Jev is a System One model: it doesn't write prose, it returns typed decisions with calibrated probabilities. Paste any text below and watch nine of them come back in a single request — charted, shareable, and impossible to parse wrong.
Message X-ray
What is this message actually asking of you?
state Jev reads. 0 / 12,000Appears in Explore and in search results.
Three question types
Everything Jev can answer is one of three shapes. Below, all three are answered against the same eleven-word state — the example straight out of the TypeSafe docs.
"Help! My payouts have been failing for 3 days."
Noul
Does this convey urgency?
A yes/no question comes back as a probability, not a word. 0.96 and 0.51 are different answers, and your code can tell them apart.
How a Noul worksChoice
Which team should handle this?
One option out of a set you define, with the full distribution behind it — so you can see the runner-up and how close it was.
How a Choice worksScore
How frustrated is the customer?
- 0 Calm 0%
- 1 Frustrated 76%
- 2 Very angry 24%
A rating against ordered levels you write. The answer is probability-weighted, so it lands between levels when the text does.
How a Score worksNine questions, one call. Jev reads the state once and answers every question against it in parallel.
Answers arrive typed. No JSON mode, no retries on malformed output, no regex over prose.
Noul, Choice, Score. Every decision your software needs is one of these three shapes.
Choice and Score carry a confidence value, so "I am not sure" is a branch your code can take.
Coming from an LLM?
The same routing decision written both ways — and where the retry loop goes.

Typed decisions, all the way down
