Introducing Claude Sonnet 5.5 on AWS
Claude Sonnet 5.5 launches on Amazon Bedrock with lower cost and faster speed for coding workloads
“Claude Sonnet 5.5 takes the work where the approach is already clear and what's left is to execute it quickly, with a lower cost per task (than Opus 5.5) for most work at faster speed.”
Anthropic's Claude Sonnet 5.5 is now available on Amazon Bedrock and Claude Platform on AWS, offering improved coding and document generation capabilities at lower cost per task than Opus 5.5. The launch introduces a two-tier model pairing strategy — Opus 5.5 for complex judgment calls, Sonnet 5.5 for well-scoped execution tasks — targeting enterprise-scale continuous workloads. The AWS integration preserves data residency and hooks into existing IAM, CloudTrail, and CloudWatch controls, lowering the barrier for enterprise adoption.
