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

What changed

Source summary

AWS expanded OpenAI model availability in Australia via Amazon Bedrock's new global cross-Region inference, giving Australian applications access to GPT-5.6 Sol, Terra and Luna from both Sydney and Melbourne regions, with requests automatically routed to supported AWS regions without applications having to manage the destination themselves.

Why it matters to your work

Practical interpretation

Mainly relevant if your organisation runs AI workloads on AWS - Australian businesses can now call OpenAI's latest models through local AWS infrastructure with better capacity and reliability, with no extra setup needed to pick a region.

When this could help

Running OpenAI workloads from Australia where latency or data residency matters, or evaluating Bedrock's cross-region inference profiles for resilience.

OpenAI models on Amazon Bedrock are now available in Sydney (ap-southeast-2) and Melbourne (ap-southeast-4), with global inference profiles for automatic cross-region routing, 1M-token context, SigV4 authentication, and Codex CLI alpha support — all under existing AWS security and compliance controls.

What to check

• Codex CLI is in alpha — not production-ready. Source ↗
• Pricing follows Bedrock's regional rates, not OpenAI's direct API pricing. Source ↗
