Choose the large language model (LLM) service provider for Now Assist AI agents in AI Agent Studio.

## Before you begin

Role required: sn_aia.admin

## About this task

LLMs are part of the foundation of agentic AI. Different LLMs can provide slightly different performance and responses. You can select which LLM to use at a global level for agentic AI from the AI Agent Studio to help adjust the response quality to best fit your agentic workflows.  
Note:  
If you already have agents built and you change the global LLM, then you must test the agents after making the change. You can test the models in the skill kit without changing the LLM provider for all AI skills. Outside of the Skill kit, skills use whichever provider is set as default for the AI AGent SKills group.

Depending on your region, you may have to consent to using a different service provider.

## Procedure

1. Navigate to AllAI Agent StudioSettingsModel provider.
2. Select Configure to be redirected to AI Admin Hub.  
   You're directed to the AI Admin Hub Edit model provider page.

   For more information about managing a editing and customizing a model provider, see [Manage model providers](https://www.servicenow.com/docs/hR2eXtMPIcthQ4gj5DQPbg "Edit or customize the model provider for a skill or skill group at the instance level from the list of supported third-party model providers, including the default Now LLM Service. You can also review the model policy set by your organization, and view the change history here.").
3. In the Choose a default model provider field, select from the following choices.  
   * Now LLM Service
   * AWS Claude
   * Azure OpenAI
   * Google Gemini

   Note:  
   The new generative AI Config property records sys_generative_ai_config and sys_generative_ai_prompt_config have been introduced for the Azure OpenAI: gpt 5.4 model provider. Both the properties share a definition field that references the same sys_one_extend_capability_definition
   record, which identifies the LLM provider. The new prompt config records are set to true by default.
4. To use a different model provider:
   1. Navigate to the sys_generative_ai_prompt table.
   2. Filter and group by the relevant skill definition.
   3. Locate the record for the appropriate skill and provider.
   4. Set the preferred record as default.
   {#select-aia-llm-new__substeps_jqk_dt5_ljc}
5. Review the impacted AI agents.  
   Certain AI agents may require specific model providers. Select the AI agents tab in the Impact overview section to see which AI agents are affected by any changes to the model provider.
6. Select Save.

## Result

Your chosen LLM is used globally for all AI agents and agentic workflows.
