Claude Opus 5 Lands on AWS with Zero Data Retention
Anthropic's latest flagship model is now accessible through both Amazon Bedrock and Claude Platform on AWS, with data governance controls built in.
Is Claude Opus 5 available on AWS?
Yes. As of July 24, 2026, Claude Opus 5 is available on AWS through two distinct access paths: Amazon Bedrock and Claude Platform on AWS. Both options support zero data retention (ZDR), though the specifics of how that feature is enabled differ between the two.
Two access paths, different tradeoffs
Amazon Bedrock turns on ZDR by default for Claude Opus 5, meaning customer data stays within AWS infrastructure and is subject to regional data residency controls. Bedrock also layers in AWS-managed tooling, including Guardrails and Knowledge Bases, making it the more tightly integrated option for teams already operating within the AWS ecosystem.
Claude Platform on AWS takes a different approach: it delivers Anthropic's native platform experience, including the same APIs, features, and console environment available when working with Anthropic directly. Billing and authentication are unified with AWS, and ZDR is available on request rather than enabled by default.
What the model is built to do
Anthropologic positions Opus 5 around three capability areas. First, coding: the model is described as navigating and understanding codebases in a manner comparable to an experienced engineer, and producing production-quality output while adjusting its approach mid-task.
Second, long-running agentic work: the model is designed to operate autonomously for extended periods, including overnight runs, with the ability to route around obstacles and recover from errors without human intervention.
Third, complex document and analytical work: AWS's announcement highlights deeper reasoning over long documents and improved accuracy on complex analysis, with the largest stated gains in document-heavy enterprise contexts.

| API/console experience | AWS-native | Anthropic-native |
| Billing | AWS | AWS |
| Authentication | AWS | AWS |
Why the ZDR default matters
For regulated industries or teams with strict data handling policies, the distinction between "on by default" and "available on request" is meaningful. Bedrock's default ZDR posture removes a configuration step that could otherwise be overlooked, reducing the risk of data inadvertently persisting in ways that conflict with compliance requirements.
Teams that prefer working directly with Anthropic's tooling but want to consolidate their cloud vendor billing may find Claude Platform on AWS a practical middle ground, since it preserves the Anthropic-native developer experience while routing through AWS authentication and invoicing.
Getting started
AWS directs users to the Amazon Bedrock documentation for regional availability details and to the Claude Platform on AWS documentation for the Anthropic-native path. Both are accessible through the AWS Console.
