Show full answer Show less ## Key Features in Yokohama * **Knowledge Graph Schema Testing:** Users can enter queries and test Knowledge Graph schemas using various large language model (LLM) options, including adding previous conversations for context. * **Prebuilt Schemas:** A new natural language query (NLQ) graph schema is available alongside user profile schemas, simplifying schema management. * **Prebuilt Integrations with Virtual Agent:** Knowledge Graph integrates with Now Assist Virtual Agent to provide personalized, context-aware responses on people queries, supports slot filling, and enhances Virtual Agent topic execution using LLM-driven APIs. * **Knowledge Graph Designer:** Administrators can create, edit, duplicate, and delete Knowledge Graph schemas, including nodes, properties, and edges via an intuitive interface. * **Integration with AI Agents:** Knowledge Graph supports integration with Now Assist AI agents for personalized user context and can act as a tool to execute specific tasks assigned to AI agents. * **Expanded LLM Model Support:** Besides Now LLM Service and Azure OpenAI GPT models, Yokohama supports Google Gemini and Anthropic Claude AI models through ServiceNow's third-party model strategy. * **Data Fabric Integration:** Schema creation now supports Workflow Data Fabric tables enabling secure, efficient retrieval of data across systems without data movement. * **Enhanced Query Support:** Supports aggregate queries and CMDB queries within the Now Assist panel, improving data interaction capabilities. ## Important Upgrade and Activation Information * Knowledge Graph is activated by default for customers who have downloaded the Generative AI for Business Unit (BU) application. * Ensure your instance is upgraded to XP7 to meet Knowledge Graph requirements. * Post-upgrade, configure access control lists (ACLs) for AI agents and agentic workflows to define who can discover and trigger these AI capabilities within AI Agent Studio. * Changes to Now Assist usage measurement: Starting from Yokohama Patch 5, usage resets annually at the contract anniversary date following a burn-down model rather than a rolling 365-day look-back. * Some Now Assist skills and AI agents are enabled by default for new customers and certain existing customers after upgrading (starting with Patch 11), reducing initial configuration effort. ## Changes and Improvements * Default enablement of select Now Assist skills and AI agents to streamline setup for new and upgrading customers. * Improved accuracy of Now LLM Service for enhanced response quality. * Support for hierarchical nodes (parent and grandparent) in Knowledge Graph queries. * Enhanced personalization and contextual relevance through deeper integration with Now Assist across Virtual Agent, AI Agents, and AI Search. ## Removed and Deprecated Features No features were removed or deprecated between Xanadu and Yokohama releases for Knowledge Graph. ## Practical Impact for ServiceNow Customers By upgrading to Yokohama, customers can expect a richer, more integrated Knowledge Graph experience that enhances Virtual Agent and AI Agent capabilities through improved schema management, expanded LLM options, and streamlined AI skill enablement. The enhancements facilitate delivering personalized, context-driven interactions and efficient data retrieval without complex data migrations. Proper configuration of ACLs and awareness of usage measurement changes will help optimize AI resource management and compliance.
