## Important Upgrade Information

* Generative AI Controller updates are tied to installing or updating any Now Assist application.
* For installation or update issues, customers should consult the relevant knowledge articles or open a Support case.
* Pre- and post-upgrade tasks should be reviewed and completed to ensure proper functioning post-upgrade.

## Key Features Introduced Between Xanadu and Zurich

* **Metadata Logging:** Introduction of a metadata log table capturing request details, feedback, and error codes for improved monitoring.
* **Multilingual Support:** Enhanced translation capabilities including dynamic translation powered by Microsoft Azure OEM, configurable via the AI Admin Hub console.
* **Global Model Selection:** Admins can globally choose between GPT-4.0 and Now Assist LLM models to comply with regional data policies and improve performance for users in regions like APAC.
* **BYOK Custom Resource Path:** Support for configuring custom resource paths for Azure OpenAI deployments with bring your own key (BYOK) models, enabling better integration with Azure endpoints.
* **Enhanced Logging and Inventory:** Extended retention of generative AI event logs from 30 to 180 days for compliance, plus improved AI asset tracking and lifecycle management through new metadata fields in AI Control Tower.
* **Long-Term Stable (LTS) Model:** Introduction of an LTS model providing regulatory alignment and predictable behavior for enterprise-grade stability.
* **LLM Usage Control:** Ability to restrict or enable Now Assist AI capabilities by domain to control AI data processing and ensure compliance.
* **Access to Debugging Logs:** Enhanced administrator access to Gen AI log tables with HR-related records restricted to HR admins for security.
* **AI Model and Version Mapping:** Tables showing mappings between AI models, providers, versions, and associated metadata to support transparency and management.

## Notable Changes

* Updated prompts and filtering methods for generative AI capabilities to improve latency and processing efficiency.
* Transition from a 365-day look-back to a 365-day burn-down model for Now Assist AI usage measurement, resetting at contract anniversary.
* Default activation of certain Now Assist skills for new customers and unconfigured skills for upgrading customers to simplify onboarding.
* Access control configuration enhancements for AI agents and agentic workflows, enabling fine-grained permissions and data privacy compliance using the Data Privacy application instead of Sensitive Data Handler.
* Removal of direct action calls in Zurich Patch 5 to enforce security via ACLs; custom AI functionality should now be created using AI Skill Kit.

## Deprecations and Removals

* No features or functionality were removed in these releases.
* The dependency on the Sensitive Data Handler was removed and replaced by the Data Privacy application for PII anonymization starting in Yokohama.

## Activation and Access

* Generative AI Controller is available as part of the ServiceNow AI Platform with activation of any Now Assist application.
* It is available through the ServiceNow Store and requires installation of Now Assist plugins.

## Localization and Accessibility

* Supports multi-language dynamic translation via Microsoft Azure OEM.
* No new accessibility or browser-specific requirements were introduced.

## Practical Implications for ServiceNow Customers

* Upgrading to Zurich enables extended logging and compliance with longer data retention policies.
* Admins gain enhanced control over AI model selection, usage restrictions by domain, and access to detailed logs for debugging.
* Integration with Azure OpenAI BYOK deployments is more flexible with custom resource path configuration.
* Security improvements through ACL enforcement require adoption of the AI Skill Kit for custom generative AI workflows.
* Data privacy management is simplified through the Data Privacy application, supporting compliance with PII protection standards.

## Changes

Between your current release family and Zurich, some changes were made to existing Generative AI Controller features.  
{#dfrn3-generativeaicontroller-summary__entry__18}

| Release | Release notes |
|-|-|
| Xanadu | [Directions for generative AI updates for Generative AI Controller](https://www.servicenow.com/docs/access?context=reference-for-generative-ai-controller&family=xanadu&ft:locale=en-US) :   The prompts, which are the instructions to the large language model (LLM), for all four capabilities (Generic Prompt, Generate Content, Summarization, and Sentiment Analysis), semantic filtering, and recursive summarization have been updated. |
| Yokohama | [Changes to Now Assist usage measurement](https://www.servicenow.com/docs/access?context=monitoring-now-assist-usage&family=yokohama&ft:locale=en-US) :   Starting with Yokohama Patch 5, Now Assist usage measurement is transitioning from a 365-day look-back model to a 365-day burn-down model, with usage resetting at the contract anniversary date. 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. You can determine whether an AI agent or agentic workflow behaves as a dynamic user or as an AI user. You can also specify if an AI agent or agentic workflow can be available to all authenticated users or publicly available. [Configure Data Privacy and Data Discovery to protect the personally identifying information (PII) of your users.](https://www.servicenow.com/docs/access?context=configure-now-assist-data-privacy&family=yokohama&ft:locale=en-US) :   Generative AI Controller has changed to use the Data Privacy application instead of the Sensitive Data Handler to help anonymize PII.

For more information, refer to [KB KB2704710: AI Usage - Overview \& New Measurement Logic](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2704710). [Direct action calls removed from Generative AI Controller](https://www.servicenow.com/docs/access?context=now-assist-skill-kit-landing&family=zurich&ft:locale=en-US) :   Starting with Zurich Patch 5, the Generative AI Controller (GAIC) no longer supports direct action calls in order to support the security requirements that all AI capabilities be protected by Access Control Lists (ACLs). To create custom generative AI functionality, use AI Skill Kit instead. * Configure actions in the Generative AI Controller * Generate Content to create AI-generated text responses * QnA to answer user questions * Summarize to shorten long or complex text * Generic Prompt to generate ideas or content on any topic * Sentiment Analysis to identify the sentiment of user input For more information, refer to [KB KB2716977: Generative AI Controller actions are no longer avaliable for custom workflows](https://support.servicenow.com/kb?sys_kb_id=6460540047ee7a9048cb2920326d4302&id=kb_article_view). |
