Anthropic has released Claude Sonnet 5.5, a more efficient model designed for focused coding and knowledge work on AWS. This new version is available on Amazon Bedrock and Claude Platform, with data staying within AWS infrastructure due to Regional data residency. Claude Sonnet 5.5 offers lower cost per task for most work, faster speeds, and polished outputs such as one-pagers, architecture diagrams, and summary slides.
It is ideal for continuous or large-scale workloads, including alert response, monitoring, SQL generation, UI/UX testing, and fast coding in IDEs with fixed spend caps. Claude Sonnet 5.5 excels at tasks with clear approaches, such as coding, spreadsheet edits, and routine document tasks, while Claude Opus 5.5 handles more judgment calls, like release debugging and code migrations.
To get started, users can access Claude Sonnet 5.5 through the Amazon Bedrock console or programmatically using the Anthropic Messages API, AWS CLI, or AWS SDK. Prerequisites include an active AWS account with Bedrock access, AWS CLI installed, Python 3.10+, Boto3, and IAM permissions. Claude Sonnet 5.5 is available globally through the Global CRIS inference profile on bedrock-runtime, with pricing details on Amazon Bedrock pricing.
