Live demo
Write a customer ticket or pick an example. Jev answers two sets of typed questions. Then plain code decides: which agent, which model, how much reasoning. Everything happens in front of you, with the real requests on the right.
Jev call 1: department, urgency, frustration.
department
In your code: the department picks the agent. Urgency and frustration can escalate to a human.
Jev call 2, with the chosen agent in the state: complexity and stakes.
complexity
In your code: model tier and reasoning depth.
Calls go through an open-source relay that stores and logs nothing. It only accepts this demo’s questions, 1,000 characters at most, and 20 calls a minute. Do not enter personal data: Jev is hosted in the United States. The model names fast-8b, balanced-70b and frontier-1200 are illustrative: the demo does not call them. Source code: jev-router.
