Amazon Bedrock Structured Outputs

Amazon Bedrock now supports structured outputs, enabling consistent, machine-readable responses from foundation models that adhere to your defined JSON schemas. This feature simplifies production workflows by ensuring responses match your specified format, reducing the need for custom validation logic and operational overhead.

What to do

  • Define a JSON schema for your desired response format.
  • Use strict tool definitions to match model tool calls with your specifications.
  • Deploy AI applications with predictable, machine-readable outputs.

Structured outputs are available for Anthropic Claude 4.5 models and select open-weight models across various APIs in all commercial AWS Regions where Amazon Bedrock is supported. For more information, visit the Amazon Bedrock documentation.
