Developers can access AI models using two main platforms:

OpenAI
Azure OpenAI

Both provide access to similar AI models, but the way authentication and deployment work is different.

In this article, we will understand the difference between OpenAI API keys and Azure OpenAI API keys.

OpenAI API Key

OpenAI provides direct access to AI models through its own platform.

Developers can sign up on the OpenAI website and generate an API key.

Example platform:

https://platform.openai.com

Steps to Get OpenAI API Key

Login to OpenAI platform.
Go to API Keys.
Click Create New Secret Key.

Example:

sk-xxxxxxxxxxxxxxxxxxxxxxxx

This key can be used directly with OpenAI APIs.

Example endpoint:

https://api.openai.com/v1/chat/completions

Azure OpenAI API Key

Azure OpenAI provides OpenAI models through Microsoft Azure infrastructure.

Instead of using OpenAI servers directly, the requests go through Azure services.

Azure OpenAI requires:

Azure resource
Model deployment
Endpoint
API key

Example API Key:

xxxxxxxxxxxxxxxxxxxxxxxx

Example Endpoint:

https://openai-demo.openai.azure.com/

Key Differences

OpenAI API

Hosted by OpenAI
Direct API usage
Simple setup
Single endpoint

Azure OpenAI

Hosted on Microsoft Azure
Requires resource creation
Requires model deployment
Uses Azure endpoint

When to Use OpenAI

Use OpenAI when:

You want quick setup
You are building prototypes
You want direct API access

When to Use Azure OpenAI

Use Azure OpenAI when:

You need enterprise security
You want Azure integration
Your organization already uses Azure cloud
You need regional deployment

Conclusion

Both OpenAI and Azure OpenAI provide access to powerful AI models.

OpenAI is easier for quick development, while Azure OpenAI is better suited for enterprise applications that require scalability, security, and integration with other Azure services.
