+**For the Azure samples (`azure_chat_multimodal.py` and `azure_responses_multimodal.py`, which use `FoundryChatClient`):**

+- `FOUNDRY_MODEL`: The name of your model deployment
 
-Optionally for Azure OpenAI:
-- `AZURE_OPENAI_API_VERSION`: The API version to use (default is `2024-10-21`)
-- `AZURE_OPENAI_API_KEY`: Your Azure OpenAI API key (if not using `AzureCliCredential`)
+These samples authenticate with `AzureCliCredential`, so run `az login` first.
 
 **Note:** You can also provide configuration directly in code instead of using environment variables:
