Education and guides with decision models

Educational code where a local LLM voices a game NPC and Jev classifies player messages and checks every line for spoilers.

Web app for yes/no life decisions: ask Jev for a probability of yes, flip a fair coin, or both, inspired by a coin-toss study.

Playbook for using Jev as a cheap gate before expensive agent steps: confidence policy, question recipes, a skill and a router.

Jev-compatible open System One engine with a Claude Code-style terminal REPL showing live probabilities, plus an experiment harness.

Localhost teaching aid that uses Jev to estimate where instructional text asks readers to hold too many ideas at once.

Small one-file Pydantic AI examples where Jev guards prompts, gates shell commands, judges evals and plays Flappy Bird.

Browser studio and templates for trying Jev as a System 1 reflex gate in front of frontier LLMs, with code exporters.

Interactive web workbench for exploring and benchmarking Jev's Choice, Noul and Score via OpenRouter, with threshold transfer curves.

Worked Jev examples for ticket triage and reranking, runnable through OpenRouter without an early-access key, with offline tests.

Data-incident router and use-case guide: registry facts first, then Jev Choice, Score and Noul with confidence-gated human review.

Deno Jupyter notebooks teaching TypeSafe System One from core concepts through patterns and cookbooks.

Educational email agent where Jev picks each message's label, reply need and family flag before drafting.

33-chapter Chinese tutorial on agentic RL and GRPO, including a chapter on when Jev-style external decision models beat training with RL.

Instruction dataset of 119 rows compiled from TypeSafe's public Jev documentation, split by Choice, Noul and Score.

Bilingual research report on what Jev is, how its claims compare with independent evidence, and the open-source alternatives.

Independent field guide to Jev 1.13.0 behaviour across 11,621 requests: framing sensitivity, Snake and 3D city driving experiments.

34-page paper and kit on typed decision systems for agent workflows, separating observation, judgement, policy, action and verification.

Independent 52-page Chinese report on Jev that checks vendor claims and reproduces 50 Chinese tests, with traceable data.

Korean study notes and TypeScript mock-ups of Jev concepts, with a local Laya versus GPT-5 comparison and a calibration toolkit.

From-first-principles PyTorch reconstruction of a Jev-like architecture with typed noul, choice and score heads; random weights only.

Tic-tac-toe teaching project comparing Jev Choice, Score and Noul designs across three levels of state detail.

Long-form analysis of what Jev is, why it is fast, how much of the hype holds up, and how hard it is to reproduce.

Chinese translation of 'Jev Engineering for coding agents', design notes on a harness where Jev makes every per-turn decision.

Japanese research deck, article and source ledger tracking TypeSafe's Jev and System One models over time.

Bilingual single-page essay on Jev's one-step decisions, local tests, failure modes and production limits, with a live demo.

Code examples for Codely's Spanish course on integrating Jev and other System One models into a real application with an LLM fallback.

Short tutorial repository introducing Jev as a System One model and how State, Choice, Score and Noul differ from LLM text generation.

Community Jev cookbook with 10 runnable examples, composition patterns, theory notes and a list of 120+ use cases.

Independent Markdown reference on the Jev API, patterns and limits, written for engineers and coding assistants to build from.

Markdown export of TypeSafe's documentation (110 pages) for feeding to LLMs and agents.
