# Using ServiceNow Otto for Enterprise Architecture \(EA\)

With the ServiceNow Otto for Enterprise Architecture \(EA\) application, you can use generative AI skills to summarize and refine content, generate and compare diagrams, and gather insights into business applications. You can also query your enterprise architecture portfolio using natural language in the Enterprise Architecture Workspace.

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 to define which options are available, then set the skill-level preferences in the [AI Admin Hub console](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/manage-large-language-models.md). For more information, see [Large language models on the ServiceNow AI Platform](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/exploring-large-language-models.md).

**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.

**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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/intelligent-experiences/ai-native-sku-overview.md).
