Open-source auto-router prices cache-aware model routing for Claude Code and Cursor

airesearch12 · x · 2026-09-21

A developer ships an update to the Jev auto-router: local open-source model support and reuse of your own Claude Code / Codex subscription. Each request is classified in 0.5s, every candidate model is priced for that exact request including redo risk, and the cheapest expected total wins; cheap answers get checked before you see them. Key insight: warm input cache bills the next turn at roughly a tenth of the price, so the real question per turn isn't 'which model is best' but whether a better model is worth losing the cache. MIT-licensed, sits in front of Claude Code, Codex, opencode or Cursor, reserving your plan's limits for hard work.
