Amazon Bedrock now supports structured outputs to AWS GovCloud (US) Regions

Amazon Bedrock is a fully managed service that provides access to a wide selection of high-performing foundation models from leading AI companies through a single API. Today, Amazon Bedrock expands structured outputs support to AWS GovCloud (US) Regions. Structured outputs enables foundation models to return consistent, schema-compliant, machine-readable responses—making it well-suited for government and regulated workloads that must meet strict compliance and data handling requirements.

Structured outputs helps with common production tasks, such as extracting key fields and powering workflows that use APIs or tools, where even minor formatting errors can break downstream systems. By ensuring schema compliance, it reduces the need for custom validation logic and lowers operational overhead by minimizing failed requests and retries—so you can confidently deploy AI applications that require predictable, machine-readable outputs. You can use structured outputs either by defining a JSON schema that describes your desired response format or by using strict tool definitions to ensure a model's tool calls match your specifications.

Structured outputs is now generally available in all commercial AWS and AWS GovCloud (US) Regions where Amazon Bedrock is supported. To learn more about structured outputs and the supported models, visit the Amazon Bedrock documentation.
