# Fine-Tune, Test, and Optimize an Ensemble Retriever

Customize, test, and validate ensemble retriever responses in the Data 360 Retriever Playground. Avoid irrelevant output, eroded user trust, and increased costs by verifying response accuracy directly in the playground without calling an LLM or manually testing in local environments.

**Where:** This change applies to Data 360 in Enterprise, Performance, Unlimited, and Developer editions.

**When:** This feature is available starting August 2026.

**How:** From the **AI Models** tab, select **Test Retriever**. Or, test an ensemble retriever from the retriever's action menu.
