Jevonian: an open-source local router that uses Jev to pick models for coding agents

Jevonian is an open-source local router that uses Jev to choose the model and thinking effort for each coding turn, showing what ran, why it was picked, and the estimated cost.

Jev doesn’t write code. I use it to decide which model should. I built Jevonian, an open-source local router for coding agents. Keep your agent. Jev picks the model and thinking effort for each turn. See what ran, why it was picked, and its estimated cost. Built with @typesafeai’s Jev. Early beta — looking for people to try it on real coding tasks. http://github.com/xinyao27/jevonian
