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

Luce: a recipe for calibrated decision models — a sentence about your task in, a small model that answers typed questions with honest probabilities out (init → synth → train → eval → serve)

Fast zero-shot and few-shot LLM routing powered by Jev.

turn any llama-server into a jev system one endpoint

High-throughput, robust native DuckDB extension for batched and streaming TypeSafe/Jev classification, scoring, and semantic predicates from SQL.

Juste un LLM

A TypeSafe Jev-compatible HTTP server (POST /v1/systemone)

An instrumented 2048 web lab where every move is a Jev (TypeSafe AI System One) Choice, with no heuristic fallback | 用 Jev 决策模型驱动每一步的 2048 网页实验台，概率、置信度、延迟与成本全部摊开可见，且刻意不做启发式兜底

Score how well a resume matches a job description using Jev (TypeSafe AI). Next.js app that returns typed, explainable match scores instead of generated text.

React components that resolve which component to render, how to order a list, and whether to show an affordance — from calibrated judgments returned by TypeSafe's Jev.

Type anything. Get related emojis scored 0–3 with Jev.

R client for the TypeSafe Jev System One API

Grok Build with TypeSafe Jev routing tool selection once per turn: 22 to 40% cheaper on the same tasks

A Stop hook for Claude Code and Codex, for the turn that ends half-done — nothing done, an announced action never carried out, a promise to watch CI with nothing running — or in the wrong language. Every judgement is made by TypeSafe Jev.

Community-maintained Go SDK for the TypeSafe AI System One evaluation API, with typed questions, fluent builders, retries, and examples.

cuda-Jev — a CUDA-native Jev System One decision inference engine. Jev compatible API, examples, and reproducible benchmarks.

Typed decisions for AI agents as an MCP tool: yes/no probability (noul), choice, and score in one fast request. Backed by the TypeSafe System One model.

Open source JEV

Conversation agent based on Laya, a multilingual, non-autoregressive System 1 decision model.

Ask Jev over columns of data: closed-set questions, cached and joined back.

Don't burn your model's context on a search flood — pipe it in and read above the cut line: one calibrated number per candidate, ~30 rows whether the pool is 40 or 4,000. It doesn't search; it decides what each hit is.

Coding-agent tools on TypeSafe's Jev, measured in public. review-router: caught 13 of 13 CVE fixes a filename rule sent to a quick review. jev-gate: a strict second lock, 0 of 12 dangerous test commands ran where Claude Code's auto mode let 8 run.
