Using GPT Models in Your App Without Sending Your Data to OpenAI
Azure OpenAI, now part of Microsoft Foundry, gives you access to OpenAI models (the GPT-5 family, image and transcription models), hosted by Microsoft in Azure and attached to your subscription.

Want to build GPT models into your enterprise applications? Azure OpenAI gives you access to OpenAI models under Microsoft Azure's security and compliance commitments.
Why Azure OpenAI instead of direct OpenAI?
According to Microsoft's documentation, your prompts and completions are neither shared with OpenAI nor used to train the models. Content goes through configurable filters, the service falls under Azure certifications (ISO, SOC) and Microsoft's GDPR commitments, and technical support runs through your Azure support plan. The API is very close to OpenAI's, with Azure governance on top.
Available models and use cases
The GPT-5 family for text generation and image analysis, gpt-image models for image generation, audio transcription models, embedding models for semantic search. The catalogue changes fast: GPT-4, GPT-4 Vision and DALL-E 3 no longer appear in Microsoft's schedule, and Whisper is due to retire on 15 December 2026 (schedule checked on 26 October 2026).
RAG architecture with your data
The RAG pattern allows the model to respond based on your enterprise documents. Azure AI Search indexes your content, the model generates contextualized responses.
Deployment and quotas
Deploy your models in the Azure regions where they are available, or as a Data Zone deployment to keep processing within the European Union. Manage token quotas. Use content filters. Monitor via Azure Monitor.
Summary
Azure OpenAI makes generative AI accessible to enterprises within Azure's security and compliance framework. Helion Cloud designs and deploys AI solutions on Azure.
