AWS launches Claude Sonnet 5.5, offering improved efficiency and cost-effectiveness for coding and knowledge tasks.
On September 28, 2026, Amazon Web Services (AWS) announced the availability of Claude Sonnet 5.5, the latest iteration in Anthropic's Sonnet series, designed to enhance coding and knowledge work efficiency. This new model is accessible through Amazon Bedrock and the Claude Platform on AWS.
Claude Sonnet 5.5 builds upon its predecessor by offering more efficient performance, particularly in coding tasks. It excels in executing well-defined coding assignments, such as developing and refining features within a single session, and verifying outputs against specified requirements. Additionally, the model is adept at producing polished knowledge work, including one-page summaries, diagrams, and document edits.
Users can access Claude Sonnet 5.5 via two primary channels:
1. **Amazon Bedrock**: This service integrates Sonnet's capabilities within the AWS infrastructure, ensuring regional data residency and providing features like Guardrails and Knowledge Bases. Detailed information is available in the Amazon Bedrock documentation.
2. **Claude Platform on AWS**: This platform offers direct access to Anthropic's native tools and features through the AWS Console, allowing for seamless building, testing, and deployment experiences. Further details can be found in the Claude Platform on AWS documentation.
The introduction of Claude Sonnet 5.5 signifies AWS's commitment to providing advanced AI tools that cater to the evolving needs of developers and enterprises, emphasizing efficiency and cost-effectiveness in professional tasks.
