This tutorial shows how to deploy and start using GPT-5 in Azure AI Foundry. You’ll learn how to access the Azure AI Foundry portal, select your project, explore the Model Catalog, and deploy the GPT-5 model to your own resource. Finally, it explains how to open the Chat Playground to interact with your deployed model and start testing prompts directly in the interface.

Make sure you create your own Azure AI Foundry resource, in case you dont know how to do it, follow this tutorial.

Lest go to https://ai.azure.com which is our Azure AI Foundry portal. When you login you will see the AI Foundry resource and the project. Select the project.

In there select the "Model catalog" option in the left menu.

In there you can see the list of models available you can search the one you want to use. In my case I will use, gpt-5.

In there click the "Use this model" option

Select "Create resource and deploy"

You have deployed your model!

To use it click the option "Playground" in the left menu.

In there select the option "Chat playground"

You can now chat with your deployment of gpt-5
