AWS – Claude Opus 4.5 now available in Amazon Bedrock

Customers can now use Claude Opus 4.5 in Amazon Bedrock, a fully managed service that offers a choice of high-performing foundation models from leading AI companies. Opus 4.5 is Anthropic’s newest model, setting new standards across coding, agentic workflows, computer use, and office tasks while making Opus-level intelligence accessible at one-third the cost.

Opus 4.5 excels at professional software engineering tasks, achieving state-of-the-art performance on SWE-bench. The model handles ambiguity, reasons about tradeoffs and can figure out fixes for bugs that require reasoning across multiple systems. It can help transform multi-day team development projects into hours-long tasks with improved multilingual coding capabilities. This generation of Claude spans the full development lifecycle: Opus 4.5 for production code and lead agents, Sonnet 4.5 for rapid iteration and scaled user experiences, Haiku 4.5 for sub-agents and free-tier products.

Beyond coding, the model powers agents that produce documents, spreadsheets, and presentations with consistency, professional polish, and domain awareness, making it ideal for finance and other precision-critical verticals. As Anthropic’s best vision model yet, it unlocks workflows that depend on complex visual interpretation and multi-step navigation. Through the Amazon Bedrock API, Opus 4.5 introduces two new capabilities: tool search and tool use examples. Together, these updates enable Claude to navigate large tool libraries and accurately execute complex tasks. A new effort parameter, available in beta, lets you control how much effort Claude allocates across thinking, tool calls, and responses to balance performance with latency, and cost.

Claude Opus 4.5 is now available in Amazon Bedrock via global cross region inference in multiple locations. For the full list of available regions, refer to the documentation. To get started with the model in Amazon Bedrock, read the launch blog or visit the Amazon Bedrock console.
