# Overview

> Deploy trained Luna metrics from the Luna Studio SDK to Galileo.

Once you are satisfied with your trained Luna metric's performance and compliance checks, you can deploy it to Galileo and use it across evaluation, observability, and guardrails.

## Registering a metric in Galileo

The SDK provides `register_metric_to_galileo(...)` for the final deployment step. After your model weights are available, registration creates or updates the scorer version in Galileo.
