How to use Claude 4.6 or any other model outside of chatGPT using startup credits?

Answer 1

Hello Gabriel Bourque,

Welcome to Microsoft Q&A and Thank you for reaching out.

I understand that you're interested in using Claude 4.6 (or another model) outside of the ChatGPT interface, for example:

• From your own application

Via API

Using your startup credits

Below is a steps,

Important Clarification About Startup Credits

Startup credits (for example, credits provided for ChatGPT Teams, Enterprise, or startup programs) are typically scoped to specific products and billing accounts.

In most cases:

Credits applied to ChatGPT do not automatically extend to external API usage.

API usage (OpenAI, Anthropic, or Azure AI Foundry) is billed separately.

Azure usage requires an Azure subscription with billing enabled.

So the key question is where your startup credits are allocated:

ChatGPT product billing

OpenAI API billing

Azure subscription credits

These are separate systems unless explicitly linked in your credit agreement.

How to Use Claude 4.6 Outside ChatGPT

There are two main supported approaches:

A. Use Claude via Direct API

If you have API access:

Obtain an API key

Call the Claude endpoint programmatically

Integrate it into your application

Example

API usage is billed against your API billing account, not your ChatGPT subscription, unless your startup credits specifically include API credits.

You would need to confirm that your credits apply to API usage.

B. Use Claude via Azure AI Foundry

If you want to use startup credits within Microsoft’s ecosystem:

1: Create or Use an Azure Subscription

You need a valid Azure subscription, A payment method on file, Startup credits applied to that Azure subscription.

2: Access Azure AI Foundry

Ensure you Have the required permissions.

Create a Foundry project in a supported region (for example, East US2 or Sweden Central, if Claude models are available there)

3: Deploy Claude 4.6

Deploy the Claude model within Azure AI Foundry

4: Call the Model via API

After deployment, you can Use REST APIs, Use SDKs, Authenticate via Microsoft Entra ID or API key

Billing is handled through your Azure subscription. If your startup credits are Azure credits, they will apply here.

Tracking Usage
