## Key Features

* **Custom Resource Path for BYOK Models:** Configure a custom resource path for Azure OpenAI deployments to support endpoints with additional path segments, enhancing integration flexibility.
* **Administrator Access to Gen AI Logs:** Access the `sysgenerativeailog` table for debugging, with HR-related records restricted to HR administrators for data privacy.
* **Enhanced AI Asset Inventory:** Track AI asset status and lifecycle details (e.g., retirement dates) via new metadata fields in the Model and Prompt tables, improving asset visibility.
* **Long-Term Stable (LTS) Model:** Promote regulatory alignment and predictable AI behavior by using an LTS model designed for stability and confidence in integration.
* **AI Model Version Mappings:** Review mappings of AI model versions and providers in the Gen AI Model Version Mapping table, helping customers manage model relationships and metadata.
* **LLM Information Identification:** Identify third-party large language model (LLM) details such as model version and requested language via the Gen AI Log Metadata table.
* **Domain-Based LLM Usage Restrictions:** Enable or disable Now Assist per domain to control AI usage and comply with data processing policies.
* **Global Model Selection for Conversational Skills:** Now Assist admins can select between GPT-4.0 and Now Assist LLM models globally, supporting regional compliance and user needs.
* **Extended Log Retention:** Generative AI logs are retained for 180 days (up from 30) to meet extended compliance and auditing requirements.
* **Localization Support:** Dynamic translation for Now Assist is supported via Microsoft Azure OEM, configurable through the AI Admin Hub console for multilingual environments.

## Key Changes

* **Now Assist Usage Measurement:** Transition from a 365-day look-back model to a 365-day burn-down model with annual reset on the contract anniversary date, improving usage tracking accuracy.
* **Default Now Assist Skill Activation:** For new customers, designated Now Assist skills activate automatically upon installation. Existing customers upgrading from Yokohama Patch 11 will have unconfigured skills turned on by default, while previously deactivated skills remain off.
* **Access Control Enhancements:** ACLs are required for all AI capabilities to enhance security. Direct action calls in the Generative AI Controller were removed starting Zurich Patch 5. Custom AI functionality should now use the AI Skill Kit.
* **Data Privacy Application Usage:** Sensitive Data Handler dependency removed; data anonymization and privacy controls are now managed via the Data Privacy application for better PII protection.

## Activation and Upgrade Guidance

The Generative AI Controller is activated automatically with the installation or update of a Now Assist application. Customers should review pre- and post-upgrade tasks and consult knowledge articles or open support cases if installation or update issues occur. The feature is available through the ServiceNow Store.

## Additional Information

* **Security Compliance:** HR-related logs remain restricted to HR administrators, ensuring compliance with sensitive data policies.
* **AI Agent and Agentic Workflow ACL Configuration:** Administrators can control discovery and triggering permissions for AI agents and workflows, defining visibility and user roles.
* **Browser and Accessibility:** No new browser requirements or accessibility updates were noted between Yokohama and Zurich releases.
* **No Removals or New Deprecations:** No features were removed or deprecated in the Zurich release following Yokohama.

## What to Expect After Upgrading

* Improved AI asset management and lifecycle tracking through enhanced metadata fields.
* Greater control over AI model selection and domain-specific AI usage restrictions.
* Enhanced security with ACL enforcement for AI capabilities and removal of unsupported direct action calls.
* Extended log retention for compliance and better debugging capabilities.
* The ability to connect custom Azure OpenAI endpoints via configurable resource paths.
* Streamlined usage measurement aligned with contract terms for accurate billing and monitoring.

For more information, refer to [KB KB2704710: Now Assist Usage - Overview \& New Measurement Logic](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2704710). [Some Now Assist skills are turned on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&family=yokohama&ft:locale=en-US) :   The new default behavior works as follows: * New customers: When you install a Now Assist product, designated skills are turned on automatically. * Existing customers who are upgrading (starting with Yokohama Patch 11): Any previously unconfigured skill is turned on automatically (the skill was never configured and turned on, then turned off again). Previously configured skills that were turned on, then off, remain inactive. [Configure ACLs for AI agents and agentic workflows](https://www.servicenow.com/docs/access?context=aia-security-implementation&family=yokohama&ft:locale=en-US) :   Configure the access control lists for who can discover and trigger AI agents and agentic workflows in their guided setups in AI Agent Studio.
