Regarding Azure OpenAI (Japan East region): Can the o4-mini model (global-standard) be used?
The documentation seems to indicate it's not available, but Azure AI Foundry shows it as usable, and I've confirmed that requests go through.
I'm having trouble determining if it's in a GA (Generally Available) state and suitable for use in production applications. Any information you could provide would be greatly appreciated.

Hello !
Thank you for posting on Microsoft Learn.
Azure documentation may not be fully updated, or Japan East might be in a pre-GA or limited preview phase for o4-mini (Global Standard).
The ability to deploy and run successfully does not guarantee general availability (GA) or full compliance for production workloads, especially under stricter compliance regimes like GDPR, FISC, or APPI (important for Japan).
If you want to check if it is GA and production-ready, you can open an Azure support ticket and
ask explicitly whether o4-mini in Japan East is officially GA and compliant with regional processing requirements.
Meanwhile, you can use eastus2 instead if you need full compliance and certainty since it’s the only region marked as fully available for o4-mini Global Standard in the latest documentation.
