In the **Prompt** (*Write your prompt here*) field, enter the following\n prompt:\n\n portrait of a french bulldog at the beach, 85mm f/2.8\n\n3. If not selected, in the **Model options** box in the **Parameters** panel,\n select `Imagen 3`.\n\n4. If not selected, in the **Aspect ratio** section in the **Parameters**\n panel, select `1:1`.\n\n5. In the **Number of results** section, change the **Number of results** to\n `2`.\n\n6.

To preserve the URLs that use the project ID, such as an `appspot.com` URL, delete selected resources inside the project instead of deleting the whole project.\n|\n|\n| If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects\n| can help you avoid exceeding project quota limits.\n1. In the Google Cloud console, go to the **Manage resources** page.\n\n [Go to Manage resources](https://console.cloud.google.com/iam-admin/projects)\n2. In the project list, select the project that you want to delete, and then click **Delete**.\n3. In the dialog, type the project ID, and then click **Shut down** to delete the project.\n\nWhat's next\n-----------\n\n- Learn about all image generative AI features in the [Imagen on Vertex AI overview](/vertex-ai/generative-ai/docs/image/overview).\n- Read [usage\n guidelines](/vertex-ai/generative-ai/docs/image/responsible-ai-imagen#imagen-guidelines) for Imagen on Vertex AI.\n- Explore more pretrained models in [Model Garden](/vertex-ai/generative-ai/docs/model-garden/explore-models).\n- Learn about [responsible AI best practices and Vertex AI's safety\n filters](/vertex-ai/generative-ai/docs/learn/responsible-ai)."]]
