Free setup · Jev · the model that decides instead of writing
A model that answers yes or no.
Here is the setup.
Jev does not write text. You hand it a situation and the answers it is allowed to give, and it hands back one answer and a confidence number. TypeSafe's own access is early access with a waitlist. There is a route that is open today. This is the exact model id, the first request, 5 things a business can do with it, the guardrails, and 2 open alternatives that need no key at all.

What's in the setup
What Jev is
A decision model, not a text model. The 3 question types, and why most agent steps are decisions.
Get it today
The exact OpenRouter model id, the pricing fields, and the list it does not appear in.
Your first request
A copy-paste curl and a Python file that return a decision, a confidence number and the cost.
5 business uses
Lead triage, buying signals, an approval gate, no-code routing, bookkeeping. One line each.
Guardrails
Log every decision, keep a human on money, set the confidence line, measure on your own data.
Open alternatives
SemIf runs in the browser with no key. NanoJev needs CUDA. Both MIT, both independent.
Do it with Claude Code
A copy-paste prompt that sets it up, runs one request, and never spends without asking.
Optional, not required for any of the above
I build one of these every week.
Inside AI Operators I break down the skills, prompts, and agent systems behind everything I ship, with weekly calls where I help you set them up.
