Access OpenAI GPT models on Amazon Bedrock from Canada with cross-Region inference

Amazon Bedrock customers in Canada can now reach OpenAI's GPT-5.6, GPT-6 and GPT-6.1 models through cross-Region inference, which routes requests from a Canadian source Region to other Regions for processing.

• The models are available from the Canada (Central) and Canada West (Calgary) Regions, and inference stays within North America under the US geographic profile.
• Cross-Region inference is a capacity mechanism: the application calls the Bedrock Runtime endpoint in its own Region and Bedrock routes the request to a supported destination Region, drawing on a broader capacity pool to sustain throughput during demand spikes.
• The models accept text and image inputs, return text, and support a 1-million-token context window, reasoning mode, tool calling and prompt caching.
• They can be called through the OpenAI Responses API, the OpenAI Chat Completions API and the Amazon Bedrock Converse API on the bedrock-runtime endpoint.
• Two profile types are offered from Canada: the US geographic profile, which keeps processing in Canada and the US, and the global profile, which routes to supported commercial AWS Regions where the model is deployed.
• The global profile for the GPT-5.6 models is available only from ca-central-1, so ca-west-1 users must use the US geographic profile for those models.
