Once you are satisfied with your trained Luna evaluator's performance and compliance checks, you can deploy it to Splunk Agent Observability and use it across evaluation, observability, and guardrails. ## Registering an evaluator in Splunk Agent Observability 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 Splunk Agent Observability. ## Where to go next Follow the code-first deployment flow to publish a trained evaluator. See the equivalent registration step in the Luna Studio web app.
