Clarify Azure AI Foundry format parameter documentation

[Copilot]

The format parameter documentation incorrectly stated users could find this value in the Azure AI Foundry portal. Users reported this information is not visible anywhere in the portal.

Changes

• Updated the note in the Azure AI Foundry integration docs to clarify that format specifies the model publisher/provider
• Added common examples: "OpenAI" for GPT models, "Microsoft" for Phi models
• Added link to AIFoundryModel API reference

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Op:
According to the docs (https://aspire.dev/integrations/cloud/azure/azure-ai-foundry/), the format parameter is supposed to be in the Foundry portal in the detail page of the model after the Quick facts section. Yet, I've checked every model page in the old and new foundry and there is no listed parameter named format available anywhere on any of these pages. Any docs on what this value should be set to for GPT-* models? Or where to find it?

Answer:

• https://learn.microsoft.com/dotnet/api/aspire.hosting.azure.aifoundrymodel
• https://learn.microsoft.com/dotnet/api/aspire.hosting.azure

Op: Ah, nice, ok. That helps a lot. Probably just need to make the docs a little clearer there.
