Once a run reaches Fine-tuned, you can register the resulting metric. Registration publishes the metric to the Galileo metrics store, where it becomes available across the Galileo platform — for evaluation in experiments, Log streams, and runtime guardrails using Protect / Agent Control.

​
Prerequisites

​
Where you can register from

The Register metric action appears in three places:
  • Run details page — primary footer button on Fine-tuned runs.
  • Training runs table — an action link on each Fine-tuned row. See Training runs home.
  • Metrics page — an action link on each Fine-tuned metric. See Metrics overview.
All three open the same Register metric flow.

​
Steps

1

Click Register metric

From the run details footer, the runs table row, or the metrics page row.
2

Enter a metric name

Use a name that’s clear in the Galileo metrics store, where it’ll sit alongside built-in metrics. Examples: support-tone-strict, pii-detector-en.
3

Click Register

The modal closes. The run’s status flips to Registered and the Register metric affordance disappears for that run.

​
Naming guidance

  • Use lowercase with hyphens: customer-tone-classifier, not Customer Tone Classifier.
  • Include the language or domain if relevant: pii-detector-en, legal-toxicity.
  • Add version suffixes (-v1, -v2) if you are registering multiple variants.
Metric names should be unique within your Galileo workspace. If a metric with the same name already exists, registration fails with a duplicate-name error. Pick a different name and try again.
