Release	Release notes
Xanadu	Xanadu Patch 3 Metadata log table for generative AI requests Use the new metadata log table that includes information about the requesting conversation, the capability definition, provided feedback (if any), and error codes. Translation for Now Assist Support users who speak different languages with new language information in LLM request metadata, better controls for Dynamic Translation, and translated text logging. Xanadu Patch 7 Global Model selection for conversational skills Enable Now Assist Admins to choose between GPT4.o and Now Assist LLM model for data routing at a global level. This ensures compliance with any regional restrictions and helpful for APAC users who may face limitations with US-based models, such as GPT-4.0.
Yokohama	Yokohama Patch 10 Administrator access to Gen AI log Access the Gen AI log [sys_generative_ai_log] table to gain insights for debugging purposes. HR-related records remain restricted to HR admins. Enhanced AI asset inventory Track the enhanced AI asset inventory through AI Control Tower using new metadata fields in the Model [sys_generative_ai_model_config] and Prompt [sys_generative_ai_config] tables. Gain better visibility into AI asset status and life-cycle details, such as retirement dates. Yokohama Patch 8 AI Model Version Mappings Review the mappings between AI model versions, their providers in the Gen AI Model Version Mapping [sys_gen_ai_model_version_mapping] table. It shows mapping between source and target models, along with associated metadata, such as skill type, model type, resource associations, and provider information. Yokohama Patch 6 Identify third-party LLM information Access the Gen AI Log Metadata [sys_gen_ai_log_metadata] table to identify which LLM model, version, and requested language was used to generate the AI content. Restrict LLM usage based on the domain Enable or disable Now Assist for each domain so that you can restrict the use of LLMs and avoid using AI for data processing, if needed. Yokohama Patch 1 Global Model selection for conversational skills Enable Now Assist Admins to choose between GPT4.o and Now Assist LLM model for data routing at a global level. This ensures compliance with any regional restrictions and helpful for APAC users who may face limitations with US-based models, such as GPT-4.0.
Zurich	Zurich Patch 4 Administrator access to Gen AI log Access the Gen AI log [sys_generative_ai_log] table to gain insights for debugging purposes. HR-related records remain restricted to HR admins. Enhanced AI asset inventory Track the enhanced AI asset inventory through AI Control Tower using new metadata fields in the Model [sys_generative_ai_model_config] and Prompt [sys_generative_ai_config] tables. Gain better visibility into AI asset status and life-cycle details, such as retirement dates. Long-Term Stable model for generative AI Promote stability and adoption for entitled users with a Long-Term Stable (LTS) model. The LTS model provides regulatory alignment, predictable behavior, and life cycle stability to integrate GenAI with confidence. Zurich Patch 2 AI Model Version Mappings Review the mappings between AI model versions and their providers in the Gen AI Model Version Mapping [sys_gen_ai_model_version_mapping] table.

Changes

Between your current release family and Zurich, some changes were made to existing Generative AI Controller features.


Release	Release notes
Xanadu	Directions for generative AI updates for Generative AI Controller 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	Yokohama Patch 11 Changes to Now Assist usage measurement 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. Some Now Assist skills are turned on by default 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. Yokohama Patch 1 Configure Data Privacy and Data Discovery to protect the personally identifying information (PII) of your users. Generative AI Controller has changed to use the Data Privacy application instead of the Sensitive Data Handler to help anonymize PII. The process for choosing what gets anonymized and how has shifted to different tables and forms that your administrator must configure for your organization.
Zurich	Zurich Patch 5 Changes to Now Assist usage measurement Starting with Zurich 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. Direct action calls removed from Generative AI Controller 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 Now Assist 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.
