Azure OpenAI and Foundry

Use models you have deployed in Microsoft Foundry (Azure OpenAI).

Overview

On Azure you first deploy a model in your own resource and give the deployment a name. Loom needs that deployment name (not the model’s name), your resource name and a key.

Loom uses the current v1 route, which needs no API version.

Get a key

1
In the Azure portal, create (or open) a Microsoft Foundry or Azure OpenAI resource.
2
In Foundry, open Models, pick a model and Deploy it. Note the deployment name; you can choose it, and it defaults to the model’s name.
3
On the resource, open Keys and Endpoint (the menu wording varies slightly) and copy Key 1.
4
Your resource name is the part of the endpoint before .openai.azure.com, for example my-resource.

Cost. Billed through your Azure subscription. API keys give full access to the resource, so keep them private and rotate them.

Add it to Loom

1
Open Loom, then Providers in the menu, and choose Add provider.
2
Pick Azure OpenAI and Foundry (the search box finds it).
3
Fill in the fields in the table below.
4
Choose Connect. Loom checks the key and says how many models it found. If it cannot check, it says so, and you can Save anyway and try a message.
5
Open the model chip below the message box and pick a model.

Resource name: just the name, with no https:// and no dots.
Deployment names: one or more, separated by commas. The first one is the default. Azure cannot list models, so these are what the model picker shows.

If something goes wrong

What you see	What to do
401	Wrong key, or the key belongs to a different resource.
404, “DeploymentNotFound”	The deployment name does not match exactly. Copy it from the Deployments page.
403 from a network rule	The resource’s networking may only allow certain addresses. Allow your connection, or use a different network.
