Let AI decide. Let code control the action.
Understand TypeSafe AI's Jev, compare open reimplementations, and put Choice, Score and Noul decisions into real software workflows. This is an independent, source-led research site.

Support ticket: a customer was charged twice. Which team owns it?
Start with the question.
Understand the model, choose an API or open alternative, then copy a working pattern.
What is Jev?
System One, typed decisions, probabilities and confidence.
Read the overview →APIHow do I call Jev?
From state and questions to a first request.
Open the quickstart →Open sourceAre there reimplementations?
Separate trained models, local engines and API compatibility layers.
Browse the directory →Put one decision into software.
The useful boundary is state → typed questions → probabilities → a deterministic code gate.
Three useful starting points.
Search-friendly pages that lead to practical implementation.
Jev vs JSON Mode
Format constraints and typed decisions solve different problems.
Read the comparison →WorkflowSupport ticket routing
Route, score urgency and escalate uncertain cases.
See the workflow →UpdatesJev and open-source news
Track versions, projects, evaluations and original sources.
Read the updates →Have a decision to wire into a product?
Try a Direct API access pattern first, then compare hosted Jev, open models and hybrid designs.
