Jev is TypeSafe AI's System One model. Feed it messy input, get back a structured, calibrated answer your code can branch on — a choice, a score, or a probability. No hallucinations. 70–500ms. Try it live below.
Most intelligence shouldn't have to become a chat window. Jev makes the small, fast, high-volume decisions that used to need brittle rules or an overkill LLM call.
Send a ticket, email, event or document to the right place with a single typed choice and calibrated probabilities.
Turn fuzzy judgments — risk, urgency, quality, lead fit — into an ordered score you can threshold on.
Ask a yes/no noul and get a probability, so you can auto-approve the easy cases and escalate the uncertain ones.
You describe the state and the questions. Jev evaluates them all in a single round trip and returns typed values with probabilities.
Pick one of up to 255 labelled options. Returns the winning key, per-option probabilities and a confidence.
Place the input on a 2–10 level ordered spectrum. Returns a fractional score plus the full distribution.
A calibrated yes/no as a probability from 0 to 1 — perfect for gates, filters and guardrails.
Paste your own state and questions into the playground — it runs against the real API, free.
