# Use a deployment for on-demand inference


After you deploy your custom model for on-demand inference, you can use it to generate responses by making inference requests. For `InvokeModel` or `Converse` operations, you use the deployment Amazon Resource Name (ARN) as the `modelId`.

For information about making inference requests, see the following topics:
