Structured outputs for Anthropic Claude models on Amazon Bedrock.

AWS Machine Learning BlogCompany announcement·
AI brief

Amazon Bedrock now supports structured outputs for all Anthropic Claude models on the bedrock-runtime and bedrock-mantle endpoints, returning schema-compliant JSON without custom parsing or retry logic.

Why it matters: Developers using Claude on Bedrock can get JSON matching a defined schema directly instead of post-processing model responses.
