FAQ
Common questions about Jev and JevKit.
The details that matter when trying the live playground or integrating the same decision pattern into software.
What is Jev?
Jev is TypeSafe AI's System One model for structured decisions. Its public API accepts state plus typed questions and returns structured answers with probability information.
Is JevKit official?
No. JevKit is an independent playground and guide. Live requests are sent to the official TypeSafe AI Jev API.
What question types can I try?
The JevKit V1 playground supports the public Jev choice, score, and noul question shapes.
How many free calls do I get?
An anonymous visitor can make one real API call. A signed-in user can make five successful free calls.
Do failed API requests consume a free call?
Server and upstream failures are recorded as failed attempts and do not consume the successful-call allowance.
Does JevKit store the state or question I submit?
The V1 usage log stores metadata needed for quotas and API cost control, not the submitted state or question text.
