# Evaluating prompt templates in projects #

You can evaluate prompt templates in projects to measure the performance of foundation model tasks and understand how your model generates responses\.

With watsonx\.governance, you can evaluate prompt templates in projects to measure how effectively your foundation models generate responses for the following task types:

<!-- <ul> -->

 *  [Classification](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-samples.html#classification)
 *  [Summarization](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-samples.html#summarization)
 *  [Generation](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-samples.html#generation)
 *  [Question answering](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-samples.html#qa)
 *  [Entity extraction](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-samples.html#extraction)

<!-- </ul> -->

## Before you begin ##

You must have access to a watsonx\.governance project to evaluate prompt templates\. For more information, see [Setting up Watson OpenScale](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/wos-setup-wos.html)\.

To run evaluations, you must log in and [switch](https://dataplatform.cloud.ibm.com/docs/content/wsj/admin/personal-settings.html#account) to a watsonx account that has watsonx\.governance and watsonx\.ai instances that are installed and open a project\. You must be assigned the **Admin** or **Editor** roles for the account to open projects\.

In your project, you must use the watsonx\.ai [Prompt Lab](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-lab.html) to create and save a prompt template\. You must specify variables when you create prompt templates to enable evaluations\. The **Try** section in the Prompt Lab must contain at least one variable\.

Watch this video to see how to evaluate a prompt template in a project\.

This video provides a visual method to learn the concepts and tasks in this documentation\.

The following sections describe how to evaluate prompt templates in projects and review your evaluation results\.

## Running evaluations ##

To run prompt template evaluations, you can click **Evaluate** when you open a saved prompt template on the **Assets** tab in watsonx\.governance to open the **Evaluate prompt template** wizard\. You can run evaluations only if you are assigned the **Admin** or **Editor** roles for your project\.

### Select dimensions ###

The **Evaluate prompt template** wizard displays the dimensions that are available to evaluate for the task type that is associated with your prompt\. You can expand the dimensions to view the list of metrics that are used to evaluate the dimensions that you select\.

![Select dimensions to evaluate](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/images/wos-select-dimension-preprod-spaces.png)

watsonx\.governance automatically configures evaluations for each dimension with default settings\. To [configure evaluations](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/wos-monitors-overview.html) with different settings, you can select **Advanced settings** to set minimum sample sizes and threshold values for each metric as shown in the following example:

![Configure evaluations](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/images/wos-config-eval-settings.png)

### Select test data ###

You must upload a CSV file that contains test data with reference columns and columns for each prompt variable\. When the upload completes, you must also map [prompt variables](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/fm-prompt-variables.html#creating-prompt-variables) to the associated columns from your test data\.

![Select test data to upload](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/images/wos-select-test-data.png)

### Review and evaluate ###

Before you run your prompt template evaluation, you can review the selections for the prompt task type, the uploaded test data, and the type of evaluation that runs\.

## Reviewing evaluation results ##

When your evaluation completes, you can review a summary of your evaluation results on the **Evaluate** tab in watsonx\.governance to gain insights about your model performance\. The summary provides an overview of metric scores and violations of default score thresholds for your prompt template evaluations\.

If you are assigned the **Viewer** role for your project, you can select **Evaluate** from the asset list on the **Assets** tab to view evaluation results\.

![Run prompt template evaluation from asset list](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/images/wos-run-eval-asset.png)

To analyze results, you can click the arrow ![navigation arrow](https://dataplatform.cloud.ibm.com/docs/content/wsj/model/images/wos-nav-arrow.png) next to your prompt template evaluation to view data visualizations of your results over time\. You can also analyze results from the model health evaluation that is run by default during prompt template evaluations to understand how efficiently your model processes your data\.

The **Actions** menu also provides the following options to help you analyze your results:

<!-- <ul> -->

 *  **Evaluate now**: Run evaluation with a different test data set
 *  **All evaluations**: Display a history of your evaluations to understand how your results change over time\.
 *  **Configure monitors**: Configure evaluation thresholds and sample sizes\.
 *  **View model information**: View details about your model to understand how your deployment environment is set up\.

<!-- </ul> -->

If you [track prompt templates](https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/xgov-track-prompt-temp.html), you can review evaluation results to gain insights about your model performance throughout the AI lifecycle\.
