Jev is a model built to make focused judgments. You give it information to consider and define the answers it may choose from. Jev returns a structured answer your code can use, along with probabilities that show how uncertain the answer is.
TypeSafe AI calls Jev a System One model, meaning it is designed for quick decisions rather than long reasoning or open-ended writing. Your code stays in control of the workflow while Jev handles one narrow judgment at a time.
