Introducing Claude Fable 5.1 on AWS
Claude Fable 5.1 is now available on Amazon Bedrock and Claude Platform on AWS. This post covers Claude Fable 5.1's improvements, the Enterprise Frontier Safeguards for keeping your data in a cloud environment you control, and how to start building with the model on Amazon Bedrock.
Anthropic has unveiled Claude Fable 5.1 on Amazon Bedrock and Claude Platform on AWS. This latest version boasts frontier intelligence, making it suitable for intricate tasks in coding, scientific research, and enterprise workflows. As a Covered Model, Claude Fable 5.1 involves additional data retention, safety review, and access policies across all platforms. Amazon Bedrock users must adhere to data retention policies, retaining prompts and outputs for potential human review within AWS boundaries.
Enterprise Frontier Safeguards (EFS) partner between AWS and Anthropic offers an alternative for customers who wish to deploy Anthropic’s most capable models while retaining control over their data in cloud infrastructure. Users can access Claude Fable 5.1 with zero data retention (ZDR) on Amazon Bedrock and Claude Platform on AWS.
However, ZDR availability is restricted to internal use through December 31, 2026. Future updates will allow users to retain prompts and outputs within their AWS accounts, utilizing encryption keys, access policies, and audit logging. Safety monitoring for EFS users will only involve automated reviews, skipping human review.
To start using Claude Fable 5.1 on Amazon Bedrock, users need an active AWS account with Amazon Bedrock access and AWS Command Line Interface (AWS CLI) installed. Python 3.10+ and Boto3 must be ready. Upon accessing the Amazon Bedrock console, users can select Fable 5.1 in the Test Playground or programmatically invoke the model using the Anthropic Messages API with bedrock-runtime.
AWS provides a sample Boto3 code snippet demonstrating how to invoke Claude Fable 5.1. Claude Fable 5.1 is currently accessible through the US Geo CRIS (us.) and Global CRIS (global.) inference profiles in AWS, as well as AWS GovCloud (US). Pricing details are available on Amazon Bedrock pricing, while supported regions are listed in the Bedrock documentation.
