openjev (zhihz)

How it uses Jev

Open JEV is an independent open-source alternative project inspired by TypeSafe's Jev. It is not affiliated with, sponsored by, or endorsed by TypeSafe. It does not contain Jev's proprietary code, weights, or RLCD implementation. The project name does not imply an official open-source release of Jev.

Highlights

• Accept English or Chinese context, free-form questions, and your own candidate descriptions. No intent registration or question-specific training is required to submit a new quest…
• Return a choice and relative probabilities only over the supplied candidates . No additional answer or abstention option is inserted.
• Support Choice and Binary decisions, multiple questions per request, editable examples, and JSON export.
• Run inference locally, without a paid inference API. The web interface starts in English; switch to 中文 without changing your inputs or results.
• Publish model identity, scoring protocol, evaluation limitations, and a frozen results snapshot.

Getting started

Tested locally on Apple M3, 16 GB unified memory, Python 3.14. Other platforms and dependency combinations have not been validated. The pinned source download is roughly 8 GB; the separate MLX 8-bit copy is roughly 4 GB, so allow additional disk space for both environments and caches.
