Amazon Nova Adds Built-In Web Grounding to Cut Hallucinations and Cite Sources
Amazon announced general availability of Web Grounding for its Amazon Nova foundation models on Amazon Bedrock, a built-in capability that lets Nova decide when to retrieve up-to-date public information during inference and then cite those sources.
The turnkey approach aims to reduce hallucinations and improve factual accuracy without requiring developers to build and maintain their own retrieval-augmented generation pipelines.
With Web Grounding enabled, Nova can automatically invoke real-time lookups based on prompt context and return responses that include attribution. In an example using the Bedrock Converse API and the Nova Premier model, developers declare a system tool named "nova_grounding" so the model can fetch current information when needed. The response can include reasoning traces indicating where external queries were made and a citations object listing sources; the raw external content remains hidden by design. Amazon positions this as useful for assistants that must deliver current product or service information, research scenarios that synthesize multiple sources, and customer support use cases that require verifiable answers.
Web Grounding is initially supported with Nova Premier, with support for additional Nova models planned. Availability starts in US East (N. Virginia), with US East (Ohio) and US West (Oregon) coming soon. The feature incurs additional cost; pricing details are on the Amazon Bedrock pricing page. Amazon also points to a self-paced workshop for developers who want to get hands-on with Nova models across text, image, and video use cases.
The announcement situates Web Grounding within Amazon's broader Nova initiative focused on reliability and accuracy. By integrating retrieval and citation directly into the model workflow, Amazon says developers can focus on application logic while relying on Nova to determine when grounding is necessary and to return answers with transparent source attribution.
