## What it does

Routes an application's image, video or audio generation through a saved Runway Model Router configuration, and inspects or manages routers on request. It resolves the live config and current router docs, and explains why a routed request landed on a given model.

## Use when

- Swapping models without code changes
- Inspecting or editing a Model Router

## Not for

- A fixed, direct model endpoint (use Runway Dev Models)

## Install

- Claude Code: `claude plugin marketplace add runwayml/skills && claude plugin install runway-api@runway-dev`
- Codex: `npx skills add runwayml/skills --skill runway-dev-model-routers -a codex`
- Cursor: `npx skills add runwayml/skills --skill runway-dev-model-routers -a cursor`
- Gemini CLI: `npx skills add runwayml/skills --skill runway-dev-model-routers -a gemini-cli`
