AWS introduces built-in web search for Amazon Bedrock model grounding

AWS has introduced Web Search for Amazon Bedrock, enabling foundation models to retrieve current web information with citations through a built-in, server-side capability using a single API call.

AWS has launched Web Search for Amazon Bedrock, a built-in capability that enables supported foundation models to ground responses using up-to-date web information without integrating third-party search services.

Developers can enable the feature through a single parameter in the OpenAI-compatible Responses API, while Amazon Bedrock manages query generation, retrieval, citation handling, and orchestration entirely on the server side.

The service returns structured citations, uses Amazon's continuously refreshed web index for semantic retrieval, and supports enterprise security by keeping processing within the AWS environment. The feature is generally available in select AWS Regions for supported OpenAI models on Amazon Bedrock.
