Claude Opus 4.8 is now available on AWS

Claude Opus 4.8 is now available on Amazon Bedrock, as announced on the AWS ML Blog. This latest iteration of Anthropic's flagship model brings enhancements in reasoning, coding, and tool use, making it particularly suited for agentic systems and production inference workloads. The model retains a 200K context window and is available in the US East (N. Virginia) and US West (Oregon) AWS regions. Pricing follows the existing Opus tier: $15 per million input tokens and $75 per million output tokens. The post provides practical guidance for AI engineers integrating the model, including best practices for prompt engineering and function calling. Early benchmarks suggest improvements in complex multi-step reasoning tasks and code generation accuracy. This release underscores Anthropic's focus on enterprise-grade reliability and safety, with the model undergoing rigorous evaluation for harmful outputs. Developers using Bedrock can immediately switch to Opus 4.8 via the AWS console or API, with no additional setup required.
