Amazon Bedrock Supports Claude Structured Outputs
Understand the story
On October 20, 2026, the AWS Machine Learning Blog announced that Amazon Bedrock has officially launched a structured output feature for Anthropic Claude models. The feature covers all Claude models and is available on both the bedrock-runtime and bedrock-mantle endpoints. Through a constrained decoding mechanism, the model is forced to conform to the specified JSON schema during generation, so developers no longer need to write their own custom parsing and retry logic. This update aims to streamline the workflow for developers using Claude on Bedrock for structured data generation. The event is still at the feature release stage, with no follow-up usage feedback or issue reports yet.
