openjev

What it does

This is a separate open-weight model inspired by Jev, not TypeSafe’s Jev.

How you can use it

Start by writing out a clear set of guidelines, such as your store refund rules. Gather a few realistic customer situations to test. Your developer can set up the open model files so your app can evaluate whether each case follows your rules.

Keep in mind that trick instructions inside customer text can easily fool this model. Never rely on it alone to catch dangerous requests or protect your software. Have your developer keep strict security checks written directly in ordinary code.
