Choose the language models for a Now Assist in Document Intelligence use case.

## Before you begin

* Set up a use case for the extract information from documents skill. For more information, see [Set up a use case for Now Assist in Document Intelligence](https://www.servicenow.com/docs/iqB4_8Mmo5GNmaBUq187~g "Create a use case record to define a document you want to process with Now Assist in Document Intelligence.").

## About this task

Language models are used to detect information in documents and make predictions for information extraction.

Third-party large language model (LLM) providers are available for Now Assist skills and AI agents in addition to Now LLM Service. For more information on LLMs in Now Assist, see [Manage AI models](https://www.servicenow.com/docs/HthEBS43hTzSOLxuj_BTlA "Access and select the LLM (large language model) provider used for various AI skills. The selection impacts all the skills within the capability.").

For each Now Assist in Document Intelligence use case, only one LLM can be enabled at a time. Now Assist employs the selected LLM when processing documents for the use case.

For image files that need optical character recognition (OCR) to detect the text in them, OCR models are used to support different language groups. The language selected during use case setup helps
the OCR model to detect text in the images.

## Procedure

1. Navigate to AllNow Assist AdminSkills.
2. In the workflow list, select Platform.
3. In the Platform skills list, find the applicable document intelligence skill and select Edit in the options menu ( ![Field options menu icon]()).
4. Select the use case you would like to configure.
5. Select the settings icon (![Use case settings icon]()).
6. Select the Manage LLMs screen.
7. Select the LLM that will make predictions for the documents processed with this use case.  
   For more information, see [Large language models used by Now Assist in Document Intelligence](https://www.servicenow.com/docs/Hsg6o0_gI82K1nRROD6GRw "Now Assist in Document Intelligence uses large language models (LLMs) to perform generative AI and agentic AI capabilities.").
8. **Optional:** Turn on image mode to process images more efficiently.  
   Image mode sends pages to the LLM as images to leverage the visual capability of the multimodal LLM as well as any of the languages supported by it.

   The image mode option is available when a multimodal LLM is selected.  
   Note:  
   Selecting image mode reduces the page count limit to 10 pages per file.
9. Select the Language of the files processed for the use case.  
   If the files contain multiple languages, select the primary language.

   For more information, see [Languages supported by Now Assist in Document Intelligence](https://www.servicenow.com/docs/kj0AeCvh6W0iq8dTQCTA4A "Now Assist in Document Intelligence supports text in multiple languages.").
10. Select Save.

## Result

The selected languages are enabled for the use case.
