# Evaluate models

> Compare vendor models side by side on the leaderboard.

Navigate to the Leaderboard section of your use case to compare submitted models, for example the [Breast Cancer Screening Use Case](https://ai.tracebloc.io/explore/ai-breast-cancer-screening-and-image-classification?tab=leaderboard).

## The Leaderboard

Vendors are ranked by the score of their best performing model. Scores are calculated using the evaluation metric you selected when [defining the use case](/create-use-case/define#supported-metrics-per-data-type-and-task) (e.g. Accuracy, F1, mAP).

### Leaderboard Columns

| Column             | Description                                                                       |
| ------------------ | --------------------------------------------------------------------------------- |
| Rank               | Position based on the best model score. Lower rank = better performance.          |
| Team / Vendor      | The participant or team that submitted the model.                                 |
| Score              | The model's evaluation result on your test data, using the metric you defined.    |
| Model Size         | Size of the submitted model in parameters or MB. Useful for comparing efficiency. |
| Energy Consumption | Compute resources consumed during training. Helps assess cost-efficiency.         |
| Submissions        | Total number of models submitted by the team.                                     |
| Remaining Budget   | How much of the allocated compute budget (in PFLOPs) the team has left.           |

### Actions You Can Take

From the use case view, you can:

* **Compare models** — Use the leaderboard to identify the best performing and most efficient models side by side.
* **Stop or adjust training** — Reduce or revoke a team's remaining compute budget to control costs or end a round of evaluation.
* **Contact participants** — Reach out to vendors or researchers directly to discuss results, request further iterations, or negotiate next steps.
* **Select a winner** — Once evaluation is complete, choose the best model based on score, model size, and resource efficiency.

## Supported Evaluation Metrics

Scores on the leaderboard are calculated using the metric you selected when defining the use case. See the full list of [supported metrics per data type and task](/create-use-case/define#supported-metrics-per-data-type-and-task).
