You can use AutoML to quickly prototype models and\n explore new datasets before investing in development. For example, you can use\n it to learn which features are best for a given dataset.\n\n- With [custom training](/vertex-ai/docs/training/overview) you can create a training\n application optimized for your\n targeted outcome. You have complete control over training application\n functionality. Namely, you can target any objective, use any algorithm, develop\n your own loss functions or metrics, or do any other customization.\n\n- With [Ray on Vertex AI](/vertex-ai/docs/open-source/ray-on-vertex-ai/overview) you can use\n [Ray](https://docs.ray.io/en/latest/)'s distributed computing\n framework on Google Cloud infrastructure. Ray on Vertex AI provides\n a managed environment with configurable compute resources, integration\n with services like Vertex AI Inference and BigQuery, and\n flexible networking options for developing and running distributed workloads.\n\n- Using [BigQuery](/vertex-ai/docs/beginner/bqml), you can train models\n using your BigQuery data directly\n in BigQuery. Using SQL commands, you can quickly create a model and\n use it to get batch inferences.\n\nTo compare the different functionality and expertise required for each service,\nreview the following table.\n\nWhat's next\n-----------\n\n- Choose an [introductory tutorial](/vertex-ai/docs/tutorials) to get started with Vertex AI Training.\n- Learn more about [training an AutoML model](/vertex-ai/docs/training-overview#automl).\n- Learn about [creating a custom training job using Python](/vertex-ai/docs/training/create-custom-job).\n- Learn more about [Ray on Vertex AI](/vertex-ai/docs/open-source/ray-on-vertex-ai/overview)."]]
