Claude Opus 5.5 is now available on AWS
Anthropic's Claude Opus 5.5, first of the Claude 5.5 family, launches on Amazon Bedrock.
“Claude Opus 5.5 does more with fewer tokens than Claude Opus 5, and new pricing passes those gains straight to customers.”
Anthropic released Claude Opus 5.5, its most capable Opus model, on Amazon Bedrock and Claude Platform on AWS, featuring lower cost per task, always-on adaptive thinking, and clearer communication for long-running agentic work. It is also the first Opus model shipping with safety classifiers for biology, cybersecurity, and AI development, meaning more frequent refusals. This matters as a major frontier-model launch that expands enterprise access to advanced agentic coding and knowledge work.
