They are automatically tuned every three months.\n\nTuning keeps training optimal as data and end user behavior change throughout\nthe year. In addition, some internal upgrades can only be applied after the app\nhas been tuned.\n\nFor information about tuning costs, see [Pricing](/generative-ai-app-builder/pricing).\n\nManually restarting tuning triggers a one-time tune for your app. You might\nrestart tuning for your app when there is a significant change in your data\nstore (such as size increase or change in hierarchy) or events (such as\nbackfilling historical events or a change in data distribution after promoting\ncertain groups of content).\n\nTo restart tuning, follow these steps:\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 plan to tune.\n\n3. Go to the **Configurations** page and click the **Training** tab. This\n page shows the tuning status of your app.\n\n4. Click **Restart tuning**.\n\n Tuning takes 2-4 days, during which the app continues to work as usual.\n\nPause and resume training for a model\n-------------------------------------\n\nIf your app is active (not paused), training occurs at least once a\nweek, but no more often than once a day. For consistent retraining, make sure\nthat you upload user event data no more than 24 hours after the event occurs.\n\nYou can pause your model to stop retraining. You might want to do this if you\nhave imported bad data or to stay under the limit of 10 active recommendation\napps per project. If you have fewer than 10 active models, you can restart a\npaused app at any time.\n\nFor training cost details, see [Pricing](/generative-ai-app-builder/pricing).\n\nYou can start up to five media app creation, deletion, pause training, and\nresume training operations per minute.\n\nTo pause or resume training:\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 you plan to tune.\n\n3. Go to the **Configurations** page and click the **Training** tab. This\n page shows the training status of your app.\n\n4. To pause training, click *pause*\n **Pause training**.\n\n5. To resume a paused training, click *play_arrow*\n **Resume training**."]]
