# Step 4 — Config and launch

> Review the run summary and launch training.

The final step is a summary view. Everything you've configured shows up as a card; you can jump back to any step with a **Change** link.

## Run summary

The page is titled **Run summary** with one card per artifact:

| Card         | What it shows                                                                                                                  |
| ------------ | ------------------------------------------------------------------------------------------------------------------------------ |
| Metric       | Selected metric template or custom prompt with a sparkles icon.                                                                |
| Test set     | Selected test set with validation status and (if available) F1 score pill.                                                     |
| Training set | Selected training set with validation status. For uploads with a label column, the line reads "Dataset validated and labeled". |
| Base model   | Pre-selected base model based on the approved Luna model for your organization.                                                |

Each card has a **Change** link in the top right that jumps you back to that step.

## Confirm and launch

When you click the **Confirm and launch** button, the run is submitted to Luna Studio and the following happens:

1. Saves the run with status **Queued**.
2. Allocates training resources for the picked base model.
3. Begins fine-tuning on the training set.
4. Evaluates the resulting metric against the test set.
5. Transitions the run to **Fine-tuned** (or **Failed**).
