Azure OpenAI vs OpenAI: both give you access to OpenAI models, but through different platforms. The OpenAI API is provided directly by OpenAI. Azure OpenAI is offered by Microsoft inside Azure, with enterprise controls such as Microsoft Entra ID authentication, private endpoints, virtual network integration, regional deployment choices, Azure Policy and Microsoft’s compliance commitments. Enterprises already on Azure, or with strict networking and data residency requirements, often choose Azure OpenAI; teams wanting the newest features first sometimes prefer the OpenAI API.
Key Takeaways
- Azure OpenAI integrates with Azure security: Entra ID, private networking, Key Vault, monitoring.
- Regional deployment options help with data residency planning.
- New models and features may arrive on different timelines on each platform.
- Both platforms state that API data is not used to train models by default; review current terms.
- A landing zone for AI makes Azure OpenAI deployments secure and repeatable.
Comparison Table
| Factor | Azure OpenAI | OpenAI API |
|---|---|---|
| Provider | Microsoft (Azure) | OpenAI |
| Authentication | Entra ID, managed identities, keys | API keys, organization/project controls |
| Private networking | Private endpoints, VNet integration | Public endpoints |
| Regional deployment | Choose Azure regions and deployment types | Limited regional options |
| Governance | Azure Policy, RBAC, Defender for Cloud, Monitor | OpenAI platform controls |
| Billing | Azure subscription, commitments | OpenAI account |
| Feature timing | Can lag or differ by region | Often first access to new releases |
When to Choose Azure OpenAI
- You already run workloads on Azure and want one governance model.
- You need private network access with no public endpoint.
- Procurement prefers consolidated Microsoft billing and agreements.
- You need regional deployments for residency planning, such as in the US or close to the UAE.
- You want Azure-native monitoring and content safety integration.
When the OpenAI API May Fit
- Startups or product teams prioritizing the latest features.
- Workloads without strict private-network requirements.
- Teams not standardized on Azure.
Building a Secure Azure OpenAI Environment
- Deploy within an Azure landing zone with an AI-specific subscription.
- Disable public network access and use private endpoints.
- Use managed identities instead of keys.
- Route traffic through an API gateway for quotas, logging and chargeback.
- Enable content filtering and abuse monitoring settings appropriate to your use case.
- Log usage and integrate with Microsoft Sentinel.
Most enterprise use cases combine models with your data through RAG.

Frequently Asked Questions
Is Azure OpenAI the same as ChatGPT?
No. Azure OpenAI provides API access to OpenAI models within Azure for building applications. ChatGPT is OpenAI’s consumer and business chat product.
Does Azure OpenAI use our data to train models?
Microsoft states that prompts and completions in Azure OpenAI are not used to train OpenAI models. Review Microsoft’s current data privacy documentation.
Can Azure OpenAI be accessed privately?
Yes. Private endpoints let applications reach Azure OpenAI over your virtual network without public internet exposure.
Are the same models available on both platforms?
Many models are available on both, but availability, versions and regions can differ and change over time.
How is Azure OpenAI priced?
Typically by tokens processed, with options for provisioned throughput. Check the Azure pricing page for current rates.
Which is better for regulated industries?
Regulated organizations often prefer Azure OpenAI for private networking, Entra ID integration and alignment with existing Azure compliance controls.
