If your access request to Azure OpenAI service doesn't match the [acceptance criteria](https://learn.microsoft.com/legal/cognitive-services/openai/limited-access?context=%2Fazure%2Fcognitive-services%2Fopenai%2Fcontext%2Fcontext), you can use [OpenAI public API](https://platform.openai.com/docs/api-reference/introduction) instead. Learn [how to switch to an OpenAI instance](docs/deploy_existing.md#openaicom-openai).
 * **Azure account permissions**:

If you don't have subscription-level permissions, you must be granted [RBAC](https://learn.microsoft.com/azure/role-based-access-control/built-in-roles#role-based-access-control-administrator-preview) for an existing resource group and [deploy to that existing group](docs/deploy_existing.md#existing-resource-group).

 1. Run `azd up` - This will provision Azure resources and deploy this sample to those resources, including building the search index based on the files found in the `./data` folder.
     * **Important**: Beware that the resources created by this command will incur immediate costs, primarily from the AI Search resource. These resources may accrue costs even if you interrupt the command before it is fully executed. You can run `azd down` or delete the resources manually to avoid unnecessary spending.
     * You will be prompted to select two locations, one for the majority of resources and one for the OpenAI resource, which is currently a short list. That location list is based on the [OpenAI model availability table](https://learn.microsoft.com/azure/cognitive-services/openai/concepts/models#model-summary-table-and-region-availability) and may become outdated as availability changes.
