Amazon S3 Vectors reduces query charges by up to 80% for large vector indexes
Amazon S3 Vectors has reduced data processed charges for queries on vector indexes with over 10 million vectors by up to 80%. This reduction lowers costs for customers running similarity search across large-scale AI, RAG, and semantic search workloads. The new pricing applies automatically with no application changes required. While this change reduces costs for large indexes, we continue to recommend distributing vectors across multiple indexes for improved query performance. S3 Vectors query pricing reductions are effective today in all AWS Regions where S3 Vectors is available. For updated
The continuous growth of large-scale AI applications, retrieval-augmented generation (RAG), and semantic search workloads drives the need for more cost-effective vector database infrastructure on cloud platforms.
Lowering the cost of vector index queries by up to 80% directly addresses a key economic barrier to scaling AI and search applications, making advanced AI more accessible and financially viable for a broader range of enterprises.
The economic model for deploying and scaling large vector indexes dramatically improves, encouraging greater adoption of sophisticated AI architectures that rely on vector similarity search capabilities.

Immediate cost savings for existing large-scale S3 Vectors users and reduced friction for new deployments.
Accelerated adoption and scaling of AI applications, especially those requiring extensive similarity search over large datasets, now that a significant cost component is mitigated.
Increased cloud dependency for AI infrastructure as public cloud providers like AWS continue to optimize the underlying economic layers for AI workloads, potentially centralizing more AI compute and storage.
