Unlike a typical LLM, Jev doesn't take open-ended prompts and return text. Instead, you feed it context plus a set of questions and candidate answers, and it returns probabilities for each — fast and cheap. The author illustrates with an e-commerce example: an agent in the support workflow uses Jev to score inquiries and make judgment calls at scale.
