Amazon Bedrock expanded its capabilities by supporting OpenAI GPT-5.6 models, Terra and Luna, accessible via Responses, Converse, and Chat Completions APIs in the AWS GovCloud (US) environment. This integration allows users to leverage native OpenAI APIs through Bedrock's runtime endpoint, enabling consistent account-level controls including detailed logging, metrics, and cost tracking.
Additionally, Cross-Region Inference was introduced, routing inference requests across AWS GovCloud (US) Regions for higher throughput and increased redundancy. This feature maintains US data sovereignty while scaling capacity during demand spikes, without requiring users to manage multi-region resources manually. Availability covers all AWS Regions where OpenAI models on Bedrock are offered.
