modelmux

Use when someone has just cloned modelmux and wants to plug in OpenRouter and see heterogeneous routing working. Walks clone → install → key → run → verify, checking each step.

Use when someone wants to understand how modelmux works — why a proxy is needed, what signals it routes on, and how the cascade keeps the orchestrator on Claude while diverting chosen subagents.

Use when someone wants to change which OpenRouter (or Claude) models the proxy routes to — swapping a model behind an alias, retargeting an agent, overriding at runtime, or checking that slugs are still live.
