## All three at once

Many teams use all three surfaces. A typical first day looks like:

1. **Public** — research the catalog, shortlist candidate models.
2. **Premium** — sign up, run a private evaluation against your data on the shortlist.
3. **SDK** — wire the winning evaluation into your code or CI gate.

You can switch between Public and Premium with the **Switch toggle** in the Premium top bar.

## Common pitfalls

* **Skipping the Public catalog and going straight to Premium.** You'll waste ECU running candidates that public scores would have ruled out.
* **Building a judge before you have a labeled set.** Judges only work as well as the labels you tune them against. Even 30 labels makes a meaningful difference.
* **Wiring CI gates before you've run the eval interactively.** Start in the Premium UI; promote to CI once you trust the result.
