Introducing cross-Region inference for OpenAI GPT-5.6 models on Amazon Bedrock
Amazon Bedrock now offers OpenAI GPT-5.6 models with cross-Region inference across 25+ AWS Regions
“By allowing requests to draw on a broader pool of compute rather than being bound to one Region's available capacity, it improves throughput and helps maintain consistent performance under load.”
AWS and OpenAI have deepened their partnership by making GPT-5.6 models (Sol, Terra, Luna variants) available via cross-Region inference on Amazon Bedrock across more than 25 Regions. The launch supports geographic and global inference profiles, a 1M token context window, reasoning mode, and compatibility with both OpenAI and Bedrock APIs. This matters because it signals continued AWS-OpenAI infrastructure collaboration competing with Google/Azure cloud AI distribution.
