entry point, and reports that retain both successful ju

A toolkit, knowledge base, web cockpit, and reference implementation for building AI applications with **Jev (TypeSafe System One)** via **OpenRouter Alpha Decisions** and **TypeSafe Direct API**.

1. Open any website. 2. Click the Jev icon. The side panel opens on **Drive**. 3. Type a goal, e.g. *Search Wikipedia for "espresso" and open the article*, and press **Run**.

Speed and accuracy benchmark: TypeSafe's Jev API vs the local Laya MLX typed-decision model on synthetic tasks

Jev-powered: On the bundled sample (`examples/sample.log`, 200 lines):

Open lab: Jev (TypeSafe System One) routing in front of Claude Code - measured bugs, patch, and a hard fallback with alerts

Unlike generative writing assistants that flatter drafts, jev-writer enforces strict statistical safeguards: an observational power gate, date-confound controls, and Benjamini-Hochberg false-discovery

Millisecond-class test-failure triage for coding agents: RETRY / FIX_CODE / FIX_ENV, powered by TypeSafe Jev.

Vars live in `wrangler.jsonc`: `JEV_BASE_URL` / `JEV_MODEL` (gateway), `TYPESAFE_BASE_URL` / `TYPESAFE_MODEL` (direct fallback), `TURNSTILE_SITEKEY`, `TURNSTILE_HOSTNAMES`, `JEV_DISABLED` (kill switch

Laya vs Jev: local MLX and hosted AI decisions playing T-Rex side by side, with live metrics and replay recording

Pre-registered benchmark: can a 2B local model (Gemma 4 E2B) answer web questions without making things up when a decision model (TypeSafe Jev) makes every call? SearXNG for search, MemPalace for verb

jevkit: fast typed decisions for agents. CLI and MCP tools (route, triage, guard, grep, rank, compact, judge) on TypeSafe Jev. Zero dependencies.

Ruby client for Jev, TypeSafe's System One model: typed questions, probabilistic answers. Zero runtime dependencies.

Claude Code & Codex skills powered by Jev, TypeSafe's System One model. 256 calibrated judgements for $0.0005 in 0.72s — 360x cheaper than Claude Opus 5. Includes the first published Jev calibration c

A probabilistic, AI-powered utility to determine if a number is not odd (or not even) using TypeSafe's Jev model and the Vercel AI SDK.

Probabilities and model versions move. A raw `0.94` is not a release decision. jevcheck records a **production contract** (baseline model + fixtures + expected answers) and evals a candidate against t

TypeSafe Jev hooks for Claude Code, Codex and pi: per-turn skill suggestion and subagent model routing

A Windows companion reply assistant that captures WeChat Windows 4.x windows with local offline OCR, uses Jev to judge intent and generate three candidate replies, and fills the chosen text into the W
