The service now routes GPT-5.6 Sol, Terra, and Luna requests across 25 AWS Regions using geographic and global profiles.

Amazon Bedrock now offers OpenAI GPT-5.6 models in more than 25 AWS Regions with cross-Region inference. The three general-purpose variants, Sol, Terra, and Luna, support geographic and global inference profiles.

Cross-Region inference works through inference profiles that define a model and the AWS Regions Amazon Bedrock can route a request to. A geographic profile uses a prefix such as us. to keep processing within that geography, and a global profile uses the prefix global to route across all supported commercial AWS Regions.

For builders, cross-Region inference acts primarily as a capacity mechanism. Requests can draw on a broader pool of compute instead of a single Region’s available capacity, which improves throughput and maintains consistent performance under load. All three GPT-5.6 variants accept text and image inputs, return text, and support reasoning mode, server-side tool calling, and prompt caching.

Developers can call GPT-5.6 through the OpenAI Responses API, the OpenAI Chat Completions API, and the Amazon Bedrock Converse API. Streaming is available with stream=True and ConverseStream. Organizations with data residency requirements can use geographic inference profiles to scale across Regions while keeping data within a single geography.

What matters

• Amazon Bedrock now provides OpenAI GPT-5.6 Sol, Terra, and Luna in more than 25 AWS Regions.
• Cross-Region inference routes requests to compute in destination Regions within a defined geography.
• Watch for global profiles that route across all commercial AWS Regions using real-time capacity.

Why it matters

Watch for global profiles that route across all commercial AWS Regions using real-time capacity.
