Choose which LLM you want to use by default to generate descriptions for inputs, outputs, and skills for conversational actions.

## About this task

In the conversational actions settings, you can use generative AI to generate descriptions for skills, inputs, and outputs of a conversational action. You can select a default LLM to generate these descriptions out of any of the following preconfigured LLMs:

-   Anthropic Claude
-   Azure OpenAI
-   Google Gemini
-   Now LLM

**Note:** This configuration affects only the capability to generate the descriptions.

## Procedure

1.  Select **All**.

2.  In the **Filter** search box, enter `sys_one_extend_capability.list`.

3.  In the OneExtend Capabilities list, search for the application `Conversational subflows and actions`.
