Analyzes each question and sends it to the AI model best suited to answer it, saving cost and improving accuracy.

How the work actually flows

It branches. Exactly one path is taken.

The problem it solves

Running every question through your most expensive AI model burns through your budget fast, but using only cheap models gives weak answers for harder questions. Picking the right tool for each question by hand isn't realistic at any real volume.

Who it fits

Businesses running AI-powered chat tools or assistants who want quality answers without overspending on every query.

How it works

  1. A user sends a question into the chat
  2. AI reviews the question and decides which model is best suited to answer it
  3. The question is routed to the selected model, whether it's built for coding, reasoning, or search
  4. The response comes back through the same chat
What you get

Each question landing with the right model

Every question your users ask gets automatically paired with the AI model best equipped to answer it well.

What you get

An AI-generated answer produced by whichever model best fits the question, without you managing that choice.

What you need

An OpenRouter account and API access to the underlying AI models.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
