Amazon Web Services announced on September 30 that Amazon Bedrock is adding in-region support for Anthropic's Claude Opus 5.5 and Claude Sonnet 5 models in the UK London region.[^1]

Customers can access these models through the Amazon Bedrock console playground or programmatically using the Anthropic Messages API, InvokeModel API, and Converse API.[^2] The bedrock-runtime endpoint in the London (eu-west-2) Region supports in-region inference for Claude Opus 5.5 and Claude Sonnet 5.[^3]

The bedrock-runtime endpoint supports Anthropic's Messages API and the Amazon Bedrock InvokeModel and Converse APIs, along with Amazon Bedrock features such as Amazon Bedrock Guardrails and intelligent prompt routing.[^4] This rollout follows earlier support for Claude Opus 5 and Claude Sonnet 5 in South Korea and Singapore.[^5][^6]
