open-jev: A tiny TypeScript lib for in-browser, hallucination-free decisions
nicodotdev · x · 2026-09-21
Developer nicodotdev released open-jev, an open-source, tiny TypeScript library built on Transformers.js — described as the open, in-browser version of Jev. You pass a state and any number of typed questions (choice, score, noul), and a single call returns every answer with its probabilities. It's fully typed, so your editor autocompletes the model's answers.
The key selling point: System One style decisions run 100% on-device — text in, typed answers out, one forward pass. Nothing is generated, so it can't hallucinate.
