Classifier & router playground
Paste any prompt. See what task category the classifier assigns, which model model="auto" would route it to, and what that costs vs. sending every request to the frontier.
Don't want to think of one? Pull a random prompt — then edit it however you like.

The classifier and router will run client-side. No API calls; no signup.
