Automation needs decisions. And when an LLM gets a decision wrong, its confidence is still 99%. In this Lightning Session, Mahesh Yadav decodes Jev, a decision model, from a product perspective: what it is, what it changes, and where to apply it in your own product. What we cover: → How we got here: small language models, large language models, RLHF and RLVR → Why generation models cannot give you a reliable confidence score → RLCD: reinforcement learning with calibrated decisions → The three decision types: choice, score and yes/no → A contract workflow with 8 model calls, 6 of which are decisions → Using confidence thresholds to route uncertain cases to a human → Hands-on labs: the Jev playground, and Jev as a judge for evals → Eval results: Jev vs a frontier LLM vs small LLM judges on speed and cost Key takeaways for AI PMs: → Map your user flow and mark every decision, separate from generation → Set a confidence threshold for each decision. Too high and users get nagged. Too low and errors flow downstream → Break your evals into yes/no questions so a decision model can run them Jev cannot explain, reason or summarize. It is built to make decisions with calibrated confidence, and that is the point.
