# Use your AI request block to interact with an AI model

When you [create an AI request block](/flows/build-flows/ai/ai-request-blocks/create/) in Postman Flows, you select an AI request for it. You can use the AI request to control how your AI request block interacts with the model in your flow.

## Interact with the AI model

To interact with the AI model, do the following:

1. Open a flow and choose an existing AI request block or [create a new one](/flows/build-flows/ai/ai-request-blocks/create/).
2. Click ![Edit icon](https://assets.postman.com/postman-docs/aether-icons/action-edit-stroke.svg#icon) next to the AI model's name. Postman opens the AI request in a new tab.
3. Enter or edit your user prompt and (optional) enter or edit your system prompt.
4. (Optional) Configure or edit **Authorization** details or **Settings** as described in [Manage your AI request settings](#manage-your-ai-request-settings).
5. Click **Save**.

Your AI request block uses your last saved user and system prompts to interact with the model. To learn more, see [Use your AI request to interact with an AI model](/docs/use/send-requests/protocols/ai-requests/interact/).

## Manage your AI request settings

To manage your AI request settings, do the following:

1. Choose an existing AI request block or [create a new one](/flows/build-flows/ai/ai-request-blocks/create/).
2. Click ![Edit icon](https://assets.postman.com/postman-docs/aether-icons/action-edit-stroke.svg#icon) next to the AI model's name. Postman opens the AI request in a new tab.
3. To edit your request authorization details, open the **Authorization** tab and [edit your request authorization details](/docs/use/send-requests/protocols/ai-requests/manage/#edit-your-request-authorization-details).
4. To adjust your request settings, open the **Settings** tab and [adjust your request settings](/docs/use/send-requests/protocols/ai-requests/manage/#adjust-your-request-settings).

Your AI request block uses your last saved request settings to interact with the model. To learn more, see [Manage your AI request settings](/docs/use/send-requests/protocols/ai-requests/manage/).
