open-jev is a browser-focused TypeScript library for typed decisions: one piece of text (the state) plus any number of typed questions go in, and one forward pass returns a calibrated probability distribution per question. Nothing is generated, so an answer is always one of the options you provided. It runs open reproductions of the shape of TypeSafe AI's Jev "System One" model via (Transformers.js). Everything happens on-device: WebGPU when available, WebAssembly otherwise. Models [onnx-community/kev-4b-ONNX](https://huggingface.co/onnx-community/kev-4b-ON
