Its README says it sends simple work to a fast tier and difficult work to a stronger tier, while launching the native CLI and preserving its tools, sessions, permissions, and authentication. Setup requires Node.js 20.12 or later, a supported CLI, and a Jev API key. The project uses a loopback proxy and offers controls to pause routing by selecting a concrete model. The repository describes the implementation and setup; the supplied evidence does not establish cost savings, routing accuracy, or comparative performance.
