Multi-AI agent router: compare OpenAI, Anthropic & Groq responses

Started by another system calling it. It calls services over plain HTTP rather than through connectors. It hands the judgement calls to Claude, Groq and one other. 16 steps, 1 branch: a working afternoon to understand properly.

Questions

What does it need to run?

An n8n account, and a key for Claude and Groq. You connect your own accounts after importing it; none are included.

What starts it?

It starts on another system calling it.

Does it use AI?

Yes. It calls Claude, Groq and OpenAI. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Plan an afternoon. 16 steps is enough that you should read each one before running it.

How do I import it?

Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts.

Before you run it

Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 16 steps before you point it at anything that matters.
