Jev playground: test your own decision rules.
A Jev API workspace for support, sales, and operations. Define your labels, test a real message, and route uncertain results to a person.
Your decision
Illustrative sample — not a live model response.
Run a decision or open the labeled sample to see the result here.
A high score is not a guarantee. Keep a person in control of consequential actions.
API docs →Questions before your first decision
Is this the official Jev website?
No. Jev API Pro is an independent workspace. Jev is a model from TypeSafe, accessed here through OpenRouter.
Can I try it without an account?
Yes, when live decisions are available: up to three attempts per source address per UTC day, subject to shared trial capacity. A labeled example is also available.
What happens when the model fails?
We show an explicit error. Failed account decisions are refunded, and we do not substitute a different model silently.
Do you store the messages I submit?
Decision history stores the result, request hash, and operational metadata, not the submitted message. Your text is sent to OpenRouter and its model provider for inference.
What does a credit buy?
One completed classification within the published input limits uses one credit. Signed-in accounts receive 20 signup credits and can claim two daily check-in credits.
Can I automate business actions?
Use the API to get decisions. Your own application checks permissions and performs actions. Low-confidence or missing-confidence results should go to review.
