## FAQs

What is Jev?

Jev is TypeSafe's low-cost AI model built to make decisions instead of generating text. It returns simple answers like yes or no, choices, scores, or lists of options, making it much cheaper to run than traditional text-generating models. Your app can use these answers to make decisions for users, with confidence scores to know when to act and when to ask for confirmation.
