How to deploy a web application from chat playground using GPT-5-chat model?

Hi Cameron Stark

Welcome to Microsoft Q&A and Thanks for sharing the details.

“Deploy as a web app” option disappears when you switch from GPT‑4/4.1 to GPT‑5‑chat in the Azure AI Foundry (or Chat Playground). Here’s the current state based on Microsoft documentation and community updates:

1. GPT‑5‑chat is still in preview in Azure AI Foundry as of late 2025. It supports the Chat Completions API and Responses API, but web app deployment from the playground UI has not been enabled for GPT‑5 models yet. This is a platform limitation, not a permissions issue on your side.
2. The “Deploy as a web app” feature in the playground is tied to models that have full integration with Azure App Service publishing workflows. GPT‑4.x models currently support this, but GPT‑5‑chat does not.

Current capabilities for GPT‑5‑chat

• You can deploy GPT‑5‑chat as a model endpoint in Azure AI Foundry and call it from your own web app or containerized solution. This means:
  • Create a deployment in Azure AI Foundry.
  • Use the endpoint and API key in your custom app (e.g., via Azure Functions, Container Apps, or Static Web Apps).
• GPT‑5‑chat supports text and image input, text output, and advanced reasoning features, but no direct “one-click web app deployment” from the playground UI yet. [Foundry Mo...soft Learn | Learn.Microsoft.com], [ai.azure.com]
• Workarounds If you want a web app experience with GPT‑5‑chat now:
  1. Deploy the model in Azure AI Foundry (request access if gated).
  2. Use sample templates like Azure-Samples/sample-app-aoai-chatGPT or get-started-with-ai-chat to build your own web app.
  3. Host it on Azure App Service or Azure Container Apps, and configure environment variables with your GPT‑5‑chat endpoint and keys. [github.com], [github.com]

Currently, the ability to deploy web applications using the GPT-5-chat model is not mentioned in the provided context. It appears that the deployment option you are looking for may not be available for models beyond 4.1 at this time. If you are experiencing the disappearance of the 'Deploy as a web app' option when switching to GPT-5 or higher, it is likely due to the model's current limitations rather than an issue on your side or with permissions.

For the most accurate and up-to-date information, it would be advisable to check the official Azure documentation or announcements regarding the features and capabilities of the GPT-5-chat model in relation to web app deployment.
