Data residency and AXT security controls aren't\n| supported.\n\nThis page describes the Vertex AI RAG Engine pricing and billing based on the Vertex AI RAG Engine components you use, such as models, reranking, and vector storage.\n\nFor more information, see the [Vertex AI RAG Engine overview](/vertex-ai/generative-ai/docs/rag-engine/rag-overview) page.\n\nPricing and billing\n-------------------\n\nVertex AI RAG Engine is free to use. However, if you configure\nVertex AI RAG Engine components, the billing might be affected.\n\nThis table explains how billing works when you use the RAG components.\n\nWhat's next\n-----------\n\n- To learn how to use the Vertex AI SDK to run Vertex AI RAG Engine tasks, see [RAG quickstart for\n Python](/vertex-ai/generative-ai/docs/rag-quickstart).\n- To learn about grounding, see [Grounding\n overview](/vertex-ai/generative-ai/docs/grounding/overview).\n- To learn more about the responses from RAG, see [Retrieval and Generation Output of Vertex AI RAG Engine](/vertex-ai/generative-ai/docs/model-reference/rag-output-explained).\n- To learn about the RAG architecture:\n - [Infrastructure for a RAG-capable generative AI application using Vertex AI and Vector Search](/architecture/gen-ai-rag-vertex-ai-vector-search)\n - [Infrastructure for a RAG-capable generative AI application using Vertex AI and AlloyDB for PostgreSQL](/architecture/rag-capable-gen-ai-app-using-vertex-ai)."]]
