OpenJev: open-source, local alternative to Jev. System-One decision models: typed questions in, calibrated probabilities out; general decisions and browser-agent steps.

OpenSource Jev

Typed-decision models (noul / choice / score) trained by a self-improving loop of AI agents — checkpoints, the code that produced them, and every version that failed.

Open infrastructure for training, evaluating, and deploying System 1 decision models across language and multimodal backbones.

Turn any off-the-shelf LLM into a Jev -like decision layer

A nano replica of Jev: parallel decisions, dynamic candidates, and an end-to-end training pipeline.

Jev-like family of decision models built on top of Qwen3.5/3.8 you can train and run on your own

Open replica of TypeSafe's Jev: typed calibrated decisions in one forward pass, on Gemma 4 E2B / Gemma 3 270M (Modal)

Small System One decision models (17M–400M) for Yes/No, Choice, Score, and reranking. Training toolkit, Python inference, and ONNX support for Node.js and browsers.
