Azure OpenAI
🌍 International
Azure OpenAI is Microsoft's enterprise Azure-hosted OpenAI API option for teams that need Azure governance, procurement, networking, compliance, and regional controls. It is not a typical free API; the buying decision depends on access approval, model-region availability, deployment names, RPM/TPM quota, content safety policy, and cost controls.
