AI USE CASES

How to send quick questions to a cheap model and hard tasks to a strong one with magpie

Use intent routing so a small model reads each turn and picks the model that fits it.

Evidence: X, Oct 2026

Similar to what people reported. The steps and prompt below are AI written, not copied from those posts.

Who it is forDeveloper whose big model gets burned on simple questions like "what does this do?"

The problemEvery turn goes to the same expensive model, even trivial ones, which wastes quota.

The outcomeSimple questions go to a fast model while test-writing and heavier work go to the strong model.

What you need first

  • macOS, Windows, Linux, Docker or Termux
  • At least one coding agent already installed (for example Claude Code, Codex or Gemini CLI)
  • At least one provider: an API key, a local model server, or a signed-in subscription such as Claude, ChatGPT, Copilot, Gemini or Grok
  • Bun is downloaded automatically the first time a plugin needs it

Steps

  1. Create a routing group containing a fast model and a strong model
  2. Turn on intent routing for the group using the setup in the intent docs at usemagpie.ai/docs/intent
  3. Point your agent at the group and ask one quick question, then one bigger task
  4. Open the Routing view to see which model handled each turn

Prompt for your agent

Set up yetone/magpie intent routing so <FAST_MODEL> handles simple questions and <STRONG_MODEL> handles test writing. Confirm in the Routing view that two different turns went to different models.

Caveat. Intent routing needs a small model of your choice to classify each turn, which adds a call per turn. Exact setup steps are in the linked docs, not the truncated README.
