Artificial Intelligence
Today, we’re excited to announce the availability of Anthropic’s most advanced Sonnet model, Claude Sonnet 5, on Amazon Bedrock and Claude Platform on AWS. Claude Sonnet 5 is the first Sonnet model of Anthropic’s latest generation and represents a meaningful step forward. It delivers top-tier intelligence at Sonnet pricing for coding, agents, and everyday professional work at scale. With Claude Sonnet 5 on Amazon Bedrock you can build within your existing AWS environment, maintain enterprise security and regional data residency, and scale inference. Claude Sonnet 5 is also available through Claude Platform on AWS, giving you access to Anthropic’s native platform experience and capabilities via the AWS Management 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.
This post covers the improvements in Sonnet 5 and practical guidance for AI engineers integrating the model into agentic systems and production inference workloads on Amazon Bedrock. See the documentation for Claude Platform on AWS.
What makes Claude Sonnet 5 different
Claude Sonnet 5 shows stronger performance across coding, agentic tasks, and professional work. Claude Sonnet 5 brings near-Opus intelligence while maintaining the same balance of capability, cost, and speed, so teams can rely on Sonnet for everyday tasks at scale. Use Claude Sonnet 5 when you need strong reasoning, coding, and agentic reliability at scale without Opus-tier pricing. Use Claude Opus when your task demands the highest reasoning that justifies the cost premium. Sonnet 5 can hold a plan across stages, track what it has done and what remains, and resolve issues with fewer rounds of correction. This leads to more predictable behavior at scale.
