+## Choosing the right path
+
+- Use the shared provider-backed path when you want model selection, provider failover, and the built-in async task/status flow.
+- Use a plugin path such as ComfyUI when you need a custom workflow graph or a provider that is not part of the shared bundled music capability.
+- If you are debugging ComfyUI-specific behavior, see [ComfyUI](/providers/comfy). If you are debugging shared provider behavior, start with [Google (Gemini)](/providers/google) or [MiniMax](/providers/minimax).
