Microsoft Foundry / Azure AI Foundry | Boundary Documentation

Microsoft Foundry is the new way to use AI models on Azure, which is a simplified version of Azure-on-openai provider.

To use the Microsoft Foundry (Azure AI) (https://ai.azure.com), you can leverage the openai-generic provider.

Use the Completions API setup to make it work with BAML.

Example:

BAML

1 client<llm> MyClient {
2   provider "openai-generic"
3   options {
4     // use the API key it indicates in the 'models' sidebar navigation menu, and clicking on the model you want to use
5     base_url "https://boundarydev-resource.openai.azure.com/openai/v1/"
6     api_key env.AZURE_AI_FOUNDRY_API_KEY
7     model "gpt-5-mini" // use the model you actually deployed
8   }
9 }

See here to see how to get your API key and base url:

1	client<llm> MyClient {
2	provider "openai-generic"
3	options {
4	// use the API key it indicates in the 'models' sidebar navigation menu, and clicking on the model you want to use
5	base_url "https://boundarydev-resource.openai.azure.com/openai/v1/"
6	api_key env.AZURE_AI_FOUNDRY_API_KEY
7	model "gpt-5-mini" // use the model you actually deployed
8	}
9	}
