Accessing OpenAI GPT-5.6 models on Amazon Bedrock from Australia with global cross-Region inference

This article explains how to access OpenAI GPT-5.6 models on Amazon Bedrock from Australian regions with global cross-Region inference capabilities.

• Three GPT-5.6 models available: Sol for reasoning/coding, Terra for balanced performance, Luna for fast/affordable inference
• Access from Asia Pacific (Sydney) and Asia Pacific (Melbourne) regions with automatic routing to supported commercial AWS regions
• Supports OpenAI Responses API, Chat Completions API, and Amazon Bedrock Converse API with text and image inputs
• Prompt caching available in implicit and explicit modes to optimize inference costs
• Codex integration with OIDC-based authentication for enterprise identity providers
• Monitor usage via CloudWatch model invocation logging and Coding Agent Insights dashboard
• Quotas measured in requests per minute and tokens per minute with configurable burndown rates

Australian developers can now leverage advanced OpenAI models locally with flexible APIs, cost optimization, and comprehensive monitoring capabilities.
