Claude Sonnet 5 is now available on AWS

AWS now offers Claude Sonnet 5 - Anthropic's most capable Sonnet model and the first Sonnet model of Anthropic’s latest generation - bringing top-tier intelligence at Sonnet pricing for coding, agents, and everyday professional work at scale.

Claude Sonnet 5 delivers strong performance across coding, professional work, and agentic tasks while maintaining the balance of capability, cost, and speed that teams get from Sonnet. For coding, it navigates large codebases, lands multi-file changes, and carries debugging and refactoring tasks through to completion with fewer rounds of correction. For agents, it calls tools precisely, holds state across many steps, and recovers from errors so more runs finish correctly the first time. For knowledge work, it builds spreadsheets, drafts documents, and turns unstructured material into structured analysis.

Customers have two ways to access Claude Sonnet 5: Amazon Bedrock and Claude Platform on AWS.

Amazon Bedrock keeps your data within AWS infrastructure and provides access to Claude Sonnet 5 through a unified service with AWS-managed features like Guardrails, Knowledge Bases, and regional data residency. To learn more, see the Amazon Bedrock documentation and regional availability.

Claude Platform on AWS gives you direct access to Anthropic's native platform experience and capabilities via the AWS Console. Build, test, and deploy with the same APIs, features, and console experience you'd get working with Anthropic directly, unified with AWS billing and authentication. To get started, see the Claude Platform on AWS documentation.
