Show full answer Show less ## New Features * **Yokohama:** Introduced the ability to create custom AI agents and skills in AI Agent Studio to assist application users, enhancing workflow automation and AI integration within custom applications. * **Zurich:** Added a custom app record summarization skill for Now Assist, enabling automatic generation of summaries for records in specified tables. This feature supports in-product summarization via a button on records or through chat interaction, improving user productivity. * **Zurich:** Expanded third-party AI model provider options for Now Assist, including Google Gemini 2.0 Flash, Google Gemini 2.5 Pro, and AWS Claude 3.7 Sonnet, alongside existing providers such as Now LLM Service and Azure OpenAI GPT-4.1 variants. ## Changes * **Now Assist Usage Measurement:** Both Yokohama (starting Patch 5) and Zurich releases transitioned usage tracking from a 365-day look-back model to a 365-day burn-down model resetting on the contract anniversary date. This affects how AI usage is monitored and reported. * **Default Skill Activation:** In Yokohama Patch 11, certain Now Assist skills are now enabled by default for new installs and previously unconfigured skills during upgrades, simplifying initial setup. * **Access Control Enhancements:** Introduced configuration of ACLs for AI agents and agentic workflows in AI Agent Studio, allowing admins to control discovery, triggering, and user impersonation behavior (dynamic user vs. AI user), as well as access scope (authenticated users vs. public). ## Removed and Deprecated Features No features or functionalities were removed or deprecated between Yokohama and Zurich releases. ## Activation and Installation ServiceNow Otto for App Engine must be requested and installed via the ServiceNow Store. Customers are advised to review the activation information provided in the release notes for both Yokohama and Zurich to ensure proper installation and access. ## Additional Requirements and Compatibility * **Yokohama:** Customers should verify their entitlements to confirm access to the ServiceNow Otto for App Engine application. * **Zurich:** No changes to additional requirements, browser compatibility, accessibility, or localization were noted. ## Highlights for Customers * Ability to build and deploy custom AI agents and skills tailored to application-specific workflows, accelerating digital transformation. * Enhanced Now Assist functionality with record summarization and expanded AI model provider options for improved AI capabilities. * Improved usage measurement model providing clearer insight into AI consumption tied to contract periods. * More granular security and access controls for AI agents and workflows to meet enterprise governance needs.
