# Configure multimodal captioning for AI Search

# Configure multimodal captioning for AI Search {#ariaid-title1}

![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Use the AI Search Admin console to select the visual language model (VLM) provider and model for multimodal captioning.

## Before you begin

* The Platform Multimodal Service plugin (com.glide.platform_mm_service) must be installed on your instance. If the plugin is not installed, multimodal captioning options will not appear in the AI Search Admin console. For more information, see [Activate the Platform Multimodal Service plugin](https://servicenow-prod.fluidtopics.net/Aps2A3ZsA_gtaZTILcqu2w "Enable automatic generation of searchable descriptive captions for images, tables, charts, and other visual elements found in indexed attachments.").
* Role required: ais_admin

## About this task

When multimodal captioning is activated, attachments retrieved from supported sources are automatically analyzed and given descriptive captions, making visual content, such as images, discoverable through text-based search.
You can specify the VLM provider and model to use when generating captions.

## Procedure

1. Navigate to AllAI Search AdminAI Search Admin Home.
2. Select System Properties.
3. In the Multimodal captioning section, select a Provider from the drop-down list.  
   A provider is the VLM you want to use for captioning.  
   Note:  
   If your preferred provider is not listed, use the AI Control Tower (AICT) to configure approved third-party LLMs. For more information, see [Configure third-party LLMs using AI Control Tower](https://www.servicenow.com/docs/access?context=configure-third-party-llms-using-ai-control-tower&version=australia&pubname=australia-intelligent-experiences&ft:locale=en-US). NowLLM doesn't support this feature.  
   The corresponding Model options appear.
4. Select a Model from the drop-down list.  
   A model is a specific version of AI offered by the provider.
5. Select Save.

## Result

Changes to the provider and model take effect immediately for multimodal captioning.

## What to do next

AI Search administrators have additional configuration options available, as follows:

* AI Search administrators can activate multimodal captioning for individual AI Search indexed sources. For details on this procedure, see [Activate multimodal captioning for attachments from an indexed source](https://servicenow-prod.fluidtopics.net/Krl_JAnqLi2PGly9iLmPPg "Generate descriptive captions for images, tables, charts, and other visual elements in attachments from records in an indexed source table. You can find these attachments by searching for terms from their generated captions.").
* Connector administrators can activate multimodal captioning in the crawl settings for an external content connector. To learn about configuring crawl settings for external content connectors, see [Configuring crawl settings for external content connectors](https://servicenow-prod.fluidtopics.net/GvhDZ6doCt4nrRPDkPNVAQ "Connector administrators can configure crawl settings for each external content connector, such as which source system locations it crawls and which types of content it sends to AI Search for indexing.").
