# Define and preview model run

> Once you've selected the data and the model, the next step in your Foundry process is to define your model run parameters and (optionally) verify results.

Specific settings vary according to the selected model and what you're attempting to do. For example, some models require ontologies while others provide advanced settings to refine results.

Here, you:

* Define **model run settings**
* **Generate previews** to verify your model run settings
* Name and **submit** your model run.

The following sections discuss typical settings that do not necessarily apply to all situations.

## Model settings

The Model panel displays the name of the selected model and lets you use settings from other model runs using the same model.

Use **Load model run config** to use settings from earlier model runs. When you do so, a menu displays model runs based on the same model. You can search for specific model runs (case-insensitive).

Some models display a **Save as App** button, which lets you save the current model run as a [Foundry app](/horizon/guides/foundry-apps).

## Ontology settings

The **Ontology** panel previews the current ontology and its features.

When **Select an ontology** is displayed, you need to choose the ontology for the model run. Use **Select an ontology** to do so.

When you choose this option, the **Select ontology** view lists available ontologies.

You can only select ontologies compatible with your data and your model.

You can filter the ontology list. Use:

* **All** to display all available ontologies.
* **Previously with this model** to display ontologies used in earlier model runs. (This list may be empty).
* **Search** to locate specific ontologies by name (case-insensitive) filter.

To choose an ontology, select it.

Once you've selected an ontology, you can use:

* **Edit** to manage ontology features for your model run.
* **Disconnect** to change the selected ontology.

When displayed, the **Prompt** and **Examples** options lets you refine how the model interacts with the data. Syntax and options vary according to the model.

Use displayed, you can use **Generate example** to see a simple example for your model.

To learn more about valid prompts and example syntax, consult the appropriate docs for your model.

## Additional settings

Depending on the model, the task, and your data, additional settings may appear. For example, **Confidence threshold** appears for models that support that option.

Additional settings may also be displayed.

**Advanced model settings** show additional configuration options supported by your model. These often include hints that describe purpose and acceptable value ranges.

## Generate previews

Optionally, you can use **Generate preview** to verify the results of your current model run settings. This processes your model run against a limited number of data rows (up to five).

Depending on capacity, this can take several minutes to complete, as it involves setting up and running an instance of your selected model.

Select **Stop** to cancel preview generation.

## Submit model run

The **Submit** button appears only when your settings are valid for the selected model, ontology, and underlying data types. For example, you cannot submit a model run for models that require an ontology until you select an ontology.

When satisfied with the settings and generated previews, name and submit your model run.

## Next Steps

At this point, you need to wait until you model run completes. You can track progress or do other things.
