# Compare Enterprise Modeling and Visualization diagrams

# Compare Enterprise Modeling and Visualization diagrams {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 3 minutes to read  
Compare different versions of Enterprise Modeling and Visualization diagrams and learn the details of the differences from the summary that is generated by ServiceNow Otto® in the Enterprise Architecture Workspace.

## Before you begin

Note:  
Depending on your license, you will have access to certain application features, generative AI skills, agentic workflows, and AI agents. For more information, see [ServiceNow product tiers](https://www.servicenow.com/docs/access?context=ai-native-sku-overview&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US).  
Important:  
This generative AI skill is turned on by default. The skill will be automatically available to appropriate role users for the application. For more information, see [AI agents, skills, and agentic workflows on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US).

You can use Now LLM Service, Azure OpenAI, Google Gemini or Anthropic Claude as the AI model provider for all generative AI skills and AI agents. Use the Configuration Controls in [AI Control Tower](https://www.servicenow.com/docs/access?context=ai-model-providers&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US) to define which options are available, then set the skill-level preferences in the [AI Admin Hub console](https://www.servicenow.com/docs/access?context=manage-large-language-models&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US). For more information, see [Large language models on the ServiceNow AI Platform®](https://www.servicenow.com/docs/access?context=exploring-large-language-models&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US).

The default AI model provider for this skill is Azure OpenAI.  
Note:  
Starting with the September 2026 release, Gemma 4 joins our growing portfolio of open-weight models available through Now LLM Service. The latest industry advancements are available alongside sovereignty-focused options. All models are hosted and governed by ServiceNow with the same infrastructure and data protections. Older models will remain available for existing published AI skills, agents, and agentic workflows, but will no longer be available for new development or configuration. For details, see the [KB3066214: ServiceNow Otto Model Upgrades](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3066214) article in the Now Support Knowledge Base.

## About this task


Enterprise Modeling and Visualization diagrams often have complex architecture layers like business capabilities, application hierarchy, and process flows. Manual comparison can be time-consuming or
error-prone. Using the diagram change analysis ServiceNow Otto skill, you can quickly generate a change summary.

You can compare any two diagram versions, not just adjacent versions. For example, you can compare version 3.0 with version 1.0, or version 4 with version 2.

The change summary generated by ServiceNow Otto® includes an executive summary of changes between the primary version and the comparison version. The summary also includes details of shapes or entities that have been added, modified,
or removed.  
When you compare two diagram versions, the comparison screen highlights the differences on the canvas:

* New shapes added in the primary version are highlighted in green.
* New relationship lines added in the primary version are highlighted in green.
* Modified shapes are highlighted in yellow.
* Modified relationship lines are highlighted in yellow.

## Procedure

1. Navigate to WorkspacesEnterprise Architecture Workspace.
2. Open the Modeling page by selecting the Enterprise Modeling and Visualization icon (![Enterprise Modeling and Visualization icon.]()).
3. Select the diagram that you want to compare versions for.
4. Select Compare versions.  
   The Compare versions button isn't available when you open a diagram that has only one version.

   The Compare versions pop-up window appears.

5. In the Compare versions pop-up window select the versions that you want to compare:  
   1. Select the primary version of the diagram from the Primary version drop-down list.
   2. Select another version of the diagram from the Version to compare drop-down list.

   {#compare-modeling-diagrams__ol_zkk_wwz_f3c}  
   Note:  
   You can compare any two versions, not just consecutive versions. For example, you can compare version 3.0 directly with version 1.0.
6. Select Compare.  
   The Compare versions tab appears and a change summary is generated in the ServiceNow Otto side panel. The ServiceNow Otto side panel displays the following sections:
   * Executive summary: A ServiceNow Otto generated summary of the key changes between the selected versions.
   * Diagram changes: Changes to shapes, entities, or relationships that have been added, modified, or deleted.

     Note:  
     * Select the edit icon (![Edit icon.]()) to change the existing diagram versions and generate a fresh diagram comparison summary.
     * Select the refresh icon (![Refresh icon.]()) if you have changed the primary version of the diagram and want to generate a fresh diagram comparison summary.
     * Select the helpful icon (![Helpful icon.]()) or not helpful icon (![Not helpful icon.]()) to provide feedback on the change summary generated by ServiceNow Otto. This feedback helps ServiceNow Otto to generate better change summaries.
     * Select the copy summary icon (![Copy summary icon.]()) to copy the diagram change summary created by ServiceNow Otto.
     * Select the ServiceNow Otto icon (![ServiceNow Otto icon.]()) to close the side panel.
