AWS bedrock documentation change

Service: bedrock · 2026-03-13 · Documentation low

File: bedrock/latest/userguide/knowledge-base-build-graphs-build.md

Summary

Added documentation about supported foundation models for building knowledge base graphs, including Claude 3 Haiku, Claude Haiku 4.5, and Amazon Nova family models. Also added information about cross-Region inference profiles and data storage implications.

Security assessment

This change adds information about supported models and cross-Region inference profiles. While it mentions data storage location (data stored only in source Region), this is not addressing a specific security vulnerability or weakness. It's general documentation about feature capabilities and regional data handling.

+For the `modelArn` used to build the graph from your documents, you can use Claude 3 Haiku (as shown in the preceding example), Claude Haiku 4.5, and the Amazon Nova family (including Nova 2 and Nova models with text input modality). To see the foundation models available in your Region, see [Supported foundation models in Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/models-supported.html).

+###### Note
+
+Some models are supported only through cross-Region inference profiles. When you invoke a cross-Region inference profile in Amazon Bedrock, your request and data to be ingested originates from a source Region and is automatically routed to one of the destination Regions defined in that profile, optimizing for performance. The destination Regions for Global cross-Region inference profiles include all commercial Regions. For example, you might specify the `modelArn` for a us-based cross-Region call from the us-west-2 Region using the format `arn:aws:bedrock:us-west-2:`account-id`:inference-profile/us.anthropic.claude-haiku-4-5-20251001-v1:0`.

+To see the policy requirements for your role to use inference profiles, see [Prerequisites for cross-Region inference profiles](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles-prereq.html). For guidance on how to use inference profiles to select source and destination Regions, see [Supported Regions and models for inference profiles](https://docs.aws.amazon.com/bedrock/latest/userguide/inference-profiles-support.html). Your data is stored only in your source Region corresponding to the Amazon Bedrock knowledge base and Amazon Neptune Analytics instance. The destination Region is used for inference only.
