Use it to: * Test how any prompt gets routed before it goes to production * See exactly which tier, model, and confidence score Routor assigns * Create **Routing Profiles**, saved configurations that give your app custom routing rules * Experiment with tier floors, ceilings, and capability caps without touching any code Playground - type a prompt, see the tier, model, confidence, and savings instantly *** ## What You Can Do ### Test a Prompt Type any prompt and hit **Route**. Routor shows you: * Which **tier** it classified as (NANO, SIMPLE, LIGHT, STANDARD, COMPLEX) * Which **model** it would pick * The **confidence score** for the classification * The full **fallback chain**, meaning which models it would try if the first fails * **Cost estimate** compared to the baseline cost > 📷 **\[Screenshot: Prompt "explain closures in JavaScript" showing LIGHT tier, Kimi K2.6 model, 0.82 confidence, and cost comparison]** *** ### Create a Routing Profile A **Routing Profile** is a named set of routing rules attached to an API key. Think of it as a config file for how Routor should behave for a specific app or use case. Each profile gets its own dedicated API key, so you can have different routing behavior per app, environment, or team without changing any code. What a profile can do: * Force all requests to use at least STANDARD tier for a production feature * Cap costs by setting LIGHT as the maximum tier for an internal tool * Enable tool-calling routing for an agent * Set a BFCL accuracy minimum for agents that need reliable function calling See [Creating a Routing Profile](create-profile.md) for the full walkthrough. *** ### Browse Routing Decisions The Playground shows a live feed of routing decisions as they happen. Click any request to see the full classification breakdown. > 📷 **\[Screenshot: Routing decisions list showing timestamps, prompts truncated, tier badges, model names, and savings percentages]** *** ## Profile Limit Every account includes **1 routing profile** with its own dedicated API key — enough to test and run a single configuration. Accounts are limited to 1 profile for now; there are no paid profile plans currently.
