This feature is available only for media\nrecommendations, not custom search and recommendations.\n\nGenerally, diversification reduces the likelihood that similar content is\nshown in a recommendation panel, at the risk of removing some good\nrecommendations.\n\nDiversification is set on the serving config level. You can have multiple\nserving configs per media recommendations app, each with a different\ndiversification setting. For more about serving configs, see\n[Create and manage media serving configs](/generative-ai-app-builder/docs/serving-configs).\n\nTwo types of diversification are available: rule-based diversity and data-driven\ndiversity.\n\nRule-based diversity\n--------------------\n\nRule-based diversity relies on the categories that are uploaded with your\ncontent. Use rule-based diversity to recommend content from a variety of\ncategories. Diversification is configured by level, with higher levels of\ndiversification causing fewer items to be displayed per category. This\ndiversification type works best if your content has high-quality categories.\n\nIn general, setting rule-based diversity and using filter recommendations is not\nadvised. For more information, see [Filters and diversification\nsettings](/generative-ai-app-builder/docs/filter-recommendations#filter-diversification-media).\n\nData-driven diversity\n---------------------\n\nUse data-driven diversity to produce recommendation results that balance\nrelevance and diversity. Data-driven diversity learns from content metadata such\nas titles or categories. Instead of relying on words from a title or category,\ndata-driven diversity uses semantic similarity to produce better-performing\ndiversification.\n\nDiversify recommendations\n-------------------------\n\nTo diversify your media recommendations:\n\n1. In the Google Cloud console, go to the **AI Applications** page.\n\n [AI Applications](https://console.cloud.google.com/gen-app-builder/start)\n2. Click the name of the app that you want to configure recommendations for.\n\n3. Go to the **Configurations** \\\u003e **Serving** tab.\n\n4. If you have more than one serving config, select the serving config that you\n plan to set diversification for.\n\n5. In the **Result diversification** section, choose how to diversify your\n recommendations in the **Diversification type** field.\n\n6. Turn on the **Enable diversification level** toggle to see the\n available diversification levels.\n\n7. Select a diversification level for your recommendations.\n\n8. Click **Save and publish**."]]
