Claude usage in Azure foundry

Question

What will be the usage or the charge of the claude model in azure foundry? We have the azure credits in this subscription and we really want to try this model and spend the credits on our account. What will be the process for getting the charges directly from the azure credits rather than the credit card associated with it.

Answer 1

AFAIK, Claude models in Azure AI Foundry are billed as third-party Marketplace items, meaning their usage is typically not eligible for Azure sponsorship or startup credits. Because these models are provided by Anthropic rather than Microsoft directly, they are processed as external offerings that bypass your Azure credit balance. This often results in charges being applied directly to the credit card on file even if you have a significant remaining credit balance.

The billing process for these models follows a pay-as-you-go structure based on token consumption. In the Azure portal, these charges will appear under a different publisher type, such as Marketplace, rather than under native Azure services. Because they are not billed as first-party Azure resources, I'm not aware of any standard mechanism to redirect these specific third-party charges to draw from your internal Azure credits.

To ensure your Azure credits are used for AI workloads, you can focus on first-party models hosted and billed directly by Microsoft, such as those in the Azure OpenAI Service or Microsoft-published models like the Phi series. These native services are automatically covered by sponsorship credits. You can verify which models are eligible by checking the Publisher field in the AI Foundry model catalog; only models listed with Microsoft as the publisher will consume your subscription credits.

Hi Sabyasachi Sarkar,

Claude models are supported in Azure AI Foundry, but there are a few important things to check if you are trying to use them.

• Claude models in Foundry are provided by Anthropic as partner models. This means they are available through the Foundry model catalog and billed through Azure Marketplace, not as native Azure OpenAI models. You need a paid Azure subscription with a valid billing method to deploy and use them. Free or credit-only subscriptions are not supported for Claude usage.
• Claude models are only available in limited regions today. Currently, you need to create your Foundry project in a supported region like East US 2 or Sweden Central. If your Foundry project is created in any other region, Claude models will not appear in the model catalog. This is one of the most common reasons users think Claude is not available.
• Make sure you are deploying the model correctly from the Foundry portal. Go to the Model catalog inside your Foundry project, search for Claude, select the required model like Claude Sonnet, Haiku, or Opus, and deploy it using the Global Standard deployment option. After deployment, you must use the deployment name when calling the API.
• For calling Claude models, Azure AI Foundry provides Azure-native endpoints and supports authentication using Microsoft Entra ID or API keys. You can call Claude using REST, Python, JavaScript, or other supported SDKs, similar to how you call other Foundry models. [platform.claude.com]

If you are seeing access or usage issues, double-check these points:

Your subscription type supports Marketplace purchases

Your Foundry project is in a supported region

The Claude model deployment status shows as successful

You are using the correct deployment name and endpoint when calling the model

Microsoft has shared official guidance here that explains deployment, region support, authentication, and API usage in detail, which is very helpful to review: https://learn.microsoft.com/en-us/azure/foundry/foundry-models/how-to/use-foundry-models-claude [learn.microsoft.com]

Hope this helps clarify how Claude usage works in Azure AI Foundry and what to check if you are facing issues.

Thankyou!
