Amazon Bedrock supports structured output for all Anthropic Claude models at the bedrock-runtime and bedrock-mantle endpoints, according to AWS Machine Learning Blog.

According to the synopsis, the result may arrive as JSON conforming to the specified schema, with JSON Schema format and strict tool-use mode declared, without special parsing, retries, or post-processing.

Practical value—potentially more predictable integration of model outputs with application systems. However, the original package contains only metadata and a brief description, so details of implementation and limitations require verification against the full material.
