Amazon Expands Web Search Capabilities on Amazon Bedrock

Amazon has expanded its Web Search capabilities on Amazon Bedrock, allowing developers to ground their AI models in current web knowledge. This feature is designed for use with Amazon Bedrock model inference and provides a multi-source grounding approach that combines Amazon's web index with a built-in knowledge graph.

The new Web Search tool performs semantic snippet extraction, pulling relevant passages from web pages and returning them in a form optimized for the model's context window. This helps to reduce factual inaccuracies and hallucinations, as the model can rely on current information rather than its training data alone.

To enable Web Search, developers need to add a single parameter to their API call using the OpenAI Responses API. The tool is available for use with OpenAI models served through Amazon Bedrock's next-generation inference engine.
