Jev: Typed Decisions for Bounded Answer Spaces
Carpe Diem@Ask_CarpeDiem
Jev is a system that takes unstructured input and outputs typed decisions with probabilities, designed for narrow, bounded decision-making tasks rather than generative language.
TakeThat’s the whole language: → Choice: one option from the list you declare (up to 255) → Score: a rating on the scale you define → Noul: yes/no as a probability You keep the thresholds.
Pattern↑ State to typed decisions for software
We’ve been sending Ferraris to the grocery store for two years.
Every micro-decision an agent makes — is this ticket urgent, billing or engineering, is that shell command dangerous, does this retrieved passage actually answer the question — got shipped to a general-purpose LLM. The model wrote. The app parsed. You retried when the JSON was wrong. Slow. Expensive. Absurd for a decision with five possible answers.
On September 15, TypeSafe shipped Jev.
It is not a chatbot. It writes nothing. No paragraph, no code, no apology. Unstructured state in. Typed decision plus probabilities out. 70 to 500 ms. Output is free.
Three primitives. That’s the whole language:
→ Choice: one option from the list you declare (up to 255)
→ Score: a rating on the scale you define
→ Noul: yes/no as a probability
You keep the thresholds. Your code decides whether 91% routes automatically and whether 52/48 gets escalated. Jev judges meaning. You own the consequences.
The marketing says “zero hallucinations.” True in a narrow sense: it cannot leave the schema. It can still pick the wrong option among the allowed ones. Type safety is not infallibility.
Where it actually changes the economics: the thousands of narrow judgments software makes all day. Triage. Agent guardrails. Model routing. RAG checks. Moderation. Not for writing. Not for multi-step dependent reasoning. For evaluating known paths, in parallel, at a cost an invoice barely notices.
LLMs generate language when the answer space is open.
Jev evaluates known paths when the answer space is bounded.
Jev is on Carpe Diem — still cheaper than anywhere else. And still anonymous.
